Just trying to stir up some conversation... Our 20' Chaparral came with a 15x16 and a 14.5x18 backup in the engine compartment (both 4 blade). I was surprised the top speed as configured was a little slow at around 40mph. Did a little googling and it appears that smaller pitch and bigger diameter would give better acceleration and lower top speed. I suppose that's good for wakeboarding.
The 15" prop is a bit worn and I like to run our the boat once a month instead of winterizing, so I went ahead and swapped to the backup.
Whatcha all think?
I'm guessing it will be a little slower to plane, but a higher top speed.
The one thing I'm curious about is how different the ride will be at wakeboard speed. The Chappy rides bow quite high at wakeboard speeds. I wish I could change it but I doubt the prop will make much difference.
