Suzuki 30, I was trying to keep it light.

Is that a 4 blade prop? I tried several props and because the boat is so light I found that a 3 blade is much faster and the boat doesn't require the lift of the 4 blade. Just food for thought. I would think you should be able to hit 30 mph especially because you built light.

great job.

It’s just the stock aluminum prop. I’d like to try another one. I messed up when I mounted the Jack plate and the engine sits too low. The cavitation plate is about 2” below the hull with it jacked all the way up. It should help when I get that straightened out.

If it helps I built mine heavy, ( Livewell, trolling motor, poling platfoam, with a 50 hp). My cavitation plate is about 1.5 inch above the bottom and I'm thinking of going one more hole up. Also, the transom as designed (or at least how I built it) was too steep. I had to install motor shims to get more negative trim.

The negative trim is good. I definitely need to get it lifted though.

Chuf, when you tried your 4 blade props were there pitch size at least 2" smaller than your 3-blade pitch. The most in speed you should lose is 2-3 mph. Edd if you would like I would be glad to work up a new prop size for you if you would like. Tom
