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 manu-
facturer. The oil must be checked before each use and changed
regularly as per engine manufacturer’s schedule.
Each manufacturer of the various outboard motors provides
an owner’s information manual with its product. It is impor-
tant 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
CONTAINS CARBON MONOXIDE THAT 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. Rou-
tine 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 cor-
rosion.
Marine growth occurs when components are left in the water
for extended periods and can cause poor performance or per-
manent damage to the exposed components. The type of
growth and how quickly it occurs is relative to the water con-
ditions 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
properly protected. Outboard motors are equipped with sac-
rificial 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 motor 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.
