Re: Inboard exhaust manifold question
You will find there are 2 types of fresh water cooling. 1 is called a 1/2 system, that uses raw water to cool manifolds and rizers . 2nd type cools only the rizers with raw water. Find either a good photo of both plumbing systems ,or find a person who knows by looking which system you have. DO NOT CHEAP OUT ON MANIFOLDS OR RIZERS. George
