Motor height adjustment and Proper prop for speed

[dryhorn2]

Anybody on here good at setting up jackplate, motor and prop for peak performance ? Please PM me so I can give you my setup and see what you think...

Get rid of the jackplate, go back to what was on the motor when you bought it. 60 mph is fast enough. I will slow down and let you keep up with me. emoEnforce emoPoke emoTongue emoBigsmile emoBigsmile

You need to pm bumblebeekid. He'll get you set up the way you need. I had to take my motor up as high as it would go, Triton's apparently like the motor almost out of the water.

What boat and motor. I have owned several different rigs.

 

[dryhorn2]

95 procraft v180b with mariner 150, 23 tempest prop, 3 1/4" below pad.

Usually 3 to 3 1/2" below the pad is a good place to start. You should have a water pressure gage because as you go up with the engine you can cook a power head quick if you lose water pressure. Go up until you start losing speed or your water pressure drops below a safe number. Don't go by your speedometer for this, as they are not only inaccurate, but as you change your engine height and trim setting they will read different. That is why you can't even use the speedometer as a reference to tell if you are going faster or not. A GPS or radar gun is the only accurate way to do it. I would think that a 23p prop should be about right for your rig, but all 23p props are not created equal! You want to find the sweet spot that gives you the highest speed with acceptable water pressure. Now if you find that you run into the rev limiter while you still have good water pressure, then you need to go to a 24p or maybe even a 25p prop. If you max out your speed with good water pressure and are not within a few hundred rpms of your engine WOT redline then you are overpropped and need to drop down an inch or so in pitch. It just takes a lot of trial and error. By the way, don't make the mistake of setting your boat up for peak performance with only yourself and a very light load in the relatively cool days of spring. If you do, then it will be a dog fully loaded in the dog days of summer. Feel free to PM me if you have any questions or if I can help in any way. Good luck and be careful. Don't drive faster than your comfort level.
