9.9hp outboard question ?
Hi, I have the 9.9 OMC use as trolling more than high speed, probably 99%
trolling 1% higher speed and it works fantastic for years and now this year it just isn't idling. It is starting with help of choke and runs at higher RPM then when try to idle or lower RPM it stalls out. If I hit the choke I can stop the stall but same situation happens. I changed the fuel, have new hose now, new plugs and engine is newer model with gear shift in the front, maybe about 12 years old. I may have ran a few tanks of high test with the ethenol or methonal or alcohol in it that the Sonoco sells. I put that high test in it last couple years. Northern Ontario and runs in fresh water only and seasonal. Funny thing is it worked fantastic last year and now this year just wont idle, our winter wasn't that bad, I storred it correctly. Any suggestions or recommendations to try? thnx |

Any suggestions or recommendations to try? thnx That's easy. The carburetor has gotten some water or shellac or other crud from old fuel sitting in the float bowl from the last time you used it. You must remove the carburetor and remove the float bowl. Then you need to clean any scum, water and other residue from the float bowl and from the jets (orifices) you can see and/or remove. A bristle pulled from a wire brush is often an efficient way to clean the crud out of the small orifices. You probably have a low-speed orifice clogged as it won't idle but chances are ALL the orifices have some degree of crud in them. Best to clean them all thoroughly while you have it apart.

Hi
Thank you for the reply. I see there was a bleeder screw at the bottom of the bowl of the carb, I opened that up and was able to push (via squeezing) the bulb so I see the fuel coming out. You still think it requires the carb to be removed and cleaned out? I did it to my rototiller and was successful, I can do it , but took a long time. Looks compacted in there. Do you think the fuel with today's alcohol caused anything? I found a station that sells zero alcohol in their fuel but that wasn't easy, it seems everyone today has the alcohol in their fuel. I was worried it was that causing some problem maybe a seal or neoprene seal was eaten. Thanks for the advice, looks like this weekend is booked cleaning the carb. Any more advice is appreciated.

It's not necessarily the alcohol that's the problem but rather the fuel seems to 'go stale' rather fast these days. It used to be gasoline would stay usable for years. But now, it goes bad - i.e. turns to a sludge like material that clogs small orifices. They make a product called Sta-bil (SP?) that you can add to fuel before storing a motor for months that keeps it viable. But raw fuel just seems to have a way too short shelf life anymore. I always run my motor until the float bowl is dry if I know I won't be using it for even a week or two. This means removing the fuel hose and running it while pressing the built in Shrader valve mechanism until the fuel pump pumps air and the float bowl is rendered empty by the venturi action of the carburetor. A dry float bowl will keep the jets clean. Wilbur Hubbard |

Ok,
Thanks Wilbur, your explaination is appreciated. I will pay closer attention to my fuels. Now I will focus on cleaning this carburater. It is a big difference in performacne in only a short storage season. While our winter wasn't that bad or long and I always use the high test I am shocked that the gas gummed up that quickly. I will begin tackling this carb and cleaning it. thanks again "Wilbur Hubbard" wrote in message anews.com... "Tom" wrote in message ... Hi Thank you for the reply.

Hi
When you say "Manual Clean" you obviously meant I had to take that carb off and clean it within. After seeing a bunch of utube cleanings I wonder if I could get away with a cleaning with carb cleaner. I can set up a small tank and run it with 50-1 and carb cleaner for about 10 minutes, and spray some carb cleaner into the carb. What you recommend is obviously the proper way but what do you say about a short cut or saving me all the time and removal of the carb. This engine might be newer than I suggested and it is pretty compacted and tight in there. I figure there are 5 things I must take out to get at the carb, not to mention all the mechinism. Are solvent cleaning or cleaners any good? Could you comment on that please? In Ontario I am not sure what cleaner is available but I can go to the store to get. Any suggestions or comments on this plan? Thanks much for your help. "Tom" wrote in message ... Ok, Thanks Wilbur, your explaination is appreciated. I will pay closer attention to my fuels.

Hi again
If you can comment on one more issue I forgot to mention. I am truly thankful. The OMC plastic gas tank (5gal) I have has a guage on it. Just plain guage E - 1/2- F style, not round, just glass face with four screws holding the guage onto the tank with a gasket. Now, this started leaking (at the gasket) about 2 years ago, now after I filled it up with fuel from Sonoco High Test with Alcohol (10%) I think and both that gasket kept leaking and the face glass holding the guage was leaking and the little piece of glass actually came out. So I am wondering about the alcohol in the fuel. Something caused it to leak and I think it is the alcohol, and I am thinking there may be damage in the fuel pump system or somewhere along the line there somewhere. Am I worrying for nothing? Is it coincidence? Is there any relation? Thanks for any tips. "Tom" wrote in message ... Hi When you say "Manual Clean" you obviously meant I had to take that carb off and clean it within.

