NOTE:

Next to selecting an outboard,choosing the right propeller is one of the most important purchasing decisions a boater can make.The type,size and design of your propeller have a direct impact on acceleration,top speed,fuel consumption and even engine life.Select a propeller that will allow the engine to reach the middle or upper half of the operating range at full throttle with the max. boatload.Generally,chose a larger pitch propeller for a smaller operating load and a smaller pitch propeller for a heavier load.If you carry loads that vary widely,chose the propeller that lets the engine run in the proper range for your max. load but rememberthat you may need to reduceyour throttle setting to stay within the recommended engine speed range when carrying lighter loads.
