Level out your trim tabs and drive with the keel and use a WWH 7016 3 blade prop. If you are using your stock exhaust pipe and exhaust flange, you will need to open up those babies out. Set your exhaust flange onto the exhaust port and look through the hole, dremel or file off the excess material off the flange so that both holes match up, then do the same for pipe opening. Dremel off the excess weld to open it up a bit or replace your pipe with a 7/8" SS header and pipe.

What speed you get out of this setup?

With the cleaned up header and flange on stock pipe using the M5 bolt on with 7016 3 blade prop = mid 40's
With Arrow Shark WTC pipe and flange that has been opened up to the M5 exhaust port = low 50's

I'm waiting on a 2" 90* header to test with another Arrow Shark pipe = I will post results here!

Im using the pro wet pipe from WHH and its twice as fast as the rio stock pipe and header and not near as much trouble as a dry pipe heat is not our friend ...wild
