A Word About Prop Rotation
In Europe, the rotation or hand of a prop is determined by looking at the front of the boat and watching the prop turn. Here, in North America, prop rotation is decided by viewing the boat from the aft end. Therefore, hobbyists are continually confused by which prop to purchase, left hand or right hand.

A simple way to identify prop rotation is to do the following:
1. place a prop on a table and position one blade at "12 o'clock"
2. the edge of the blade that is closest to the table top is the leading edge
3. if the leading edge is on the right side of the prop, then the prop is right handed
4. this prop should turn clockwise to push the boat forward.
5. if the left edge of the prop is closest to the table top, it is a left handed prop and it should turn counterclockwise in order to push the boat forward.
6. determine the rotation of a prop in this manner instead of depending on markings on the prop itself or packaging it came in. This is important as the markings made by a European manufacturer will be the opposite to what you want.

Boats with twin props will be set up with the port or left hand side of the boat prop turning counterclockwise. When installing the corresponding motor, you may have to reverse the power wires to the motor to achieve a counterclockwise rotation. DC powered motors are designed to run clockwise. Run the motor for at least 30 minutes to break it in for counterclockwise running.

On our site, all of our props are identified using the North American definition. However, the packaging may show a rotation as identified in Europe. Keep this in mind to eliminate being confused.
