Not quite sure haha. As I am new in the performance boating scene. Have twin mercury racing 500 EFIs which ran amazing all summer long. Always fresh water before I got the boat (beginning of summer). Engines have 450 hours on them and wasn't sure if valves and whatnot needed to be checked and whatever else.
