Horsepower, hp, is a measurement of energy. One unit of horsepower is the same as the amount of energy or power needed to lift 550 lbs. 1 ft. in 1 sec. Usually this is used in regard to engines or motors. In the situation of pontoon boats, it is a measurement on the engine that helps us easily say how powerful specific engines are. The engine on a small metal fishing boat may only be 10 hp to 20 hp while a high quality speedboat may have an engine with 500 hp. Theoretically, the higher the horsepower, the easier it is for your engine to push your boat.
All boats are different, pontoons included. Because of this, each boat has a maximum horsepower limit that cannot be safely exceeded. If you go over the allowed limit, the coast guard or police can stop you from putting your boat in the lake. They DO check! But going over the limit in horsepower may not be necessary. Most boats have a more than generous range in what the horsepower can be handled safely. If you really want more horsepower that your boat says it can handle, than you may want to consider buying a boat that can handle such a heavy duty engine.
When all boats are first made, pontoons included, and are being full scale tested, they are used with a variety of different engines starting from low horsepower engines and then they increase the engine horsepower until they find the limit that the boat cannot handle safely. They also would test to see the boat’s performance with specific engines. Then with an accurate evaluation of each engine, they would decide what hp the boat performed the best at and what it performed the safest at. With those limits set, they choose a limit to rate the boat for.
