23'

Greetings dknesich, and welcome aboard.

I dont have the same set-up but I think that's about as good as its gonna get with those motors. That's over 800 lbs for 230 hp and the drag of 2 lowers. Your RPMs are where they should be, but I think due to gear ratio differences the small props of the Yammies have less blade area than say the Suzuki 115s and cannot offer as much locomotion, er, propulsion. I'd get the biggest diameter props that motor can handle and reduce the pitch to stay in your desired RPM range.

But realistically, 36 mph or so ain't bad. If those motors aren't on a flotation bracket that probably hurts a bit. I presume you have trim tabs. If not, getting some big ones would be my first recommendation. That will certainly help lower your planing speed. With that power to weight I would be surprised if you can stay on plane at 20 mph.

I also doubt you can plane using only one motor.

I think that hull favors more power. If those Yammies are pretty new I'd be tempted to sell em and look for single good 250 HPDI or the like with the proceeds.

Good luck and enjoy your new ride.
