I greatly appreciate everyones advice on removing the water jackets and cleaning them out to resolve an overheating problem on my '97 Yamaha 115. Well, I just pulled the jackets off and pealed the gaskets off. It appears to me that they are not coroded at all. There are a few small rust spots but certainly not enough to restrict water flow.
The thermosats (I'm assuming they are thermostasts) up near the top of the jacket look a bit worse for wear. There looks like there's some crud built up in the springs of one of the thermostats. Could this be the overheating issue?
I'm not sure where to look next and would greatly appreciate any advice. I suppose that I could hook up a hose to see if water is even getting to the water jackets.
I sure hate taking her to the local boat repair pirates, just to drop $1000.00 and not get any results.
Thanks, Jfro Haleyhead
