19M prop ??

[CaptJ]

I have a 19 pitch on my '99 200 yamaha as well (bolted onto my '89 V-20 Cuddy). I am seeing the same numbers. 49-50mph with the motor trimmed and turning about 5000-5100 rpms. I have been thinking about trying a 17 pitch to get more rpms out of it. Any thoughts out there?

I have a stainless 17 from my original '89 225 yamaha, when I put it on and trim her up she cavitates so I am thinking of possibly having it cupped some more.
