Tips in Choosing the Ideal Boat Propeller
As an owner of a boat, you must realize that maintenance is more than just tuning the engine and keeping the hull clean. There is one part of maintenance that is so essential yet most boat owners don’t pay that much attention to it: choosing the right propeller for optimized performance.
For the most part, your choice of a new boat propeller will depend on its current performance as well as how you plan on using it. Keep in mind that if your propeller is damaged or in bad shape, you have to replace it right away. But then again, a damaged or malfunctioning propeller is not the only reason why you seek replacement. Sometimes, the reason may be as simple as the fact that you are not satisfied with your boat’s performance.
Well, here’s rundown of the things you should consider in choosing a new propeller.
Possible Performance Issues
If you observe that your boat struggles coming out of the hole or is very slow, it is high time to consider replacing the propeller. The same thing goes for a boat with bad fuel economy.
Pitch Up or Pitch Down
You probably already know by now that pitch and engine RPMs are very much related, but inversely. To be exact, when you increase the pitch, the engine RPM decreases; so when you decrease the pitch, the RPM increases. In case your engine is under revving, buying a boat propeller with less pitch makes the most sense. Obviously, you want a propeller with more pitch if the engine happens to be over revving.
Elevation and Weight
When it comes to elevation, some small boats suffer from producing less power in high altitudes, but you can address this problem by carrying with you a second propeller that has a reduced pitch. Doing so enables the engine to achieve the correct RPM and retain its normal performance.
When it comes to weight meanwhile, keep in mind that your boat houses a lot of heavy stuff inside, which means that its original propeller may be equipped with too much pitch, causing a low engine RPM. It is recommended that you equip your boat with two different propellers with varying pitches, considering the fact that you may need to change configurations from time to time. Your options include tailoring your propeller’s pitch to fit a wide range of conditions, or perhaps carry two complete propellers or two modular propellers equipped with different pitches.
Just like when you are buying other components or parts of your boat, it is imperative that you put in the effort and time to do some research first. You wouldn’t want to end up buying a propeller with substandard quality or from a manufacturer infamous for its lack of aftersales customer service.
