I have a TRX 19 with a 21 INCH Tempest Plus on a 200 Mercury 4 stroke and it just doesn't have much top end, is there anyone on here that's using a different prop with better result's. I'm only getting 64 for my top speed. The Stratos with the 200 E-TECH I had previously would run 70 plus. Thanks

Are you hitting the rev limiter? I would think you could run a 23 or 24, maybe a 25 but I am not at all familiar with the 4 strokes...

I bet you have one heck of a hole shot with a 21" pitch, though! When you report a boat performance issue, it's just babble until you also tell us the LOAD and the RPM, for starters. Engine height could also be an issue, but in your case, the 21" jumps out right away.

Do you know your engines max. operating RPM specification? That's the point you want to be at when running full throttle, no more, no less.

Yes it comes out of the hole great but I'll need to check the RPM'S, that's with a full tank of gas and two people. Thought I should get around 68 with it, though, thanks for your thought's.
