Were not losing antifreeze...its almost like its just building pressure with no where to go.

The engine is getting very hott. It started smoking while we were docking. We ended up turning off the engine and walking the boat into the slip.

Any ideas how to find where that wire goes?? We cant see that half of the engine, we've tried feeling around, and using a small mirror, but we cannot figure out where this wire goes.

It seems you may have more than one problem. The pressure cap is supposed to release excess pressure. You should probably replace yours.

As far as the wire goes - is the oil pressure gauge working? How about the temp. gauge and temp alarm? How about the tach?

I would recommend buying the parts and service manual and using the diagrams to see where the wire should go.

The most likely cause of the problems you are having is an air lock in the cooling system, or perhaps a mistake when reconnecting everything after re-installing the heat exchanger. The manual would help sort this out as well.
