I have just fitted a new motor to my jet boat. Its a 350 Chevy with a 671 Weiand blower running at a low 6-8 psi boost. Its not a race boat but I do like to put the pedal down now and then. What is the best method for me to cool my motor? Raw water? Water pump or no water pump? Thermostat or no thermostat? Any ides appreciated. P.S Its not really common practice to run blowers in family boats here in New Zealand so I am looking up to you Americans to steer me in the right direction!
