Sorry if I should have posted this in of topic but im looking at making a 10-12ft v hull boat. Acording to the wiki an a12 can rev at 5500 rpm all day and I think with an oil cooler and sufficient coolingi can bring that up to atleast 6000 rpm. A stock a12 is rated at
69hp@6000 rpm and has about 95nm of torque. Looking at 60hp outboards they seem to have around the same hp and torque rating as a a12. Now all I have been researching tells me that the a12 can be used as a marine engine. Am I missing something? I know this is a car forum but im hoping there might be someone who can shed some light. My plans are to supercharge and turbo charge a stock a12 with with a oval port head
