Be careful when working on fuel system. Gasoline is extremely flammable and
highly explosive under certain conditions. Do not smoke or allow spark or open
flame in area. Wipe up any spilled fuel immediately.
1. Disconnect bullet connectors of trim sender wires (coming from transom assembly) from
engine harness.
NOTE: After wires are disconnected, be sure to loosen them from clamps or Sta-Straps
retaining them to engine or hoses.
2. Disconnect MerCathode wires from MerCathode controller if mounted on engine (some
models).

Center lifting eye (located on top of thermostat housing) is used for engine align-
ment only. DO NOT use to lift entire engine.

occur. DO NOT allow lifting sling to hook or compress engine components or

from boat stringers.
