Scout Boats 320 LXF, Owner'S Manual

Page: 13 / 171

Each outboard motor is a complete drive system with the gear
case being just forward of the propeller and connected to the
power head with a vertical drive shaft. All engines require some
maintenance. Routine maintenance recommended for your
engine is outlined in the engine owner’s manual. Routine
maintenance is normally the primary concern unless the boat is
to be kept in saltwater for extended periods of time. Then the
main concerns are marine growth and galvanic corrosion.
Marine growth occurs when components are left in the water for
extended
periods and
can cause poor
performance or
permanent
damage to the
exposed
components.
The type of
growth and
how quickly it
occurs is relative to the water conditions in your boating area.
Water temperature, pollution, current, etc. can have an e
ff ect on
marine growth.
Galvanic corrosion is the corrosion process occurring when
di
ff erent metals are submerged in an electrolyte. Seawater is an
electrolyte and submerged engine components must be properly
protected. Outboard motors are equipped with sacrificial anodes
to prevent galvanic corrosion problems. The anodes must be
monitored and replaced as necessary. For locations and
maintenance, please refer to the engine owner’s manual.
When leaving the boat in the water, tilt the motors as high as
possible. This will decrease the risk of marine growth around
the cooling inlets, propeller and exhaust ports and damage from
galvanic corrosion.
DO NOT PAINT THE OUTBOARD MOTOR WITH ANTIFOULING PAINTS
DESIGNED FOR BOAT HULLS. MANY OF THESE PAINTS CAN CAUSE
SEVERE DAMAGE TO THE ENGINE. CONTACT YOUR SCOUT DEALER OR
ENGINE MANUFACTURER FOR INFORMATION ON THE PROPER
PAINTING PROCEDURES.
