Selecting the Right Propeller for your Boat
Every boat owner must understand that there is more to proper maintenance than just engine tuning and hull cleaning. 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.
The choice of boat propeller primarily depends on how you plan on using your boat and what the current performance is. Also, you must be reminded that a propeller that is already in pretty bad shape needs to be replaced right away. But then again, a damaged or malfunctioning propeller is not the only reason why you seek replacement. There are times when you just feel like your boat’s performance is not at par with what you are expecting.
Let us take a look at the things you ought to consider in choosing a new boat propeller.
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 must be considered if your boat seeps too much fuel.
Pitch Up or Pitch Down
You probably already know by now that pitch and engine RPMs are very much related, but inversely. Just to be clear, increasing the pitch will decrease engine RPM, while decreasing it increases the RPM. In the event that your engine is suffering from under revving, the best option is to buy a propeller with less pitch. 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. Fitting a backup propeller with reduced pitch allows your engine to attain the right RPM and perform optimally.
Know that when it comes to weight, your boat carries a lot of heavy things, which translates to the possibility that the original or default propeller has too much pitch in it, leading to lower 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. It is possible to customize your propeller’s pitch in order to match different conditions, or perhaps you can carry two complete propellers or a couple of modular propellers with different pitches.
But just like buying any other parts or components of your boat, it is important that you do extensive research first. You certainly do not want to end up buying the wrong propeller or getting one from an unknown manufacturer with questionable reputation.
