Semi Cleaver

14 on a stock 50 will turn right at 5700-5800. Sprinkle a little magic dust in that motor and it will turn that 14 about 6200. When I'm done porting a 50 Tohatsu, they normally turn a 15 pitch Yamaha 6200 loaded.. Tohatsu and Yamaha are not the same port mapping.

Danny, how do these props run on a tunnel? Will I need to add some cup to it?

Yes cup will be needed for a tunnel....the cleaver has little to no cup.

I thought that they come with slight cupping? Correct? I can run my Round Ear Blades 3/4 trim 35-37 MPH at 5500-5700 RPM. With the semi cleaver I'm guessing that prop will run right once trim angle puts ventalation plate and keel parrarell? I would like to run one before i spend $360+ because every time I've asked someone about props Yamaha semi cleaver is mentioned.

VERY light cup. Not anywhere near as much cup as for a round ear prop. Semi cleavers are designed to run surfaced, so they hold extremely well in a high application, such as a tunnel. The fastest marsh tunnels I have set up run with Yamaha semi cleavers on them, they sacrifice no hole shot.
