WARNING

Installation of the anti-rotation bolt is mandatory!

Failure to install the anti-rotation bolt may result in the fairing rotating while the

boat is underway. The effect may be violent movement and loss of steering. This

could result in serious injury or death to passengers and/or damage to the boat or

other property.

Installation in a Cored Fiberglass Hull Dimension equal to the thickness of the hull’s outer skin to ensure adequate clearance The core (wood or foam) must be cut and sealed carefully. The core must be protected from water seepage, and the hull must be reinforced to prevent it from crushing under the hull nut allowing the sensor to become loose.
