3. INSTALLATION
It is your responsibility to choose a boat suitable for the engine.
This engine is; 5.0 HP (3.7 kW)
Do not exceed the boat manufacturer's power recommendation. Damage
and injury may result.
1. Installation position
Install at the stern, at the center line of
the boat.
STERNCENTER
2. Installation height
For proper propeller depth and engine
cooling, the boat's transom height
must match the motor's shaft length.
The short shaft motor requires a
transom height of about:
381 mm (15.0 in)
The long shaft motor requires a
transom height of about:
508 mm (20.0 in)
Once the boat is in the water and
loaded, check proper motor depth by
looking at the anti-ventilation plate:
with the motor not running, the plate
should be below the surface of the
water.
It should be about:
100 mm (3.9 in)
ANTI-VENTILATION PLATE
During operation, check to be sure the anti-ventilation plate remains under
water at all times and that water flows from the water check hole.
Excessive or imbalanced loading will affect the motor's water depth.
Loading too far forward will raise the motor out of the water, reducing
engine cooling. Loading too much or too far rearward will push the motor
deeper, reducing performance.
Insufficient water supply (anti-ventilation plate out of the water) may
cause overheating that will damage the outboard motor.
