I have a 2014 Yamaha 250 SHO on a Bumble Bee 200 Pro Sport. I'm currently running a Yamaha T-1 25P I'm getting 72.9 mph at 5900 RPMs with a quick hole shot. I'm considering a four blade as a back up prop for rough water. Anyone currently running a four blade on a 250 SHO or have any experience with this type set up? I would specifically like to know the prop and pitch. THANKS IN ADVANCE
