6. Test Run
1. Start engine and check if shifting is smooth.
2. After completing warm-up operation, check idle engine
speed.
Complete test run during break-in operation.
Trolling Engine Speed :
1,150 - 1,250 r/min
4. Run at 3,000 r/min or half of WOT for initial 2 hours, then at
4,000 r/min or 3/4 of WOT for 1 hour.
5. Check that shifting into reverse will not tilt up outboard motor
and allow water to run into boat.
3. Shift gear into forward (F) and run at idle speed
(for approximately 10 minutes).

5. Break-in Operation
Break-in operation is needed to smooth sliding surfaces
between components such as pistons and cylinder, piston
rings, piston pins, crank shaft, connecting rods, and intake
and exhaust valves.
