The Need for Aftermarket Boat Props
Those who are new to the leisure activity of boating may not be aware of one key fact about outboard propeller engines. In most cases, the propeller that ships with an outboard engine is a “stock” part and is not, in fact, the ideal propeller for every boat that may elect to include that particular type and model of outboard motor. Stock boat propellers such as these tend to be designed along “compromise” principles that will allow the motor to be used with a large number of different boats.
Depending on the hull and load that the motor must eventually contend with, however, these boat props may range in performance from average to unsatisfactory. The solution to this problem is to look at the range and variety of aftermarket boat propellers instead. Choosing the correct propeller for a specific boat and engine will allow the engine to run properly at its rated horsepower, which is usually marked clearly on the engine cover.
Outboard engines are supposed to be able to run at their maximum rated revolutions per minute – this situation creates peak efficiencies. The wrong propeller can cause an engine to run at an exceptionally high RPM. This leads to faster wear and tear on engine parts because it creates additional friction. Too few revolutions per minute are also inadvisable since it causes carbon build-up as well as poor fuel utilization. The right boat propeller, however, can help boaters to avoid both of these situations so that they can derive maximum use and pleasure out of their watercraft.
