Mercruiser A-1 gear lube consumption
"jamesgangnc" wrote in message oups.com... It's just a little plastic plunger pump that fits in the top of quart gear lube bottles. The gear lube does not circulate but it is connected between the top and bottom halfs of the outdrive via small passage. This is so the gear lube can expand when hot. Because the passage is just a small hole the only way to get the drive properly filled is to pump the lube up from the bottom drain. If you pour it in the top it just traps the bottom full of air. Drive should be the down position when adding lube. I always said alphas were a bit of rube goldburg. They have not fundamentally changed since the whole idea of bolting the bottom of an outboard onto a auto engine started. The newer merc bravoes and volvoes are better designed from an engineering standpoint. But the alpha is not delicate and there are millions of them running around so the parts are cheap. If you are a diy're you will not have any trouble removing the outdrive or splitting the lower and upper halfs. The alignment tool is about $70 and is not very hard to do. A service manual is a must as there are tricks you need to know like it must be in forward gear to remove the outdrive. How heavy is the outdrive? And what has to be disconnected ? Very capable DIY-er, yeah, but I guess I didn't realize that I was buying into a high-maintenance endeavor like this, thats all. I mean, I'm not having to drop the transmission in my car every year to check input shaft/throwout bearing alignment, and change gear lube. I think my next boat will be an outboard so that I don't have to worry about as much stuff. Thanks for the additional information! Mr Wizzard wrote: "JohnH" wrote in message ...

The lube is heavier than air, and is viscious, so I don't see how you would get trapped air in the unit, and the filler hose (from the lube monitor) is about 3/8-1/2 inch. Rob |

Mercruiser A-1 gear lube consumption
The outdrive is a bit heavy. If you get everything just right you can
have the fin resting on a block of wood and sort of slide it out. I can remove and reinstall mine myself. Most service manuals do recomend you have a helper. It is simple to remove. Your really should get a service manual. Many people do not remove their outdrive every year. I take mine out every 2-3 years so I can lube the u-joints and generally check it out. I also split it to check the water pump. I change the lube on about that same schedule. I put around 100 hours on my boat in a summer. I do let a few drops of lube out the bottom periodically to check for water and the general condition of the lube. The lube actually looks good even when I change it but it only takes a couple bottles of lube so why not. I'm sure there are 20 year old alphas that have never been removed running around out there. Sort of depends on how much you care about stuff. Of course a few of those the owner misses what would be signs of an approaching problem and ends up replacing or rebuilding the entire unit. I think most of the outboards recomend that you split them to check the water pump every year. I would not argue that outboards have advantages over i/os. But it is no free ride and a comparible hp outboard will probably cost you $10k or more. And the parts for them are extremely expensive when they break. This is because they are low volume items. For any serious work they have to be removed from the transom and that takes a lift because big outboards are heavy. I like outboards for specific boating needs. We are into the ski/wakeboard/kneeboard/tube stuff and an outboard is just in the way when you are messing with ropes and getting people in and out of the rear of the boat. With an i/o I have a nice clear sundeck and built in full width swim platform. The i/o is well under the swim deck and out of the way. I might consider a full inboard but would never want an outboard for the way I use a boat. But to each his own and maybe an outboard would suit you. Boats are a high maintenance item. They are nothing like a car. They are in the water which creates problems and their mechanical parts are run a lot closer to the limits than a car. Drive your car around at 100 mph all the time and see how much maintenance you have to do to it. Car engines are loafing most of the time. It's the reverse in a boat, boat engines are almost always working pretty hard. Mr Wizzard wrote: "jamesgangnc" wrote in message oups.com...

Mercruiser A-1 gear lube consumption
The hole between the upper and lower unit is about 1/8 of an inch.
Getting air one way and lube the other way is just not going to work very well. When you fill the unit you need to get nearly a quart of lube in the lower unit. You need it filled before you use the thing. I can't argue that filling the top and waiting may eventually get the air out of the bottom might work. But I think it would take days. Filling form the bottom works fine and when you're done, your done. Just get the little plastic pump that goes on the top of a lube bottle. It works fine and a gazzilion people have been doing it this way forever. In the case of the overflow normally you have very little fluid changing places with air.

