Sea Craft 23 twin yamaha 115's performane numbers

Hi, anyone out there with this combination that can share his performance numbers, engine height and propellers? I just bought the engines but I think that can improve top end and cruising speed a little more. Any information would be gladly appreciated.

I bet WOT is 35-38MPH and good hole shot. Cruise at 23-25MPH. I run a 4 blade 15" pitch on a F100 on a 20 footer. It has a different gearcase ratio 2.31:1 versus 2.15:1. I suspect you will be happy with that pitch prop. But that's a lot of engine weight on the transom.

25.5 kts cruise at 4k, 38.5 kts top end 5950 rpm's. About 2.6-2.8mpg at cruise.
These are real world numbers on a 23cc with a radar arch and Bimini up full transom
and bracket.

I was running 23" Suzuki aluminum which were ok but Tom Clark
hooked me up with 22" stainless props and they are perfect. Now runs
real flat and she gets on plane great if there are 2-7 people on board.
