Many factors figure in to being able to plane a load.Prop pitch is often the culprit.If you are sure the motor is sound and properly tuned then
motor trim and prop pitch is the place to check.Hull weight and design play a big factor as well.If you trim the motor in (Prop closer to the boat) it will plane easier but may push the bow down.Start with it all the way in and trim out to the best overall performance.Think of the prop as a transmission stuck in one gear. Higher numerical pitch generally give better top end.
and less power (hole shot).Generally less pitch gives More power and less top end. When changing pitch you must stay within the motors reccomended maximum RPM range.Neither too high nor too low.A tachometer is a must when selecting prop size.Tiny tach makes an easy too install inexpensive tach.They have a web site.
