FAQs

The four mounting holes should be marked and drilled 2.68 inches (68 mm) apart.

The included tiller pin is designed for use with a quadrant or tiller arm up to 0.79 in. (20 mm) thick. If you lack a suitable quadrant, you must install a compatible tiller arm.

Professional installation is highly recommended because installation requires specific knowledge about rudder operation to avoid damage.

Annually examine all bolted connections and the locknut that secures the drag link. Tighten if necessary.

You should always wear safety goggles, ear protection, and a dust mask when drilling, cutting, or sanding.

You must not cut the cables connected to the drive unit, as cutting the cables will void the warranty.

No, the drive unit is not water-resistant and must be installed where it will not be exposed to water. Exposure to immersion, dripping water, or hose spray will damage it.

The drive unit movement must be limited by physical end stops, not by the drive unit itself. Failing to install end stops can result in damage to the unit.

The drive unit should be mounted with the motor pointing sideways if possible, as mounting with the motor up or down may create more friction and cause more wear over time.
