3.1 General
Your boat is designed to be powered with one or
two 2-cycle or 4-cycle outboard motors. 4-cycle
outboard engines do not use an oil injection sys-
tem and are not equipped with an oil tank. 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 mo-
tors 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 infor-
mation 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.
WARNING
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.
WARNING
DO NOT INHALE EXHAUST FUMES! EXHAUST CONTAINS
CARBON MONOXIDE THAT IS COLORLESS AND ODORLESS.
CARBON MONOXIDE IS A DANGEROUS GAS THAT IS
POTENTIALLY LETHAL.
3.2 Drive System Corrosion
Each outboard motor is a complete drive sys-
tem 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 recom-
mended 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
Chapter 3:
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, pollu-
tion, current, etc. can have an effect on marine
growth.
Galvanic corrosion is the corrosion process oc-
curring 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
sacrificial anodes to prevent galvanic corrosion
problems. The anodes must be monitored and
replaced as necessary. For locations and mainte-
nance, please refer to the engine owner’s manual.
When leaving the boat in the water, tilt the mo-
tors 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.
