Prop Advice?

[JohnR]

I have a 24 Trophy on my Starliner running 68 mph at 5800 wwith two people and no bow cover. With the cover and me solo it runs 69.5 with a full tank and the same prop turning closer to 6000. It's a decent all around prop but I'd like a bit more top end. Someone is interested in trading his 26 Trophy straight up for mine. I'm concerned this might be a bit too much prop to turn. My plan is to get a 21 or 22 to use for skiing and cruising with the family and run something like this 26 for when I'm going out to play. Any input on this?

Thanks.

John
