Re: 4.3 in barrelback 20

A few pics moving the boat, gauges that just came in, and fitting the tiller on the rudder post hence why the rudder is in before the shafting..

Re: 4.3 in barrelback 20

Wefisurf I think you're looking at a 12x12 prop. Maybe get between 45-48 mph. At those RPMs, 12" diameter is about the max. After that you'll probably have blade tip cavitation. Then you play with pitch. I'm not a pro. Just my thoughts. Bill Thanks so much bill. I was torn between 12x12 or 12x...

What is the WOT rpm? And what gear ratio? With that I can make guess at the prop.

Hey thanks,
Apparently it's 4400-4800 with a 1:1 borgwarner

4.3 in barrelback 20

Just want to know how this boat will perform with a 4.3lt vortex mercruiser in a 20' version of this boat.
I have her all ready just need to drop on power..
Is it worth spending the extra on a v8?

Thanks for any input:)
