A standard taper is provided at no additional charge. If you would like a double taper, please select this item in addition to the prop shaft. Please provide the year and make of your boat, drive type (direct, vee) and the color of the coupler (if this is a replacement--disregard if it's a new build). Enter this information in the box provided above. We will provide a new coupler to ensure an accurate fit as well as a prop nut kit and key.
Note: Measure your prop shaft from the face of the coupling (the side that bolts to the transmission) to the end.
