I have a 22 Classic with a 260 and Alpha1. I am not looking to tear up the drive, but does any one have a prop recommendation. I am currently running a Vengence 21P and it sometimes feels like it is cavitating...
Thx

Looks like too much torque...flipped the boat over.

Please give us a little more about the performance of your boat.
What's the drive ratio? 1.5 or ?
I'm thinking you would like the WOT RPM to be about 4600.
I tested a number of props and liked the Turbo 1 3 blade and Merc Rev 4 4 blade the best.
The 3 blade will be 1-2mph faster on top, but the 4 blade will be faster mid range and the boat will likely handle easier...
Thank you, Patrick

neweays33. Posting on an I Pad?
mine flips my pics upside down all the time...D
the drive is a 1.5. Motor is all stock 4 inch exhaust. The motor will go to 5200 wot. Looking for some better midrange
I would say try a 23p mirage 3 blade I ran that on my 18 it was great and I still have it in great shape.
does the Vengeance have vent holes? if so, you should plug those first and try it again

looks like the 23 Mirage will be the next step...

Newsday33 where you from I hope your close I would give my prop for testing.I now how expensive it can get, I'm sure we all now.
5200RPM with 21P in a 260 Merc powered 22 is definitely slipping. I wouldn't throw a 23 on just yet. I got a mirage 21P you could try out to base line it. I am just a little more north of you if your interested My Minx topped out @4800 with the21p and the 350 Mag average speed was 58mph in Summer 60mph in spring and fall.
machinist ,bore it deeper,ream it bigger, and lap it to a fine finish
