Blackfin Skeg Protector (MEDIUM)

BlackFin Skeg Protector is easy-to-install and is engineered to take punishment and enhance the performance of your boat.
Because it's attached using a special urethane adhesive (included in the kit), no drilling or fasteners are needed.
Plus, this high-strength adhesive absorbs the force of impacts with underwater obstructions while sealing out sand and debris.
Because it is a true-shaped component on both sides, it balances flow and reduces vibration.
Tapered wings add structural reinforcement and create lift.

Item notes:
Manufacturer suggests that at least 1/2 the original skeg length should be present on the motor's lower end for installation of this product.

Use larger size if between sizes.
The Mercruiser Alpha 1 measurements would indicate that it would use the medium size but it takes the small size.

Size: (Length of lower gear case)
Medium – 12-1/2" and 14-1/2"
