FAILURE TO FOLLOW THE INSTRUCTIONS AND SAFETY PRECAUTIONS IN THIS MANUAL CAN RESULT IN SERIOUS INJURY OR DEATH. KEEP THIS MANUAL IN A SAFE LOCATION FOR FUTURE REFERENCE. Copyright © 2009 Tohatsu Corporation. [. . . ] If the engine is not warmed up beforehand, the engine life will shorten greatly. This outboard engine automatically controls warm-up operation, namely, it runs at a speed slightly higher than idling just after it is started, and it reverts to the normal running at a preset speed after warm-up is complete. During the warm-up operation, confirm that cooling water is discharged from the check port and idle port. ! 1 2 3 4 5 6 7 8 9 10 Be sure to stop engine immediately if cooling water check port is not discharging water, and check if cooling water intake is blocked. Operating engine could lead to overheating potentially leading to engine damage. Consult an authorized dealer if the cause cannot be found. Engine speed Proper idle speed after warm-up operation. Clutch in (In gear) 700rpm Clutch off (Out of gear) 700rpm ! ! Do not shift to "F" or "R" until turning into proper idle speed. If cooling water is not discharged and engine operation is continued, the engine will overheat and damage occur. Do not exceed the full-throttle engine speed.

Before shifting into forward or reverse, make sure that boat is properly moored and outboard motor can be steered fully to the right and left. Make sure that no swimmer(s) is ahead or astern of the boat. EFO, EFTO type Turn the throttle grip toward "SLOW" and move the Shift Lever quickly to Forward or Reverse when the engine speed has reached the lowest rpm. Lock Reverse lock lever ! Attach other end of emergency stop switch tether to the operator's clothing or arm and keep it attached during cruising. Do not attach the tether to a part of clothing that can be torn easily when pulled. Arrange the tether so that will not be caught by any object when pulled. Be careful not to pull the tether accidentally during cruising. Unintentional stop of engine can cause loss of control of outboard motor. Rapid loss of engine power can lead to falling down or causing passenger(s) to be thrown over board. R N F ! ! Be sure to connect the emergency tethered stop hook to your waist or clothing. The engine will shut down when the switch lock becomes disconnected from the engine. Severe damage, and personal injury, may occur if shifting at high engine speed. Engine must be in the slow idle position before shifting is attempted. ENGINE OPERATION 47 ! Before shifting, make sure that no swimmer(s) or obstacle(s) is ahead or astern of the boat. ! Before moving the Shift Lever to Reverse, make sure the Reverse Lock is engaged (in up position). --EFO model only. Lock Reverse lock lever EPTO type While pressing the lock button on the Remote Control lever upward, swiftly move the Lever to Forward (F) or Reverse (R) to the engaging point (approx. 32° forward or backward from Neutral). If the lever is moved further forward or backward, the throttle will open.

Shallow water running 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Be sure to warm up engine well before starting cruise. Operating cold engine can give damage to it. ! Note Idle speed may be higher during warming up of engine. If shifted to Forward or reverse during warming up, it may be difficult to shift back to neutral. In such case, stop engine, shift to neutral, and restart engine to warm up. During shallow water operation, be careful not to place your hand between the swivel bracket and the stern bracket. Be sure to tilt the outboard down slowly. Note Slow down to trolling speed, and shift into neutral before setting outboard motor to shallow water drive position. Note Frequent shifting to forward or reverse can accelerate wear or degradation of parts. [. . . ] Checking after striking underwater object Striking sea bottom or underwater object may severely damage the outboard motor. Immediately bring the outboard motor to your dealer and ask for the following checks. Looseness or damage of power unit installation bolts, gear case and extension case bolts, propeller or propeller shaft, upper and lower mount rubber bolts and nuts, power trim and tilt bolts, and mount rubber cap bolts. Ask to tighten loose bolts and nuts, and to replace damaged parts. [. . . ]
