After trying a few props our results are the same as Mrwalleye.
I decided to experiment with a jack plate and in the right conditions I got 62.8 out of it. I still have 3 more props to try out this year. On the average I will run 60-60.5 fully loaded.
This hull was not set up for the best top end as when you are WOT and trimmed out there still is a lot of boat in the water compared to the old ZX2050. But the rough water ride is night and day
