I repowered my 1983 22' Revenge Cuddy with 2000 Yamaha 200 OX66. Finally got out for water test last week. Very impressed with power compared with 1983 Rude 175. Performance is great, 43 WOT on gps, great hole shot, and very responsive. The motor came with Yamaha stainless prop with number 7M stamped on exterior of prop. It probably has other numbers inside hub. RPM's at WOT were 5100 and playing with trim got up to 5300. Book states 5500 is where I should be. Is it worth playing with different props? What could I expect to see with a change?

John, thats a 17p prop & your dialed in pretty close.
I'd leave it alone.
Your only 200 rpm from max & 1 inch more or less of pitch wont change much at all.
I would concider raising the engine 1 set of holes, that will boost your rpms about 1 - 200 rpms with the same prop your now using.
If your engine is mounted all the way down at it's lowest setting or highest set of holes, I'd raise it at least 1 more set of holes & maybe 2 sets.

I agree with Sal. I would leave everything alone. 43 MPH at WOT with a 200 is very good. Your engine's WOT range is 4500 to 5500 and ideally you want to be on the high half of that range, which you are.

Raise it and leave prop alone.....takes 15 minutes using your tongue jack.

It is mounted 2nd hole from the bottom now. I did a couple high speed turns and it held very good. I may try to raise it to bottom set. Thanks for the replies.

John, I don't think that standard Yamaha prop will hang on if you raise her to the bottom set of holes.
You may need to go to a performance prop which will hang on much better than the stock s/s Yamaha prop.
If your already up that high, I don't think you should go any higher.
Merc props also fit that engine.
If you know a prop guy, try & borrow a 15p thats been cupped, that should be equal to a 16p & you would have more low end power, less blow-out, & might even pick up a couple mph on the top end.
That would allow your engine to reach it's maximum rpms.
I'm just thinking out loud trying to tweek a few mph more out of your rig, but your so close now......it's your call.

Thanks for the input Sal. I think I will leave it alone. I don't plan on running that fast anyway and the hole shot is great now. I may look at putting some tabs on eventually. It seems to have a slight list depending on wind direction and direction of travel. Need to save cash now so I can go fishing...season is upon us!!
