I'm new to the boat thing. But really what's the advantage to cooling your headers other then the engine bay stays cool ? My family has a few muscle cars. 500-750hp. And the header don't need to be cooled. So what's the catch ????

Your boat is constantly operating at higher RPMs, thus creating a lot more heat.
Sometimes with open engine compartments, often seen in jet boats, you can run headers that are not cooled.
No way you can do this with the traditional engine compartment and engine hatch.

Also without cooled / water cooled exhaust systems in boats that have enclosed engine compartments , if the engine hatch and interior do not catch on FIRE FIRST - then 4 sure your fuel will boil off from the extreme heat inside the engine compartment - your engine could stall while running or after shut down the engine will never restart because the fuel boiled away from that extreme exhaust heat / heat soak.. Also your engine wiring harnesses will not live very long either inside a enclosed engine compartment with NON COOLED exhaust system nor will your exhaust hoses and exhaust bellows

Listen, all cars guys that come over to boating get hung up on the exhaust thing 1st. Then the cam.
That includes most all of us.
The next new guy here is going to question the same things off the bat.
This same thread gets started many times a year.
