Proper operation during the break-in period will help ensure maximum life and performance from your engine. The following guidelines will explain proper break-in procedures.

Failure to follow the break-in procedures described below can result in severe engine damage.
Be sure to follow the engine break-in procedures described below.

Break-in period: 10 hours

Break-in procedure

1. For the initial 2 hours:

Allow sufficient idling time (about 5 minutes) for the engine to warm up after cold engine starting.

Running at high speed without sufficient warm-up may cause severe engine damage such as piston seizure. Always allow sufficient idling time (5 minutes) for the engine to warm-up before running at high speed.

After warming up, run the engine at idling speed or the lowest in-gear speed for about 15 minutes.
During the remaining 1 hour and 45 minutes, if safe boating conditions permit, operate the engine in gear at less than 1/2 (half) throttle (3000 r/min.).

You may throttle up beyond the recommended operating range to plane your boat, then immediately reduce the throttle to the recommended operating range.

2. For the next 1 hour:
   Safe boating conditions permitting, operate the engine in gear at 4000 r/min. or at three quarter throttle. Avoid running the engine at full throttle.

3. Remaining 7 hours:
   Safe boating conditions permitting, operate the engine in gear at the desired engine speed.

You may occasionally use full throttle; however do not operate the engine continuously at full throttle for more than 5 minutes at any time.

Running continuously at full throttle for more than 5 minutes at a time during the last 7 hours of break-in operation may cause severe engine damage such as seizure.
During the last 7 hours of break-in operation, do not operate at wide open throttle for more than 5 minutes at a time.

BEFORE ATTEMPTING TO START THE ENGINE

1. Make sure the motor has been lowered into the water.

2. Turn the air-vent screw on top of the fuel tank cap fully counterclockwise to open the vent.

3. Turn the fuel cock lever to the left.

When turning the fuel cock lever to the left, fuel can flow from the built-in tank.
