Wash the exterior and interior of the jet drive with fresh water after each use.
Each month, spray Quicksilver or Mercury Precision Corrosion Guard on
external metal surfaces. Do not spray Corrosion Guard on the corrosion control
anodes. Coating the anodes with Corrosion Guard will reduce the effectiveness
of the anodes.
Engine Break‑In Procedure
NOTE: Do not use premixed gas and oil in this engine. Use straight gasoline
during engine break‑in and after engine break‑in.
The engine break‑in procedure for your OptiMax engine is important to ensure
proper performance and maximum life from the engine. The following break‑in
procedure allows the internal engine parts to wear evenly. Incorrect engine
break‑in can shorten the engine life.
The engine automatically receives extra oil during the first hours of operation.
For most boaters, this extra oil mode will be complete in about ten hours.
First hour
• Allow the engine to warm up for 30–60 seconds.
• Avoid continuous operation at idle speed for more than 10 minutes.
• Run the engine the majority of time between 3000–4500 RPM,
approximately three quarter throttle.
• Vary the engine speed; change the engine speed approximately every
two minutes.
• Short bursts of full throttle for periods up to 10 seconds are acceptable.
Next three hours
• Change the engine speed every 10 minutes.
Starting the Engine
Before starting, read the Prestarting Check List, Special Operating
Instructions, and Engine Break‑In Procedure.
