Do I have the correct Prop?

[Fishingaddiction]

I have a Ranger 681 with a 135 optimax that I have owned for the last 2 years. It came with a 23p stainless prop and I am wondering if that would be the correct prop for this setup? I have not had a problem getting it up to its max rpm of 5250 but just wondering if I could have better results with a different prop?

I'd move down to a 21 pitch that will give you about 400 rpms. Depending on the year of your opti is either can go up to 5600 or 5750 rpms.
