Need Prop assistance

[Garry Gaede]

I have a 94 Mariah Talari Z 210, 4.3L Alpha 1. The hull is fiberglass about 20.83' / 96" wide and approx 3,000 lbs. WOT approx 4400 to 4800. I am looking to find the best prop for speed and pulling tubes. Currently i have an issue that when I throttle it take approx 3 to 4 min to finally get to 23 to 29 MPH that top speed. I would like to get at least 35 to 40 if possible.

Can anyone assist me. looking for proper diameter and pitch.

Re: Need Prop assistance

What pitch prop do you have now?

Good answers will require the drive ratio, prop pitch, WOT speed and WOT rpm at that speed.

Your descripiton of 3 to 4 minutes to hit top speed is indicative of engine problems, when was the last tuneup? Has the engine compression been checked lately?
