That motor takes the same as the 2000 I've got, 15 spline.

This was the 14x19ss and 14.8x17al fuel burn numbers.
5000rpm-42mph-19.5gph-2.15mpg
3800rpm-30mph-10.5gph-2.85mpg
1250rpm-5mph - 2.5gph -2.0mpg

I'm not sure what the WOT rpm's are supposed to be for that engine. I just know I never achieved them with these two props.

So, it turns out that the old motor I had (91 Rude 200) had a 4 blade prop on it. It says 15x16 on it. I assume that is a 15" blade with a 16 degree pitch!?! If this is the case, I plan on trying it out over this next weekend and see how it performs.

btw, using the 21p prop Saturday I was running 39 mph (gps) at 4200rpm. Seems as though the engine had lots more in it but I didn't push things. Absolutely ran like a charm though.

Any suggestions on a prop for my V-21 200 Yamaha 2-stroke? I'm new to the serious boating stuff been aroud them all my life now I'm paying attention. The aluminum prop that came with has no stamp on it indicating what pitch or size it is. I hit 48 Mph on the GPS full out if the tack was right it was 5000Rpm and 33 Mph at 4000 Rpm. Does this sound right or not . I want to get to try and find a SS one I'll be doing day trips out to some Islands mostly. I'll be going out with my father tomorrow to see if the tack is on or not hope fully I can pin down some more accurate info.
