3. INSTALLATION It is your responsibility to choose a
boat suitable for the engine (2 horse-
power).
manufacturer’s power recommenda-
tion. Damage and injury may result.
Two shaft lengths are available for
the BF2A, either long or short, to
match the transom height of the
boat.
1. Installation Position
Install at the stern at the center line
of the boat.
2. Installation Height
For proper propellei depth and engine
cooling, the boat’s transom height
must match the motor’s shaft
length. The short shaft motor re-
quires a transom height of about 15
in. The long shaft motor requires a
transom of height about 20 in. Once
the boat is in the water and loaded,
check proper motor depth by looking
at the anti-cavitation plate: with the
motor not running, the plate should
be about 100 mm (4 in.) below the
surface of the water.
STERN CENTER
CAVITATION
During operation, check to be sure the anti-cavitation 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 df the water, reducing
engine cooling. Loading too much or too far rearward will push the motor
deeper, reducing performance.
CAUTION: Insufficient water supply (anti-cavitation plate out of the
water) may cause overheating that will damage the outboard motor.
