PROPULSION SYSTEM
1.1 General
Your Scout is designed to be powered with a 2-cycle or 4-cycle
outboard motor. 4-cycle outboard engines do not use an oil
injection system and are not equipped with remote oil tanks.
They have an oil sump in the crankcase that must be kept full of
the type of oil recommended by the engine manufacturer. The
oil must be checked before each use and changed regularly.
Each manufacturer of the various outboard motors provides an
owner’s information manual with its product. It is important
that you read the manual(s) very carefully and become familiar
with the proper care and operation of the engines and drive
systems. A warranty registration card has been furnished with
each new engine and can be located in the engine owner’s
manual. All information requested on this card should be filled
out completely by the dealer and purchaser and then returned
to the respective engine manufacturer as soon as possible.
DO NOT ATTEMPT TO SERVICE ANY ENGINE OR
DRIVE COMPONENT WITHOUT BEING TOTALLY
FAMILIAR WITH THE SAFE AND PROPER SERVICE
PROCEDURES. CERTAIN MOVING PARTS ARE
EXPOSED AND CAN BE DANGEROUS TO SOMEONE
UNFAMILIAR WITH THE OPERATION AND FUNCTION
OF THE EQUIPMENT.
DO NOT INHALE EXHAUST FUMES! EXHAUST
C O N TA I N S C A R B O N M O N OX I D E T H AT
IS COLORLESS AND ODORLESS. CARBON
MONOXIDE IS A DANGEROUS GAS THAT IS
POTENTIALLY LETHAL.
1.2 Drive System Corrosion
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 effect on marine growth.
Galvanic corrosion is the corrosion process occurring when
different metals are submerged in an electrolyte. Seawater is
an electrolyte and submerged engine components must be prop-
erly 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.
