Advice on Dormant Outboard Motor
Appreciate some thoughts on putting my outboard motor (30 hp
Mariner)back into service. I knew it would be out of operation for awhile so I flushed it out good, ran the carb dry, changed the lower unit oil, squirted some two stroke oil into the cylinders via the spark plug holes and pulled the starter cord a couple of times. Time slipped on by and the press of other things kept me away from my boat. Now, when I'm ready to start using it again, I realize that 10 years have passed since I "serviced" it. I'm not sure how to proceed. Do I have a piece of junk, suitable only as an anchor or scrap aluminum? Should I simply get some fresh gas, hook up the battery and try to fire it up? Should I tear it down and replace gaskets, pump impeller, etc. before trying to fire it up? Any advice appreciated. |

I second that motion, I tear NOTHING down unless I know it's broke or HAS a
problem. Only thing I'll add is that I prolly change the oil in the lower....and make sure I have my cell phone with me on the first couple of uses:-) Don I pulled the plugs, shot some WD-40 (CRC will also work) into the cylinders, pulled it through a couple of times, some more WD, pulled it through a few times, then more WD and gave it a good eight/ten pulls, checked the spark the old fashioned way, put it in gear and pulled it through a time or two, put the plugs back in and got ready I didn't quite double the recommended mixture (I can't remember if it was 100 or 50:1), but maybe about a 1/4 or so over so it would get a little more oil than necessary. Put a little of the mixture into a spray bottle and shot some into the carbs, then started her up. Nice thing, a grunt or two and wham - started, roughed it'self out a little bit, settled down and purred right along. I didn't push it out of idle for about five minutes, then put a little load on it, let it idle, then shut it off, took it to the lake and ran a tank full through it. Worked like a charm.

Couple of years ago a neighbour gave my son a '64 Evinrude 18hp which had been "stored" (lying in the dirt) under his cottage for at least 15 years of Canadian winters. I took the lid off and gave it a visual inspection. One of the fuel lines was obviously unfit for service (rotted) and was replaced. Pulled the spark plugs, they looked good and were gapped right, so back they went. Changed the gear oil, then installed it on a 12' aluminium cartopper. The motor started third pull and ran very nicely. My son has been running it almost daily for the past two seasons. It broke a reed last spring, but apart from that has been absolutely reliable. IMHO, don't mess with it unless you know it's broken :-) Sunny |

Why?
Because IF the impeller is dryrotted and breaks up, the shrapnel may well wind up going up the pipe and into the cooling system - where is is bound (by Murpheys Law) to find the most critical water passage and block it. Changing the impeller is VERY trivial compared to all the alternatives. Your sons motor is lucky is all. -W "Sunny" wrote in message news:kz%dd.31253 Why? It's not a trivial job, and IME there's no evidence impellers are harmed by dry storage. My son's motor is 40 years old, and still has the original impeller - despite sitting idle for 15+ years before being returned to service three years ago. Paul |

clems? have you ever taken apart the water pump on an outboard? If so, why is
it you can't remember just how small the outlet is? From: "Clams Canino" Date: 10/22/2004 12:52 AM Eastern Daylight Time Message-id: . net Why?

save yourself the hour's labor and send me the 30 bucks. just as effective,
and less effort. |

No, no, no.....you wrap the ALUMINUM foil around the outboard in case aliens attack. You use tin foil to make a hat so that the satellites can't spy on your brain waves.

i would also remove the carb and replace the gaskets.
sure, and renew your library card, which is a lot more useful replacing the replacing the gaskets. dood, have you ANY idea what gaskets look like, let alone what causes them to fail? If so, just why in hell did you post the following? From: (BenC) Date: 10/22/2004 9:08 PM Eastern Daylight Time Message-id: (Art Coe) wrote in message .com...

well that didnt take long did it jerx? having done this for as long as
i have i know exactly what the gaskets in a mariner of that vintage are made of. i dont think you do or have even a clue what fuel, heat time and corrosion do to them. maybe you need to run along and read a little to get up to speed. i have a better suggestion, post your vitriolic suggestions in the myriad of OT threads. i dont read them. ultimately art mine are just suggestions. i would suggest a visit to your local dealer for your own peace of mind and to prevent rowing home.

If the options were that cut'n'dried, I'd replace the impeller too... but why stop there? Ignition failure due to rotted insulation is at least as likely to leave one stranded. Last time I replaced an impeller ('72 Johnson 85hp), it took most of a day - driveshaft spline was frozen in the crank, and I had to make a wooden jig to push the lower unit off with hydraulic jacks. I don't take old machinery apart unless it needs taken apart - OTOH I don't trust it until it's earned my trust. Sunny Paul Dougherty Sunny wrote in message m...

Changing the impeller is VERY trivial compared to all the alternatives. Your sons motor is lucky is all. Luck, or fresh water? I've been running ancient outboards for 20 years in fresh water, and storing them outside in Canadian winters, and only ever replaced one impeller. I'm not sure what caused it to fail, because it looked great except for one vane broken off clean near the hub - and still intact inside the housing.

An ignition stranding can be easily fixed, a powerhead failure is a "catastrophic failure" type stranding.

Both. I could show you a dozen fresh water impellers that are cracked and
beaten. -W "Sunny" wrote in message news:1wjfd.8916 Luck, or fresh water? |
Sorry for starting a mini flame war, but I do appreciate all the
advice. Based on all the input I believe I will proceed as follows: 1. Visual inspection of hoses, wires, etc., make any repairs necessary and replace the lower unit lube. 2. Squirt some 2-stroke oil in the cylinders and pull the starter cord a few times (hopefully it will pull - if not I'll have a pretty good idea of what I've got on my hands). 3. Mix a small quantity of fuel/oil with a slightly richer portion of oil than usual (spec. is 50:1, maybe go 30 or 40:1). 4. Try and fire it up and run it for awhile in a barrel of water and see how it goes. 5. If it seems OK, probably take it to a shop for a check/tune up. 6. When I begin using it on the water again, bring along a kicker just in case. Again, thanks for the input. |

When you are running the motor in a barrel or just are
using muffs, make sure that water IS flowing out of the pee hole. This will show that water is circulating inside the motor itself and cooling it. As for bringing it down to a place to have it checked? Not a bad idea, but if your handy you can do it yourself. Changing the water pump impeller is generally a good thing to do. Whether you are in fresh water or salt water, a rubber impeller dry rots and then falls apart. Normally this happens when you are full throttle and the old motor doesnt have an over heat sensor (or its not tested and working) Nothing ruins a day on the water than a seized motor!
