A propeller shaft, or a drive shaft, transmits torque and rotation from your model boat’s motor to the propellers, meaning they must be sturdy, strong and durable enough to withstand the force of the motor and weight of the model boat, as well as be erosion proof, and protected against damage. We offer a range of sizes in order to suit any model boat you may be building, so you can find the perfect propeller shaft for your design, without having to pick a less lightweight version, or a size that might be too weak for the size of your boat and engine.
