2019 920 ProXP 250 Merc ProXS 4s.
My thoughts, the 26p fury seems jacked up, its numbers are way off from the 24p and 25p. I bought the 26p used and have no info on it. With the lithium batteries removing about 175 lbs from the boat I think I should be running 79-81 mph.
I have to trim the max amount and still dont seem to get great lift, my theory is the removal of weight from the back (batteries) has the boat lighter but out of balance. Do most guys running a 920 need max trim for best top end speed?
Thinking about trying a 26p tempest which is supposed to lift better that a fury.
what prop to pad are most guys finding best on the 920?

the (#) is the Atlas setting that goes with said pad height on my boat.
Slip calculation using Mercury App, and 1.75 gear ratio, which I think is right but some of those numbers seem low.
