Section 2 - Getting to Know Your Power Package
NOTE: The main power and fuel pump relays are located next to the fuses and control
voltage to the engine with the ignition key in the on position.
4. The power trim system is protected from overload by a 110 amp fuse and a 20 amp
spade fuse on the power trim pump. The trim pump may also have an in‑line circuit
protection device in the power trim positive lead near the battery switch or battery
connection.
5. The electronic control unit of each engine has a separate power harness to minimize
voltage drop. The power harness connects to the engine starting battery and is
protected by a 10 amp spade fuse in a fuse holder located near the battery.
