And you forgot on a low rpm engine to. I was wondering whom would bring that up. I will not disagree but lets see if we can get him to turn it up. to a 7500 rpm engine at 13 to 1 on race gas set up.

Actually I was waiting for someone else to dog me like he always does.

After realizing majority of boats use I'd give up a little power and look at the dual plane and go out and have fun. Not worth squeezing every bit of hp out of something that will not see WOT often and you can taylor the build around your needs. I've used dual planes for years and loved them. Again your CI gives you the flexibility without sacrificing a significant amount of power either way.
