Never considered it a marine engine? Here is a quote from my original posting, "This engine spent most, if not all, of its life in a fresh water jet boat." Also, here is another from the 3rd page, "I may have also been a marine engine from day one, but the stamp on the pad was NOT added." The "I" in that quote should have been It. I am very interested in learning the true history of this engine. I like to think of myself as an open minded person, maybe I have been fooling myself. Where ever this engine was originally installed I am fairly certain it left the plant with the heads that on with it now.
