Chapter 1:
PROPULSION SYSTEM
1.1 General
Your Wellcraft is designed to be powered with 2-cycle or
4-cycle outboard motors. Each manufacturer of the
various outboard motors provides an owner’s
information manual with its product. It is important that
you read the manual very carefully and become familiar
with the proper care and operation of the engine and
drive system. 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.
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 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.
1.3 Engine Lubrication
2-cycle outboard motors are lubricated by a variable
ratio oil injection system. The oil tanks are mounted in
the stern bilge and accessed through a hatch in the
cockpit sole. They are filled through fill fittings in the top
of each tank. Each oil fill is opened by turning it counter
clockwise. After filling tank, tighten the fill by turning it
clockwise until it is snug.
Note: Do not over tighten the oil fill cap. If the
cap is over tightened, it could be damaged
allowing oil to leak out of the tank or
water to contaminate the oil system.
