How to Choose the Best Boat Propeller

Every boat owner must understand that there is more to proper maintenance than just engine tuning and hull cleaning. One of those very critical components of boat maintenance also happens to be one of the most neglected, which is choosing the right propeller to optimize 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. However, a damaged or broken propeller is not the only reason for replacement. There are times when you just feel like your boat’s performance is not at par with what you are expecting.

Well, here’s rundown of the things you should consider in choosing a new propeller.

Possible Performance Issues

In case your boat seems sluggish in coming out of the hold or slow to get on a plane, it usually means you should consider replacing the propeller. The same thing goes for a boat with bad fuel economy.

Decide to Either 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. Hence, if the same engine is over revving, use a propeller with more pitch.

Elevation Plus Weight

If you own a small boat and you traverse through high elevation, you might experience a reduced engine performance due to the lack of power caused by reduced oxygen concentration; but there’s a way to compensate by means of bringing along a second propeller with reduced pitch. The advantage of a second propeller with reduced pitch is that you allow the boat engine to retain its performance by achieving the correct RPM.

With regards to weight, you should know that your boat carries a lot of heavy stuff, suggesting that the original propeller may have 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. You actually have utmost versatility since you can carry two complete propellers or perhaps two modular propellers with different pitches in order to customize the pitch in matching a wide range of varying conditions.

But just like buying any other parts or components of your boat, it is important that you do extensive research first. The last thing you want is purchasing a propeller that doesn’t fit your needs or perhaps get one from a manufacturer that makes substandard quality.
