I just purchased a 20' sutphen with 225 merc. optimax / what prop should I be running on her???

Depends on what you want. Acceleration? Hole shot? Top speed? All of the above? You will have to consider trade-offs as different props are designed to do different things. It would also be helpeful to know what type of prop you are running now, top speed and RPM.

What prop is on it now? What pitch? Have you had it out on the water? What was the maximum R.P.M. at wide open throttle, trimmed out? Ed

Have not run the Boat yet / having it repainted now / Looking for an all around prop!! How do I know whats on there now? Is it stamped on the Prop?

Hey Ed / Not sure on all of the above , will check on the prop today! Never ran her yet, bringing her to the paint shop this weekand, John

Don't waste your time and bucks like I did at first. Call Throttle Up (877-842-6855) and Julie or Matt can help you get where you want to be.

Speak to Sutphen directly, they are the ones to answer this question. On their recommendation I run a modified 25 Mirage on my 20 I/O and have yet to find a better prop for that boat and I've tried a few.
Is the 30 sold yet?

Can you give us some specifics, please.

What is the year of the hull?
Motor size and year?
Current propeller make and pitch?
WOT RPM and MPH (gps)?
What is your goal?

With a little information we should be able to get you dialed in!
