What is the proper break-in procedure for an OptiMax outboard?
Break-in is important to insure correct engine performance and life. Follow the procedure listed in the Operation, Maintenance and Warranty Manual. Generally, for the first two hours we recommend avoiding extended periods of idle or wide-open throttle, or holding the engine at one speed for extended periods of time. New two-stroke engines require additional oil during break-in; OptiMax engines use programming inside the computer to increase the oil mixture during the specified break-in period.
Break-in procedures are described in the Operation, Maintenance and Warranty Manual supplied with each engine. Use the Bookshelf link on the Mercury Dockstore page if you need to place an order for a replacement manual.
What is the advantage of the OptiMax/DFI Synthetic Blend 2-Cycle Outboard Oil?
The OptiMax/DFI Synthetic Blend 2-Cycle Outboard oil is specifically designed for Mercury Marine direct injected outboard engines. The additive package used in this oil is superior to the other oils we produce and formulated to provide an extra margin of protection in the OptiMax engines. OptiMax engines have additional pressures and temperatures over their carbureted and EFI counterparts.
Can I mix the OptiMax oil with the Premium Plus oil that I have been running in my OptiMax?
Yes. OptiMax oil can be mixed with the Mercury Premium Plus oil that you have been running in your OptiMax.
*OptiMax Oil is ONLY for use with OptiMax Outboard engines and is NOT approved for use with EFI or Carbureted engines manufactured by Mercury Marine, nor is it recommended for use with engines from another manufacturer.
Do I have to use a SmartCraft Monitor with my OptiMax engine?
No, however the operator will be at a disadvantage without a display, the only warning information available will be the horn, and the operator may not be able to identify what caused the warning system to activate. An overview of the warning system follows:
The SmartCraft warning system incorporates the display screen, the warning horn and the Guardian Protection system. The warning horn is located inside the remote control or is part of the ignition key switch wiring harness.
Alarms Warnings - When a problem is detected, the warning horn sounds and the name of the offending alarm appears on the display.
- If problem can cause immediate engine damage - the horn will sound continuously and the Engine Guardian System will respond to the problem by limiting engine power. Immediately reduce throttle speed to idle and refer to the warning messages on the monitor and descriptions in the Operation, Maintenance and Warranty Manual to tell you what to do about it.
- If problem will not cause immediate engine damage - The horn will sound but not continuously.
Refer to the warning messages on the monitor and descriptions in the Operation, Maintenance and Warranty Manual to tell you what to do about it. Use the Bookshelf link on the Dockstore page if you need to place an order for a replacement manual.
Engine Guardian System - Monitors the critical sensors on the engine for any early indications of problems. The system will respond to a problem by reducing engine power in order to maintain a safe operating condition. The monitor display screen will show the percent of power available.
How do I connect the older style gauges to the new OptiMax engines?
Your dealer has detailed service information available for connecting to the older style gauges. Due to the technical nature of the conversion, we highly recommend having a technician trained on OptiMax products perform the work.
