I have a 1991 Comp that just blew out a head gasket, and the head is shot. The boat is otherwise in good shape and was running well until this happened. I have several questions for the group:

1- Is around $4000 a reasonable price for a replacement engine, including labor?
2- Should I take a chance and just replace one or both heads? My mechanic, who I think is excellent, thinks that for the price difference, I should just go ahead and replace the whole engine.

Any opinions would be welcome.
