I have the PT 4 blade srt on my 20hp Tohatsu on a small tunnel like that. Heavily cupped by Jack Foreman. Its ok but looking to go up to a 12P 3blade and have Jack pound that out. It kind of depends what you are trying to do. I'm trying to go as shallow as I possibly can and get the skeg even with the bottom of the boat w/o losing grip. If you are doing that too, I would first consider getting a anti-ventilation plate like the stiffy. Something that extends forward towards the tunnel to grab more water. That alone will allow it to run much higher without slipping.

Yes, I know Louie and Jack. I deal with Jack because he’s close, specializes in shallow props and builds a badass prop.

thank you, yes you correct, trying to go skinny. but we have to cover water/ distance , so that why went to the 3 Blade. I also agree Cav plate is required, Stiffy $$$and the Cougar Marine out of san Benito,TX are the two that was under consideration.

I plan to run the three blade prop for a while, I am going to purchase SS 3 blade 9.25'x 9P but your going to 12 P WOW!
this 20 Suz, when I brought had 400 HRs I put about 70 in a year . I just had a broke down ie carbon build up on the rings, but think its was due low RPM 1000 to 4000 rpm with the 4 blade 50 %
now I running ring free yamalube
i would like keep up with your progress, maybe Foreman the answer!

I'm selling a cougar one right now. It is too wide for that diameter prop in my case. Happy to sell it to you if you want it. The Stiffy is narrower and I think better for this small of a prop. I would def keep a three blade and cup the S$%# out of it. I'm going 12 because it will be a 3 blade and Jack told me too. He knows more about props than I will ever know. The plate is what feeds the water to the prop. Without both, it cant run right.