Tom,
I think that Wilbur's advice to give the carb a good cleaning is good. From your description of tight space around the carb, I suspect that you'll need to dismount the carb to do this. You can spray carb cleaner around , maybe it will work. Many of the posters here live in the US and won't be able to advise you on the composition of gas in your province. Ask some locals. Dave M. |

Tried the Sea Foam for a couple days, really hard to keep that engine
running. Runs in high idle but get lower and wants to stall. Choke stops the stall but keeping it in High idle is worring me too much. And now looks like the impeller as I am watching the water outlet closely but tonight it wasn't working and then steam was venting out so I stopped. I am trying to run as much of that SeaFoam through as I can. I put about 20% of the can into a 2.5gal can mixed 50:1 with fresh high test with no alcohol. Looks like going to have to try taking off the carb and cleaning it out. Shouldn't be a problem, it has run nice for near 10 years as trolling motor and never missed a beat and just this season has failed. So must go to the west marine near by get the impeller kit . Is there a carb kit or anything else I would need to do a 10 year service? Thnx,, "WaIIy" wrote in message ...

No way, no mechanic. I am doing this myself.
First time for everything, besides, I just love the look on mechanic's faces when bringing a pile of something and asking them to help put it back together. But I bought the impeller kits today for both engines and will try that first. Then take the carb off and clean it and put it back together again. Any tips on those idle screws? What is the secret to not screwing them up? Iwas going to turn til tight and count the turns and mark where it is exactly now. thnx "Wayne.B" wrote in message ...

Are you aware of the price of a new carburetor for a small outboard these days? Probably two or three hundred bucks. They most certainly are NOT a throwaway item just because some mechanic is not skilled enough to know how to clean the offending parts. Any decent home mechanic will have no trouble cleaning the crud out of clogged jets. They are visible and accessible. No special tools required. In most carbs I've cleaned all it takes is a couple of screwdrivers and a bristle pulled from a wire brush. The clogged orifices will be easily accessible. Wilbur Hubbard |

WRONG! http://www.boats.net/parts/search/Me...9A)/parts.html Just like I said two or three hundred bucks for such a carburetor. Too expensive just to replace because a mechanic is either too stupid or lazy to clean the crud out of the orifices. It takes all of one half hour to clean the crud out.

Yes, I think I am going to tackle it. I can clean it. I have watched it on
utube dozen times now so as long as staying focused and putting everything back together properly. I also was concerned about the settings on the carb when putting them back. Those idle screws need to be thought out as well and other than that it looks pretty straight forward. I have gotten quotes from marina machanics who would love to do this and they are around the 250 mark plus taxes. So you are taking a risk with them sometimes so buying the new carb outright is about the same price so I would have to go that direction before having the marina do it. I will do it myself. After I do both impellers. I will let you know how I do, but some far less important things have come up and must get them done first. thnx "Wilbur Hubbard" wrote in message anews.com...

Thanks Bruce
I took the motor for a spin on the weekend, thought it would clear the clog and I ran some SeaFoam through it but it did nothing to improve the lower idle. Higher speed the motor didn't miss a beat, but slowing the throttle down it wanted to stall and pulling the choke was stopping the stall. But nothing corrected the issue. Looks like I will have to remove and clean the carb. Is there any procedure for setting those idle screws? Other than where they are now, I would hope they are in the right spot. Anyone have any ideas where those screws should be? I can do what you suggest Bruce and count the turns and put back in same spot, but what if that spot is wrong spot? Some utube videos say tighten the screw then come back 1.5 turns. Thanks for the ideas "Bruce" wrote in message ...

... Thanks Bruce Some utube videos say tighten the screw then come back 1.5 turns. That's the ticket. That's the starting point. That will get you up and running. Lightly bottom the screw then back it out one and a half turns. When the motor warms up you can fiddle with it while the engine is idling in gear to make it as smooth as possible. With what you just said it appears that only the low speed jet is clogged. That's the one where a bristle pulled from a wire brush and used to clear the orifice will do the job nicely. No need to do much more than remove the float bowl and locate the low speed orifice and use the bristle to unclog it. Wilbur Hubbard |

