Re: I'm an owner! 1975 Islander 22
Well folks, ya want the good news or the bad news first?
I'll give ya the bad first since it really ain't so bad.
The AmyAble is winterized. No more cruises till spring.
Now for the good news - and here's why I'm glad I got to run the boat some this year. I didn't really know if the outdrive had any problems, I knew the motor ran fine on land, but I didn't know how it would behave in real use, I didn't really know if either had any hidden problems that you don't see until you begin using it in the real world - things like a cracked engine block or leaking oil seals in the O/D. The scary stuff. Well I think I ran the boat enough this year, in real world usage, that the signs of these problems would have been obvious when winterizing today.
Well as I winterized the boat today, I changed the motor oil and the outdrive gear lube, this was the first time I'd changed the motor oil since I bought the motor. The oil on the dipstick looked new when I bought the motor (he told me he'd just changed it). The oil was black and looked used when it came out tonight, but
not one hint of water or milkiness/cloudiness or metal shavings in the motor oil or outdrive gear lube - and I looked. Hard. I also pulled out the expected amounts of both fluids, so nothing was leaking or burning up in use. That makes me feel a whole helluva lot more comfortable about the whole project. I think I can actually say I have a solid and well-running drivetrain (3rd propeller's a charm!).
Here's what I did today:
Added Stabil to fuel tank
Ran motor on muffs until warm
Changed motor oil
Ran motor until warm looking for oil leaks - found none ;-)
Pulled fuel tank connection
Squirted fogging oil into carb until motor died
Pulled spark plugs and squirted fogging oil into each cylinder
Pulled coil wire and turned motor over for a few seconds to get fogging oil coated and spread all over everything internally
Drained all water from engine cooling system, checking open drains with wire to make sure they weren't clogged and holding water (one was!)
Changed outdrive gear lube
Closed motor drains and filled with this stuff:
Question: looking into the thermostat housing and manifold passages where the cooling water goes, I saw what I can only describe as a brown fuzziness coating the side walls. Not clogging anything up, just a light layer of *muck* on the walls. Is there some "miracle" flushing additive I can run through there in the spring to really flush it out to get down to clean metal in there?
