Currently setup with 6″ manual slide master jack plate flush. Have twin poles 4 lead acid batteries with a 24 pitch tempest plus with vent holes plugged. Prop slightly blows out as boat breaks over, rpm 5760 at 69 mph with full 33 gallons of fuel and gear. I tried to lower motor height to get rid of blow out but boat doesn’t have any lift and just plows the water. 23 pitch fury with vent holes plugged had 6000 rpm at 70 mph,but blow out was even worse had to feather gas to get it on pad. Any ideas or suggestions would be greatly appreciated.
