I know this is a difficult question to answer, but I'm hoping some of you with experience swapping props can help. I have never deviated from factory props before, and my boat neighbor gave me a set to try out, because on my boat, I spin around 3600rpm and run around 29MPH - he gets 29MPH at 3200 rpm.. and who doesnt want to save gas these days!?

Here are my specs.

1989 Four Winns 285 Vista ('29, 10' beam) appx. 10K pounds - Twin OMC Cobra 5.7/350 230HP.

29MPH is good sea conditions (2-3' waves, 10-15mph wind) @ 3600 RPM

15"x17p SS props.

My boat neighbor has a spare set of 14x20 props, but that are for a Merc. Alpha-1 drive (not sure if I can borrow these or not... that is the first question)

Also, looking for suggestions on the best props for this configuration. I'm more concerned about fuel econemy over hole-shot. I don't mind tabbing down to get on plane.

Any suggestions will be greatly appreciated!
