I'll give Eric a call.

Thanks all
I'm not sure what the wide open throttle rpm's should be for your engine, but I would assume 4800-5200 rpms.
You said @ 4200 rpms you are at 36 mph. Another 800 rpms should give you more than 4 mph I would think. See what Eric says, but maybe the 14.25 X 14.5 prop might work better for you (but it will raise your rpms at wakeboarding and skiing speeds)
I was njskier on here.
