More Power! Basically a racing cam. Is a source for real bad damage in a
boat, as the high overlap can cause negative pressure in the exhaust and
suck water into the cylinder. Most likely used on Dry Stacks, or stacks
where a little water is injected near the exit to meet the exhaust laws.
e.g. V drive ski boats (Mandella, etc.) Or jetdrive low profile ski boats
