AquaCraft GrimRacer Precision Prop Balancer - Manual

WHY BALANCE AND SHARPEN YOUR PROPELLER?
Model boat propellers typically spin at the same RPM as the motor or engine. Any vibration that comes from the propeller can
rob your boat of both power and speed. It can also ruin electronics and even break metal parts. It is always best to balance your
propellers. Likewise a dull propeller can upset the handing of the boat.
