So far, the first run with the new 6" jackplate net it me 65.4 @5300 RPM's.
2009 E-tec 150HO, 4" below the pad, 24" Raker II, water temp 70, air temp 69, 1/4 fuel, lots of fishing gear, empty livewells, little chop, tons of water press 25+ lbs.
i'll be bumping up the JP a little at time, the speed was a bit better then i thought, i'm not sure how much more i can squeez out it, it was 62.3 before.
is this a good speed for this boat?
got my old 273 up to 69.8.
