  I have a Yamaha 225 Vmax 01 model, and it has a 27M prop on it. It runs great, good hole shot and top end, but I was jus wondering if there is any other props I could run for better performance. The motor is on a zx225.. Any info would be greatly appreciated..

It’s hard to say. What is the max rpm your motor can turn, and how many rpms is your motor turning with the current prop?

I usually dont run it no harder than 5600 rpm. Itl do more but at that range n trim im run’n mid 70’s area…

Reason I ask most outboard motors are designed for the buzzer to go off at like 6200 rpm. Rule of thumb is the bigger the pitch the the faster it will run but you loose on the hole shot and you will turn less rpms and the less pitch the better the hole shot and less mph and more rpm. But that’s not always the case bc you have to take in consideration the the diameter of the prop as well. If you could find a bigger pitch with less diameter you might gain on both mph and hole shot.

That is the standard prop for your motor/boat, you aren’t going to gain anything tremendous by switching.. maybe 1-3mph top end, or a 2 second faster holeshot to WOT.

Alot of factors to consider here. Do you have a jackplate? What is you motor height, prop to pad? How heavy do you load your boat? Are you looking for more top end or better hole shot? If your running in the 70s with the prop you have and your only at 5600 rpms, I think your set right where you should be.

Yes it is on a jkplate, jus a manual slidemaster… Idk the height, and I do carry tourny gear all the time. Its runs great for me now, I was jus curious on anyother props. Itl sure keep up an outrun plenty of people if I want it to, but I was jus wonderin what anyone else has on their yamahas. What is recomended rpms for this motor? An whats the “comfort” range anybody runs?

Recommended RPM will be in your manual.

I run my merc at 4000 unless I’m in a hurry to get somewhere. 4000 is right at 3/4 throttle for me.

Your max rpm should be in the manuel, if not you should be able to find it on Yamahas website. I have a little 150 vmax carbed motor. The max recommended rpm is 5500-5700. When Im running balls out Im at 6000 rpm. I need to go to a 25 pitch,but the wallet isnt letting me do that right now.

Thanks for the info. Im the 3rd ownr of the boat n dont have a manual, but some of my friends say 5500 5600 is bout rite. Hit up some tournys that’ll pay for that 25p. Lol. Again thanks alot.

there are a lot of variables in this question… what type of boat is it?how much setback is the jackplate?prop to pad height?
you may very well have to best prop for your boat,but a little setup and adjustments will get the best out of your boat…

the smaller the setback on the jackplate,the better the holeshot,but slower overall…vice versa on more setback…if your lower is too far down,
its just more drag and slowing you down…you need to measure these before you can get any info on if you have
the right prop or not,or any gains in performance to be had…
