Lifting The Boat With A Hoist - Mercury Ocean Runner 290 Owner's Manual

OPERATION
NOTE: Always be aware of the air pressure in the air chambers.
The air pressure inside the air chambers increases 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 when the temperature decreases. Add air to the air
chambers to increase the pressure to the specified pressure.
Additionally, a correctly inflated boat may become over inflated
when in direct sunlight or as the temperature increases. This will
require the air chambers to be deflated until the specified air
pressure is reached.

Lifting the Boat with a Hoist

Remove the engine and all equipment from the boat.
Make sure that nobody is on‑board during lifting.
Attach straps to the four lifting rings attached to the hull.
Adjust the straps so the boat is level when lifted.
