Tested the prop today I went with the 15 pitch motor is mounted with tip of bobs nose cone at the top of the tunnel there was some prop slipping until tunnel was primed hammer down the prop grab like no other prop I’ve had but 5100 rpm was the best I got boat porpoise with any trim 20lbs of water pressure not sure what my best mph was I didn’t have a gps with me any suggestions if a cavitation plate would help with holeshot

Don’t hesitate to try the 4-blade PFS if you need a bit more holeshot super skinny, or if you need to lift the stern.

I had to add 12x8 fixed trim tabs to stop porpoise issues, n adjust angles few times to get it trimmed. Still too much pitch with prop, need to be 5600 / 6000.

I still don’t understand why you guys don’t confide in a prop guy instead of dicking around testing 3-4 props and ending up with mediocre results. A good one will get you the right prop usually the first shot and then fine tune to get maximum efficiency.

Not all of us want to go to jack foreman and there’s only thousands of different prop shops out there finding a good one is trial and error in its self

Who said anything about Foreman? All I’m saying is you could narrow down props to try if you talked to a local prop shop if they have any around your area.

I understand what your saying but if you ask anybody on any of these microskiff,2cool fishing etc they all point to foreman props over here in FL any prop shop I’ve dealt with look at you a little funny when you say anything about triple cup or excessive engine height they don’t specialize in the extreme shallow water props and I would like to deal local (FL) I went with Powertech because about all prop shops can work on them it take a more specific prop guy to work on the custom props Foreman,Baumann etc if anyone can point the way to a prop shop in FL that is very knowledgeable about tunnel skiff prop sent the info please

Since you brought it up again...There’s a reason Foreman comes up when people ask about propping a tunnel hull. He also sells stock Powertech props and believe it or not he designed several of the props they sell as “shelf props”. I’ve been to Florida, re-rigged boats bought there and know why they look funny when you mention triple cupped props or raising the motor high. It’s because (from what I’ve seen) they don’t know Jack about properly rigging a tunnel hull to run the way it was intended.
Sorry I chimed in and tried to help. I’ll leave you to your run-on sentences and search for the perfect shelf prop.

That’s probably the best reply you’ve given now back to my question does anybody have any experiences with a cougar marine cavitation plate?
