And what that does, is gives 40 more hp than stock. It's a 4wd not a race car so not over the top, but sounds like the marine industry has placed it's own take on HO.
Really need to see full specs for both marine engines, the stock and HO, and should be able to tell if it is putting out more ponies or not or just delivering the same hp in different manners /revs. If I missed the specs somewhere I apologise
Interesting topic
