Pontoon boats can come in all shapes and sizes.

Outboard motor mounting height on pontoon boats. Theres no one size fits all type of motor for a pontoon boat. However the motor should not be raised more than 5 inches above the standard position. My understanding is most pontoons need a 20.

In fact unless you have a bunch of power say 100 hp or more mounting full down is the best setup. You need somebody else to drive the boat while you look at the motor height. Any boat longer than 20 feet shouldnt have less than a 115HP motor.

The size of your boat. Turns out some boat builders are letting transom height get closer to 21 inches or 26 inches. Pontoons are a different breed when it comes to speed because its a displacement hull instead of a plaining hull its brute power to shove it through the water.

My motor was mounted on the top hole by the dealer and I moved it up two holes gained 300 RPM and a couple MPH. The Evinrude Pontoon Series already includes 90- 115- and 150-hp models. Industry standards dictate that for short shaft engines the transom height should be 15.

Mounting height - cav plate anywhere from even with hull bottom to about 2 -3 above. However the standard recommendation is that for every 8-10 inches distance between the propeller and the transom the outboard motor should be elevated by an inch. Porpoising - in some cases trim tabs the best and final solution plus you get the added benefits of.

This doesnt necessarily mean that smaller engines will suck. BRP recently announced the addition of a fourth model to its line of Evinrude E-TEC Pontoon Series outboards designed specifically for pontoon boats a 13-liter triple-cylinder motor rated at 65 horsepower which will be available early this spring. I mounted the motor so the ventilation plate is in line with the bottom of the middle pontoon.
