os .90 marine engine cooling questions
So i picked up a pristine prather piranha with an os .90 marine engine. I saw this as a huge score , and am readying it for the lake house this weekend. My question about the motor is, the 90 has a double cooling jacket. I dont feel the flow from the rudder pick up is enough water volume for this engine. I am adding a second water pick up and this one is a larger diameter. Should i feed the head or the sleeve/casing jacket the higher volume water line?
