IMPORTANT: Please follow the instructions below:
Hydrogen gas is generated when charging a battery. Keep the
battery in a well‑ventilated area during charging. Remove the
battery from the boat; this will protect your hull and interior
from damage. Electric sparks, cigarette smoking, and other
sources of fire must be avoided in the charging area to prevent
explosion of the battery.
The battery fluid (electrolyte) contains sulfuric acid. If
electrolyte is spilled on the skin or clothes, wash with plenty
of water and consult a medical doctor. Always use safety
glasses and rubber gloves when handling the battery.
Propeller Selection
For best all around performance from your outboard/boat
combination, select a propeller that allows the engine to operate
in the upper half of the recommended full throttle RPM range with
the boat normally loaded. This RPM range allows for better
acceleration while maintaining maximum boat speed.
The propeller supplied with your outboard provides the best overall
performance under average operating conditions.
