496 with Whipple
 

I have a 2004 288 sunsation with a 496 and a Whipple it has a 120 thermostat in it and the water temp goes to 185 under full throttle at idle it is 130 do u think I should put in a transom water pick up?

that what we did,and our engines made 700hp and never over heated.had about 30lbs of water pressure.also make sure you can get rid off the water thru your exhaust,need alot of flow to keep her cool.

I am going to put a transom water pickup on it where should I install it at

away from the line of the prop
