I just dropped the boat off at a four winns dealership yesterday, so
we'll see what they can find. When I turned the outdrive all the way
to one side you can get a good look at the bellows. and there is two.
The one on top had a hole the diameter of a pencil in it. Plus there
is a hose that is for the bringing the coolant into the engine and
that looks pretty old, so they are gonna replace both. I wil give you
more updates as I get some news
Thanks

Again based on my merc experience the top bellows is the input shaft
connecting the engine to outdrive. *You really don't want water in
that as it will cause all sorts of damage. *But it should not ahve
anything to do with your overheating.

The lower bellows is probably the exhaust. *I'd make sure that the
dealer checks that out closely as well. *On the mercs if you do any of
it you usually do it all, both bellows, water hose, and shifter
bellows. *I think the volves shift at the top but I don't know if they
have a small bellows for a shift cable or not.

Your boat is not all that old for them to go bad (some mercs last 20
years easy) so again I'd try to make sure that the overheating is
resolved. *Hot exhaust will damage the various rubber parts pretty
quickly. *You should not use the boat until you can keep the water
temp well below 200. *160 is usually the higher thermostat on boats.
Not to mention there is the possibilty of other engine damage from
cooling problems.

Agreed.

One thing the dealership should do after replacing th bad parts, is to
muff it and let it run to see if the temp will be satisfactory.
Nothing like taking anything out after parts are changed to find that
it didn't cure the problem.


seen it before.