They will "purge" themselves during the first three to five trips, and consequently the oil level will drop. If the oil level continues dropping after the first 5 trips after an oil change, then you have a leak that needs to be fixed Mr Wizzard wrote: What's normal for gear lube consumption for the newer Alpha 1? I have a 2005 Bayliner 175 w/ Mercruiser 3.0L A-1 which has little plastuc gear lube monitor. Only had it out 2-3 times this year since winter, and I noticed that the fluid level is down about 1/2 inch below the "Add" line, and I'm concerned. Its *never* gotten that low before! Today we stoped in the middle of the lake and went swimming, wading, and what not, and I looked very hard for the "rainbow", and found nothing. No signs of a leak anywhere. No smell, no film, all dry, no rainbow on water. So if the Alpha-1 was leaking/seeping gear lube, where would it be going? prop shaft seal, shift lever? I wonder if its leaking inside the bellows for the drive shaft ? is there a way to see down in the bellows from the inside? I know everyone says that it should use NO gear lube, I'm just wondering if there is any acceptable amount of gear lube that a newer Alpha-1 can consume before being concerned? I have been running it pretty hard, and longer periods of WOT, could that make a difference ? Thanks! If you look here http://tinyurl.com/ryp3d you'll see an o-ring as part #4. My outdrive began leaking one year, and I didn't realize it until I noticed some discoloration in the water as I was sitting at the dock. I believe it was this o-ring that was replaced by the shop, but I'm not 100% sure. It was either an o-ring or seal in the outdrive. Once replaced the leak stopped. Interesting web page, thanks! However, like I said in an earlier post, there is absolutly no rainbow on the water anywhere (looked long and hard). Also, ans while we're on the subject, where does one get a "pump" to change the gear lube? - I read that you have to pump the lube "up" the drive from the bottom drain plug. WalMart. But I use a presurized 2 gallon (former) pesticide spray can with a homemade spigot. Homemade spigot ? is the drain plug a regular NPT thread ? And you can get enough pressure with a pump-up sprayer? (another stupid-ass maintenance/design deal). More physics than design. Filling from the bottom reduces/eliminates bubbles & trapped air resulting in a more complete fill. The lube is heavier than air, and is viscious, so I don't see how you would get trapped air in the unit, and the filler hose (from the lube monitor) is about 3/8-1/2 inch. Rob |

Mercruiser A-1 gear lube consumption
Pressure, and vacuum ? I sure hope not ! The gear lube
monitor bottle has a vented cap... so if you don't vent the unit with the upper vent plug and fill from the lower fill plug, you may have some better new method to recommend to the MerCruiser people... where are you putting your displaced air as you fill the gearcase? Heavier gear lube runs down the hose from the gear lube monitor container, and the lighter air travels up the hose, into the lube monitor and out the vented cap. But hell, I dunno - maybe there is some sort of check-valve on the hose between the gear lube monitor tank and the drive? Rob There is no check valve. I'm pretty sure filling the gearcase from the top would work. Could you give me a rough estimate as to how long it would take to fill an Alpha gearcase from the top. Seems to me that it would take a long...long...long...long...long time. Jim |

