Repowering my 2012 721 with a new pro xs 4 stroke. What are most folks running for a prop with this setup. Ran a 26p fury on the 2 stroke, but I believe mercury is recommending something smaller with the 4 strokes.

What kind of rpms are you getting?
A 24 fury on a 4 stroke runs similar to a 25 on a 2 stroke. A 25 on a 4 stroke runs similar to a 26 on a 2 stroke. Overall my buddies with a 721 and the 4 stroke like the 24 fury better in all conditions but the 25 fury was about 1 mph faster in cold weather light load.

What speeds are you getting with this set up at what RPM? Anyone using the plugs on the props?

I have a 2019 721 with 4S. Running a 24 3 blade fury with 10" atlas hydraulic. 3/4 tank of gas, tourney load with partner and his equipment I can run 74-76 with the right chop on the lake. I currently read off the analog gauge and it is close to being dimed out at 6k running that load and speeds. If I had to say i wouldn't doubt the RPMs are around 5850-6k. All my plugs have stayed in. Never had a reason/need to pull them. Performance is great on low and high end
