OPERATION
Operating in Saltwater or Polluted Water
If the boat is kept moored in the water, always tilt the outboard so
the water intake is completely out of water (except in freezing
temperatures) when not in use.
Wash down the outboard exterior and flush out the exhaust outlet
of the jet drive with fresh water after each use. Each month, spray
Mercury Precision or Quicksilver Corrosion Guard on external
metal surfaces.
NOTE: Do not spray on corrosion control anodes as this will reduce
the effectiveness of the anodes.
Operating In Shallow Water
The life of the impeller and water intake can be greatly increased
by avoiding the intake of sand and gravel. The intake suction will
act like a dredge when the water intake comes close to the bottom.
It is better to stop the engine and drift up to shore when landing,
and to shove off with an oar when leaving. The engine can idle
through areas of water less than 61 cm (2 ft.) deep, but there
should be more than 61 cm (2 ft.) of water under the boat when
increasing speed to reach full plane.
Once the boat is on plane, the boat speed will prevent the ingestion
of gravel and other debris from the bottom. The suction is still
present, but the water intake passes too quickly over the bottom
to allow debris to be drawn into the water intake.
When boating through shallow water areas, choose a course of
travel that avoids sharp rocks and other underwater obstacles that
could damage the boat. Running the boat through these areas on
full plane may be helpful as the boat will be riding higher in the
water. If the boat gets stuck on the bottom, immediately stop the
engine and move the boat to deeper water.
How the Jet Drive Operates
A jet driven boat has substantially different handling characteristics
compared to a propeller driven boat. It is recommended that the
operator adjusts to these characteristics by experimenting in open
water at both high and low speeds.
