Need help figuring out what prop to run!
28' single engine #5 setup
Has anyone ever ran a 28 ' magnum style hull with a SSM#5 drive on a singe engine making big HP ? If so where do I start with the prop? The engine is a 540 ci BBC W/twin turbos running 10-15 lbs of boost. The prop shaft centerline to bottom of keel is 1 1/2" the boat is setup with K-Plane tabs and full hydraulic steering. Boat weighs in at 4,500 lbs and the engine is in the 1,100 hp range. drive ratio is 1.34 engine RPM is 5,800-6,000 with rev limit at 6,500 I have discovered that the props for this drive can get rather pricey so I'd like to see if anyone has a good idea of where to start. I'm going to try a merc 5 blade cleaver 16% rake 18" dia 31 pitch just to see what it does. Any impute here would be great thanks
