OPERATION
52
If you keep your boat moored in the water, always tilt the outboard
so the gearcase is completely out of water (except in freezing
temperatures) when not in use.
Wash the outboard exterior and flush out the exhaust outlet of the
propeller and gearcase with fresh water after each use. Each
month, spray Mercury Precision or Quicksilver Corrosion Guard on
external metal surfaces. Do not spray on corrosion control anodes
as this will reduce the effectiveness of the anodes.
Pre‑Starting Instructions
1. Check the engine oil level.
2. Make sure the cooling water intake is submerged.
NOTICE
Failure to provide sufficient cooling water will damage the water
pump and cause the engine to overheat. Provide a sufficient
supply of water at the water inlets during operation.
Engine Break‑in Procedure
IMPORTANT: Failure to follow the engine break‑in procedures can
result in poor performance throughout the life of the engine and
can cause engine damage. Always follow break‑in procedures.
