OPERATION
28
NOTE: Always be aware of the air pressure in the air chambers.
The air volume inside the air chambers will expand as the internal
air temperature rises; this will cause the air pressure to fluctuate
depending on water temperature and weather conditions. A boat
that is correctly inflated, may experience a drop in air pressure
and require additional air when temperatures decrease; or it may
become over inflated when in direct sunlight or as the
temperatures increase. This will require the air chamber to be
deflated until the recommended air pressure is reached.
2. Unscrew the valve cap from the keel air chamber valve by
turning a quarter of a turn counterclockwise. Push in on the
valve stem and rotate to the closed position. Attach the air
hose adapter to the air valve. Inflate the keel to the
recommended air pressure of 0.25 bar (3.6 psi).
3. After inflation, install the valve caps tight (turn clockwise).
Outboard Power
Choose an outboard for the boat that is in accordance with the
horsepower range and maximum weight limit. Refer to the
Specification table in this manual or the manufacturer's plate on
the boat for the maximum outboard horsepower and outboard
weight.
Install the outboard along the centerline of the boat transom.
Fasten the outboard to the transom following the recommended
installation instructions provided with the outboard or from the
outboard manufacturer.
Check outboard for tightness on transom before each use.
!
WARNING
Using an outboard that exceeds the maximum horsepower limit
of a boat can: 1) cause loss of boat control 2) place too much
weight at the transom altering the designed flotation
characteristics of the boat or 3) cause the boat to break apart
particularly around the transom area. Overpowering a boat can
result in serious injury, death or boat damage.
Pre‑Operating Check List
• Check the inflation pressure of the air chambers.
