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 |
huh? are saying to wrap the motor in tin foil in case aliens attack?

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?

Why? Because a $30.00 part and 1 hour of my time beats a overheated
motor and being stuck on the water. That is why. Paul Dougherty Sunny wrote in message m... Paul Dougherty wrote: I agree with everyone else. But I would replace the impeller. Why?
