Iím new to the website and new to the jet boat world. I bought a 1994 commander jet boat with a stock 454 and water cooled exhaust. I believe it has an American Hydro Pump. I just had the motor rebuilt and its ready to put back in the boat, "I bought the boat with the motor already removed". My main question is how do I properly run the cooling hoses to the motor and exhaust to prevent over pressurizing the motor cooling jackets and still provide enough volume to maintain the engine temperature within its nominal operating range? Does anyone have any diagrams with locations of pressure regulators, pressure relief valves etc....? I am installing the motor, rewiring everything and having the interior redone. I plan on doing all the work myself except the interior. I have restored several cars but not a boat. Any help, advice, smart ass comments, suggestions....will be greatly appreciated. Also need to know what should I set the timing at and do marine motors use vacuum timing advance? This is a stock motor with stock pump. Any other tips or problems to expect during this install please voice your experience. I am all ears!!
