Tips in Choosing the Ideal Boat Propeller
If you own a boat, you should know that there is more to maintenance than just cleaning the hull and keeping the engine tuned. 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.
In most instances, the choice you make on a new boat propeller depends largely on two things: its current performance and 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 that is not the only reason why you’re looking for a new propeller. 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
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 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. To be exact, when you increase the pitch, the engine RPM decreases; so when you decrease the pitch, the RPM increases. In the event that your engine is suffering from under revving, the best option is to buy a propeller with less pitch. So, if the same engine over revs, it means you should buy a propeller with more pitch instead.
Weight and Elevation
In case your small boat traverses in an elevated area where there is reduced concentrations of oxygen, there is a chance that the engine produces less power and eventually underperforms; if this happens, your best alternative is to bring a second propeller that comes with 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 better that you have two different propellers with different pitches since there are times when you need to change configurations. 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.
Similar to how you’re buying all other stuff for your boat, it is crucial that you study and do extensive research. You certainly do not want to end up buying the wrong propeller or getting one from an unknown manufacturer with questionable reputation.
