Fitment & Ordering

Verify the exact engine model, shaft length, mounting bolt pattern, bracket dimensions, engine weight and horsepower, transom capacity and steering and tilt clearances with the boat, engine and bracket manufacturers. Confirm that the resulting engine height meets the engine manufacturer's operating requirements rather than assuming a 5-inch increase is correct for every XL-shaft installation. Confirm package contents, bracket quantity and required mounting hardware before purchase. Follow the manufacturer's installation instructions and have a qualified marine installer assess the setup. Contact C and O Marine Parts with your boat, engine and existing mounting measurements for help confirming the correct configuration.
