Answeris it spiking right into the overheat zone or is it just running hotter? you can usually run an engine at 75% up on the gage with no harm to the engine. modern coolant systems keep typical operating temps way lower than older vehicles, but when you work them they will heat up. also, how big a boat? if you are trying to pull the RMS Titanic with a V6 4x2 you are not going to have a cool running engine.
