4. The power trim pump is internally protected from thermal
overload. If it overheats, it will shut off, allowing itself to cool
and then reset. However, it is recommended that the power
trim system be installed with additional overload protection.
Therefore, the power trim may be protected from overload by
a 110 amp fuse in the power supply to the pump and a 20 amp
in‑line fuse to the switch power.
5. A 110 amp fuse is located on the starter.
