3 Reasons You Should Never Run Your Boat with a Bent Propeller

1. Unwanted Vibration

Propellers are designed to be perfectly balanced. The smallest bend will throw the propeller out of balance, creating an unwanted vibration. The vibration will make the ride uncomfortable and the experience less enjoyable. Even if there are no visible bends on the propellers' blades, if your propellers have even slightly touched sand or mud, they could have been thrown out of balance.

Repairing and balancing your propellers allows you to enjoy your boat with a smooth ride and peace of mind.

2. Decreased Boat Performance

Aside from unwanted vibration and an uncomfortable ride, your boat will not perform as well when the propellers are out of balance. Your boat’s engines may fail to reach their ideal RPM, resulting in reduced performance. You may suddenly notice that certain aspects of the boat’s performance, such fuel efficiency and speed, are now negatively affected. In turn your fuel expenditure may go up with each trip.

3. Cause Serious Damage to Your Vessel

Having a bent propeller can cause damage to other parts of your boat, including the engine, drive shaft, cutlass bearing, and transmission. The cost of repair, on top of your propeller repair could be tens of thousands of dollars. If you can’t turn your engines up to full RPM, the motors could overload and burn up resulting in very costly repairs. The slightest vibration (even the ones you don’t feel) could wear out your boat’s cutlass bearings, crack your drive shafts, or result in loose propeller nuts and one or both propellers could fall off, even with a cotter pin, as they can be overpowered.

Propeller repair is relatively inexpensive compared to the other repair costs that can arise when the problem is not promptly addressed.