Some utube videos say tighten the screw then come back 1.5 turns. Thanks for the ideas Idle speed or mixture is not really that important an adjustment as it is effective only in the idle range. If you had no idea at all you could just get the engine running and holding the RPM above the idle range make an adjustment. Retard the throttle until the RPM falls into the idle range and see whether the engine runs smoothly. If it doesn't try a different adjustment, either open a bit or closed a bit. The Idle Speed do the same. Get it to run. Make a preliminary adjustment and see how it goes, adjust to taste :-) If you have some doubt about the present adjustment why not change it? A quarter - half a turn in either direction. See how it goes. You can always return to the original setting. It is not like the adjustment is some secret setting. Either the engine will run smoother, or not as smooth (smooth is good) and almost anyone should be able to figure out is it better or worse. |

Hi
Thanks gentlemen for your advice. I am waiting now for the carb repair kit to come in. It costs about 24 dollars for complete kit containing float. Watching a few u-tubes on mechanics doing carb cleaning they all talk about the damage today's alcohol additives does to these components. I will certainly be paying much closer attention to the fuels I use in these engines. I have found some gas stations that have no alcohol in their fuel and will start adding stableizer to the fuel from now on to prevent gumming and these issues. Should these outboards be runned dry after using? Is leaving fuel in the carbs good idea (stablized) or should run dry then that leaves air in there, is that worse? Thanks again gentlemen for the tips, I will let you know how I managed to do my second carb servicing (first one was my 70 old rotto tiller) and that was just a take it off, clean it, flush it, rinse it, soak it, clean that tank and it started first pull and ran like a dream (until it started stalling again but now I leave the tank full and runs good). If it aint one thing it is always another, thanks again 73s "Bruce" wrote in message ...

9.9hp outboard question ?
Thanks boys for all the advice, I took the carb off, replaced the parts that
came with the kit and the float and you were absolutely right. There was so much varnish in those jets, I just used a whole can of carb cleaner and a compressed air thing and kept cleaning and it all came out and while I haven't started it yet, I know that those holes were clogged, there was corrosion and water and other stuff. I am going to pay more closer attention to the fuel. The blue sta-bil is not a must. One question, many were talking about that idle screw on the carb. I think it is the needle valve for slow speed. On the side of the starboard side of the carb. Some said work it in to the end then back it out 1.5 turns. Mine was worked into the end then backed out 4.25 turns. I haven't started it yet because replacing fuel lines with the newer ones so will soon but where should that idle screw be? 1.5 or 4.25 ? I have it at 4.25 now but wondering if that is a problem or how to set that. Thanks "Wayne B" wrote in message ...

Yes thanks, I just mixed in some marine Sta-Bil to the fresh tank of none

Interesting update.
Got the 9.9 running Ok, I put the idle screw to 1.75 and started and it ran high so backed it out to where it was about at 4.25 it seemed to run ok in the driveway with earmuffs, idled very nice. Thanks so much for the advice on that 9.9, so now that I cleaned the carb and impeller I think the thermostat may be failing. It isn't a sal****er unit but its been in salt water many times. About 15 years old. Either the muffs werent tight or the thermostat because I took the thermostate apart and soaked that brass part in some CLR and cleaned the gunk out of there and put it back and really started peeing out that pee hole thing and idled nice. Feel happy and proud I learned a lot on that 9.9. So started the main engine the 225hp. Remember few days ago I changed the impeller in that and thought all went well there. Now here is my situation , I never started the engine in the driveway before with earmuffs, only with that thread in female part at the back where the pee hole view thing pulls out with sparkplug socket size wrench. So, for first time using the earmuffs I notice the pee hole squirter isn't as powerful as it was in the water. Maybe half, And notice water gushing out between that space between lower unit and shaft housing, not sure if that is supposed to gush out from there, I can only use the earmuffs in the driveway. I think maybe I might have to pull that lower part off again to see if I missed something when putting it back together. It was tricky as had to take the side cowl off to disingage that shifter rod. So thats my plan in the morning. Unless one of you guys thinks that is normal for a 225hp 1999 to run its water cooling system like that with earmuffs. I should have paid closer attention to it before in the driveway, I only used that back feeder part. But in the river it ****es out much more powerful, Any ideas? thanks "WaIIy" wrote in message ...

9.9hp outboard question ?
Thanks for the words of encouragement,, fact is there is no day job as of
lately so I am happy to do this on my own. So looks like this morning's job is dropping that lower end again and seeing if there is something missing. There were a few extra parts in the kit that i have for the impeller change , i thought I put every part back on that I took off that was available to switch. I think when putting it back together the tube that goes into the rubber grommet thing there that is on the top of impeller housing might not have completely went into that tube thing. I can only think that is the issue. Or, I can go drop the boat in the river and see if it pees out much more powerful,,, then everything is correct. This is my prediciment. I think everything went back together properly, yet never noticed water coming out from that space before, and never ran the engine on muffs in the driveway. Would running the engine on muffs make the pee hole water tube outlet less powerful? Or should it be exactly the same on water on muffs on that back connection ??

