-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?

do you have a jack plate?

when loaded with extra passenger a jack plate will move the center of gravity
farther back allowing for better bow lift and reduce the prop slip.

may i suggest a 4" rapid jack.

call if you'd like to talk about or purchase one.

thanks
