Hi Jim:I think it's part 2. Though she is not very heavy. I'm about 170 and she's CONSIDERABLY lighter (never know who's reading...)...
I really think it is probably a marginal cooling situation.
She sits on the aft seat with me, so the engine is not being tilted such that the water intakes are riding in the air.
So what types of things cause the cooling system to be marginal?
I've been reading as much as I can on impellers and waterpumps. In addition to searching here, iBoats.com has some good articles on swapping out the impeller. It sounds like something I can do.
Is there any way to get at the water channels in the motor to see if they are blocked? Or do you need to tear the engine down to do that?
Maybe it's a stupid question, but if I drop the lower unit and swap out the impeller, and remove the thermostats, can I probe around with something to see? A coat hanger or ? Or do I risk making things even worse?
Could carbon buildup in the engine cause the cooling system to have problems?
I was reading with interest the articles about SeaFoam and wondering if that could be contributing.
Thanks,
Russ