9.9hp outboard question ?
Little update,,
Had to take a break because it started pouring rain so covered up the engine and waiting for a about an hour (2 sandwiches, cold pops and some snacks). Anyway I lowered that lower unit again on the 225hp and found that the rubber sleeve, or rubber tube grommet that fits inside the impeller housing cover got caught on the end of that copper pipe coming down from above. Where the copper pipe has to fit into the impeller housing tubes there was spun and partially was blocking the tube and flow. Now this would explain both the gushing out the bottom and reduced pressure coming from that pee hole. I hope. Havent started yet. But that copper pipe wasn't perfectly round it had some kind of a dent looking at it, it wasn't perfectly cemetrical so I sanded it a bit, took off the sharp edges, rounded it, cleaned it then lubed it and lubed the female rubber pieces it is supposed to mate into right down to that rubber grommet sleeve at the bottom which was spun because of that oblonged shape copper.

So looks like this morning's job is dropping that lower end again and seeing if there is something missing. There were a few extra parts in the kit that i have for the impeller change , i thought I put every part back on that I took off that was available to switch. I think when putting it back together the tube that goes into the rubber grommet thing there that is on the top of impeller housing might not have completely went into that tube thing. I can only think that is the issue. Or, I can go drop the boat in the river and see if it pees out much more powerful,,, then everything is correct. This is my prediciment. I think everything went back together properly, yet never noticed water coming out from that space before, and never ran the engine on muffs in the driveway. Would running the engine on muffs make the pee hole water tube outlet less powerful? Or should it be exactly the same on water on muffs on that back connection ??

Thanks so much for the advice on that 9.9, so now that I cleaned the carb and impeller I think the thermostat may be failing. It isn't a sal****er unit but its been in salt water many times. About 15 years old. Either the muffs werent tight or the thermostat because I took the thermostate apart and soaked that brass part in some CLR and cleaned the gunk out of there and put it back and really started peeing out that pee hole thing and idled nice. Feel happy and proud I learned a lot on that 9.9. So started the main engine the 225hp. Remember few days ago I changed the impeller in that and thought all went well there. Now here is my situation , I never started the engine in the driveway before with earmuffs, only with that thread in female part at the back where the pee hole view thing pulls out with sparkplug socket size wrench. So, for first time using the earmuffs I notice the pee hole squirter isn't as powerful as it was in the water. Maybe half, And notice water gushing out between that space between lower unit and shaft housing, not sure if that is supposed to gush out from there, I can only use the earmuffs in the driveway. I think maybe I might have to pull that lower part off again to see if I missed something when putting it back together. It was tricky as had to take the side cowl off to disingage that shifter rod. So thats my plan in the morning. Unless one of you guys thinks that is normal for a 225hp 1999 to run its water cooling system like that with earmuffs. I should have paid closer attention to it before in the driveway, I only used that back feeder part. But in the river it ****es out much more powerful, Any ideas? thanks Good on yer. Don't give up the day job yet but you are certainly getting there. Cheers, Bruce |
9.9hp outboard question ?
New update
All went together like it was ok, and started and now I have that pressure i knew was at that pee hole so much more pressure at that peehole. That rubber sleeve that was turned sideways that was blocking the tube must have been my troubles. Still one question. I still see water, though much much less than before is coming out of those intentional spaces there between the lower unit and shaft. Is that normal? There were no gaskets there, doesn't look like any should go there. So when it is running in the driveway with the muffs should there be water coming out of that space? I am talking about that space on the moter shaft housing where those four bolts held the lower unit on. That space is actually 4 spaces about 1 millimeter and is on both sides. Is there supposed to be a small amount of water running out of there while the engine is running? Actually was also coming out as soon as I turned the hose pressure on before I started the motor. Not much water, about a liter every few minutes maybe. It was gushing out before but now down to a trickle. Please let me know if that is normal or not as I will dive down there again to make sure it is all right again. The replacement kit wasn't as nice as the original parts so that might have had something to do with it as I want to re-use some of those originals in good shape. Thanks for the advice anyone who can add. "Tom" wrote in message ... Little update,, Had to take a break because it started pouring rain so covered up the engine and waiting for a about an hour (2 sandwiches, cold pops and some snacks). Anyway I lowered that lower unit again on the 225hp and found that the rubber sleeve, or rubber tube grommet that fits inside the impeller housing cover got caught on the end of that copper pipe coming down from above. Where the copper pipe has to fit into the impeller housing tubes there was spun and partially was blocking the tube and flow.
