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.

Outboard motor shaft length for pontoon boat. If you have a 16-foot-long pontoon boat you can use a 25-horsepower engine to cruise around but if your pontoon boat is 22 feet long youll need an engine that has at least 150 horsepower in order to get any decent speed. For 16-foot boats getting a 25HP motor should do the trick. 1 Multiply the overall length of your boat in feet by its widest beam at the stern excluding any Fins and or Shear 2 Locate that value on.

Any boat longer than 20 feet shouldnt have less than a 115HP motor. Long time lurker first time poster. Selecting the right length may depend on your necessities but the most common for pontoon boats is.

Long shaft vs 20 inch shaft motor on Pontoon. The outboard motor shaft length and transom length need to match in order for the motor to be at the right height while it is operating in the water. The transom is the back of the boat where the motor is hung.

Other shaft lengths exist. The truth is that the outboard motor shaft length for your pontoon boat depends majorly on your pontoons engine size. If it measures 15 or with in a inch of that you will need a short shaft outboard.

Most the pontoons I have seen use a 20 inch shaft. Small motors built for sailboats might come in a unique configuration with an extremely long shaft since these are mounted higher off the water. The outboard shaft length is the vertical distance between the top of the mounting clamp bracket and the bottom of the cavitation plate aka the ventilation plate.

For the Minn Kota add 20 inches while for the MotorGuide add another 16 inches choose the nearest measurement. The Outboard Industry Association OIA has recommended this formula. The Evinrude Pontoon Series already includes 90- 115- and 150-hp models.
