-Boat is 16'9, flat bottom tunnel 6ft wide.
-50hp tohasu tldi
-Total weight boat/motor/batteries/gas, loaded with 2 passengers/gear/full livewell: 1500lbs.
-Max motor rpm 5850
-Current prop: powertech SS 3 blade 12 pitch, cupped.
-Motor is mounted high, with a little trim the prop is on the tunnel, kinda like a manual jack plate
Boat runs WOT 28mph, rpm 5800. Prop bites good and I can trim almost all the way out of the water before it starts to slip. Hole shot is good.
My problem is if I add more weight, like an extra passenger, it will take forever to plane.
Will a 4 blade prop fix this, or is this a HP problem?