Mercruiser A-1 gear lube consumption
Thanks for all of the great info. I'm still greatly dissapointed.
As many of you recall, this 2005 Bayliner 175 is my first real boat (that I bought brand new jast June), and now I got this gear oil consumption problem. I've recently called the dealer about it too. Did some more tests, and find that it uses about 2 Oz of oil for every 1-hour of running. So, the question is, where is the most probable place for the leak? Prop seal, driveshaft seal, or water pump? And what could of done this? dealer dude (on phone) doesn't seem to think that engine alignment would do it. Would running it at excessive speed do it? Not too long ago, I was running it at WOT for really long periods of time - could that have done it? I've only had the thing out 4 times this year since winter - could something have happened over winter? (Seattle area). I did scrape the fin on drive way, but I consider that pretty minor. I did also take the prop off recently to do what the book said as "prop maintenance". Basically clean and lube the shaft, anf reassemble - any thing there I could have messed up? How rare is it to develop gear lube consumption problems on a 1-year old Alpha-1 I wonder? And are replacing seals somehting that I can do? (very mechaincally inclined). Issue is that dealer says they won't be able to get me in till late Aug. I was thinking that if its a prop seal, that maybe I can just replace it. Also, whats involved with changing the oil seal on the upper half? and the shift lever? So what, 4 places the lube can leak from, right? prop deal, upper drive shaft seal, shift lever, and water pump area? Thanks! "jamesgangnc" wrote in message oups.com... The outdrive is a bit heavy. If you get everything just right you can have the fin resting on a block of wood and sort of slide it out. I can remove and reinstall mine myself. Most service manuals do recomend you have a helper. It is simple to remove. Your really should get a service manual. Many people do not remove their outdrive every year. I take mine out every 2-3 years so I can lube the u-joints and generally check it out. I also split it to check the water pump. I change the lube on about that same schedule. I put around 100 hours on my boat in a summer. I do let a few drops of lube out the bottom periodically to check for water and the general condition of the lube. The lube actually looks good even when I change it but it only takes a couple bottles of lube so why not. I'm sure there are 20 year old alphas that have never been removed running around out there. Sort of depends on how much you care about stuff. Of course a few of those the owner misses what would be signs of an approaching problem and ends up replacing or rebuilding the entire unit. I think most of the outboards recomend that you split them to check the water pump every year. I would not argue that outboards have advantages over i/os. But it is no free ride and a comparible hp outboard will probably cost you $10k or more. And the parts for them are extremely expensive when they break. This is because they are low volume items. For any serious work they have to be removed from the transom and that takes a lift because big outboards are heavy. I like outboards for specific boating needs. We are into the ski/wakeboard/kneeboard/tube stuff and an outboard is just in the way when you are messing with ropes and getting people in and out of the rear of the boat. With an i/o I have a nice clear sundeck and built in full width swim platform. The i/o is well under the swim deck and out of the way. I might consider a full inboard but would never want an outboard for the way I use a boat. But to each his own and maybe an outboard would suit you. Boats are a high maintenance item. They are nothing like a car. They are in the water which creates problems and their mechanical parts are run a lot closer to the limits than a car. Drive your car around at 100 mph all the time and see how much maintenance you have to do to it. Car engines are loafing most of the time. It's the reverse in a boat, boat engines are almost always working pretty hard. Mr Wizzard wrote: "jamesgangnc" wrote in message oups.com... It's just a little plastic plunger pump that fits in the top of quart gear lube bottles. The gear lube does not circulate but it is connected between the top and bottom halfs of the outdrive via small passage. This is so the gear lube can expand when hot. Because the passage is just a small hole the only way to get the drive properly filled is to pump the lube up from the bottom drain. If you pour it in the top it just traps the bottom full of air. Drive should be the down position when adding lube. I always said alphas were a bit of rube goldburg. They have not fundamentally changed since the whole idea of bolting the bottom of an outboard onto a auto engine started. The newer merc bravoes and volvoes are better designed from an engineering standpoint. But the alpha is not delicate and there are millions of them running around so the parts are cheap. If you are a diy're you will not have any trouble removing the outdrive or splitting the lower and upper halfs. The alignment tool is about $70 and is not very hard to do. A service manual is a must as there are tricks you need to know like it must be in forward gear to remove the outdrive. How heavy is the outdrive? And what has to be disconnected ? Very capable DIY-er, yeah, but I guess I didn't realize that I was buying into a high-maintenance endeavor like this, thats all. I mean, I'm not having to drop the transmission in my car every year to check input shaft/throwout bearing alignment, and change gear lube. I think my next boat will be an outboard so that I don't have to worry about as much stuff. Thanks for the additional information! Mr Wizzard wrote: "JohnH" wrote in message ...

There is really no way to get much of a view into the bellows area. You have to pull the outdrive and check inside the belows for fluid. And then it's still hard to tell as the grease from the ujoints and coupler sometimes creates some oily fluid if it has been heavily lubed. Did you ever have the pump impeller replaced? Someone may have not used a new o-ring between the upper and lower unit when they were split. Have you checked the lower unit for water in the lube? To do this you carefully remove the lower plug just enough to get a few drops out to see that they are not milky or contain water. If it is still covered by a warrenty you can try to get it fixed. If not then as long as there was not any water getting in the outdrive I'd be inclined to just check for water a few times a year and live with it until the end of the season. The pull the outdrive and have it pressure tested. At our house this is not the time for the boat to be out of commission :-) Mr Wizzard wrote: "katekebo" wrote in message ups.com...

And if there is a "leak", out of curosity, why doesn't it leak in the driveway? (gravel pad). As I said, I see no signs anywhere. Is there a remote chance that there was an air bubble in the line somewhere from the factory from last June when I bought it, and it just boke loose somehow?
