Break-in Operation
Break-in operation is needed for the purpose of smoothening sliding surfaces between components such as pistons and cylinder, piston rings, piston pins, crank shaft, connecting rods, and intake and exhaust valves.
Break-in Operation…10 hours
Test Run
Start engine and check if gear shift can be moved smoothly.
After completing warm-up operation, check idling revolution speed.
Idling Revolution Speed : 950 r/min
Tachometer : Use commercially available item.
(1) High tension cord
- Shift gear into forward (F) and run dead slow for approximately 10 minutes.
Dead Slow Revolution Speed : 900 r/min
Run at 2,000 r/min or half of WOT for initial 2 hours, then at 3,000 r/min or 3/4 of WOT for 1 hour.
Check that shifting into reverse (R) will not tilt up outboard motor and allow water to run into boat.
Complete test run during break-in operation.
