Power Trim and MerCathode Overload Protection

If an electrical overload on the electrical system occurs, a fuse will burn out (blow). Find and correct the cause before replacing
the fuse.
NOTE: If you must operate the engine in an emergency, turn off and disconnect all accessories from the engine and
instrumentation wiring if you cannot find and correct the cause for the electrical overload or excessive current draw. Replace
the fuse. If the fuse burns out, the electrical overload has not been eliminated. Further checks must be made on the electrical
system. Contact your Mercury Diesel authorized repair facility.
1. The power trim system is protected from overload by a 110‑amp fuse and a 20‑amp in‑line fuse on the power trim pump.

3. The Quicksilver MerCathode System, if equipped, has a 20‑amp in‑line fuse in the wire that connects to the positive (+)
terminal on the controller. If the fuse is burned out (blown), the system will not operate, resulting in a loss of corrosion
protection.
