![]() ![]() The high five literature, for instance, states that you would want to choose a high five prop the same pitch as the one you're currently running assuming you're running correctly with that. The rated pitch is as closely related to how it actually performs as can be guessed, by the experts that designed it. Different areas of the blade have different actual pitches. Propellers, especially the higher performing stainless ones, are seldom a fixed pitch, but rather progressive pitched. Re: High five vs revolution-prop question The black max prop was the salesman's favorite because he had to dump it somewhere. Boat's full of folks that don't want to go fast anyway. I run a 24 pitch high five for fishing (racing with a fishing pole) and a 22 pitch for pulling skis and tubes. Just for reference, I'm running an XR4, which develops about 165 at the screw, and a 1.78:1 gearcase. It's very low with this prop, even surfacing it. Normally surfacing would kill an xr4 gearcase in a short while, because it is a light case and succumbs to tortional vibration. At full tilt, mine is about 25% above the surface, and she pulls real hard into the 60's. It's a high performance ride, running well above expectations. I run a high five on a XR4 150 on an 18' bass boat. Many good ones will as long as you pay for it and bring it back not having done any rototilling with it. It might be good to do some formal prop calculations, or see if you can hook up with a prop vendor that will let you try out a prop. If you're on the limitter all the time, you are too low in pitch. On yer boat, I don't think you'll lose enough top end to care. Once hooked up, it stays hooked up, even if it's half out of the water. ![]() When it hooks, all hell breaks loose, which is exactly what you want when you're pulling tubes and skiiers. It's a ventilated prop, so when you blast off, it gets a little loose, letting your engine spin up into the power range. I think you should get the 23 pitch high five, and I think you will really like it. Oh forgot.what am I mainly going to do with the boat, pull 3 tubes out the back with 3 adults in the boat but don't like loosing a good oll Daddy bow rider race with the next guy OR what about the Revolution 23? Or do you guys who "know" have a better idea.I am a good listener/reader High five 23 thinking the extra 2 blades over my allum 3 blade and smart tabs the hole shot may be even better. But with my max rpm so easily achieved I was thinking going a step faster. I was going to just order a High five 21. With this info my question is.PROP purchase time. My speedo reads 50 mph (a little more if the boat is light a little less when 6 or 8 people) My hole shot is pretty decent with a tuber and 2 adults in the boat but is horible with much more after that.is this normal? I do expect to install smart tabs in the spring to help the hole shot. I can easily cruise and hit 4950 rpm with the annoying alarm, so I have to back the throttle off untill the alarm quits and rpms drop. It is fuel injected so I am rpm limited and have a warning alarm going off at 4950 rpm. ![]() A alluminum merc 14.25" 3 blade 21P with a final drive of 1:81 I purchased it new but my sales person did me a "favor" and installed the prop he would have wanted on it if it were his I left the jet boat seen a few years back and just purchased a 2009 Rinker 192 Captiva with a 4.3 V6 Merc MPI 220 hp. ![]()
