Repowered my 19 ft center consil Seaway (Eastern Hull Maine Built). Now I'm trying to figure out the right Prop. I have tried 2 so far. First was 13 1/2 X 17. WOT was 5200rpm max 28knts . Second Prop was 13 5/8 X14 with WOT was 6200 at 27knts. Would like to get 30Knts out of the boat. any Ideas. Thanks for looking.

The engine is rated for between 5000 and 6000 rpm . The Performance bulletin on the Yamaha site has that engine with a boat my size doing a max of 36 knts
