Prop question

[Captdj]

Have a 2001 23 SeaCraft and repowered with a 300 Suzuki (30 inch shaft no bracket) recently and looking to see if anyone has run the 16X20 with that set up?

I have asked and looked on other post here and THT and everyone seems to be turning the 16X18.5, but was curious if anyone has tried the 20 and what there numbers are.

The shop put the wrong prop on and gave me a 16X17. I noticed it too late, but they are making good and when they come to swap the gauge they are bringing the 18.5 that I asked for. The 17 is like a raped ape coming out of the hole shot, but I want a faster cruise and know I will pick up just a little with the 18.5 so was wondering about the 20.

Current numbers as of 2 days ago with 4 adults and 2 teenagers fuel of fuel no fishing gear were.
WOT- 6300-6400 46 MPH on GPS (RPMS mights hve been a touch higher but wasn't able to constant stare at them)
Cruise- 4600 31-33 MPH
4500 30-31 MPH
4400 29-30 MPH
Didn't pay attention to anything lower. I came from a 300 HPDI and i know I won't get those cruise numbers back of 40 MPH at 4000, but I enjoy the MPG savings of the new motor just would like to cruise a little faster.
