3. Use one of two methods to determine
when the proper amount of oil has been
delivered to the engine.
a. Pre-measured Method – this method
requires the operator to set aside a known
quantity of oil prior to filling. For example,
if the engine requires 22 quarts of oil, the
operator may want to pump from a 5
gallon container, adding two additional
quarts as the container empties.
b. Timed Method – the timed method is
used when pumping from a container of
unknown capacity, or a reservoir. The flow
of oil through the system varies primarily
with the viscosity and temperature of the
oil. Under normal conditions 75°F to 85°F
(24°C to 29°C), the system pumps four
quarts of 40 weight oil (one gallon) in
approximately 90 seconds.
NOTE
Models 946DB or 946DBT pump
eight quarts (two gallons) of 40
weight oil in approximately 90
seconds. Filling time is a function of
several factors, including the oil
temperature and weight. Oil (40
weight) at 85°F (29°C) pumps
approximately 20% faster than the
same oil at 75°F (24°C).
Fresh oil
should be 75°F (24°C) or warmer
before pumping!
FILLING THE ENGINES
1. Loosen the oil filler cap on the engine or
remove the dip stick to allow air to enter
the crankcase.
2. Insert the PVC wand of the drain/fill hose
into a container of fresh oil.
3. Release the fail-safe lock device on the
pump/motor unit valve handle and direct
the arrow-shaped tip to PORT ENGINE.
4. Flip the pump motor control switch on
the system to the FILL position. The
pump will start immediately and you will
observe the oil moving through the clear
tubing toward the pump/motor unit. You
should hear a noticeable change in the
sound (speed) of the pump motor when
the oil enters the pump.
5. Continue to operate the pump until a
measured amount of oil has been
pumped into the engine’s crankcase.
Fresh oil is pumped at the rate of about
one gallon each 90 seconds.
NOTE
Models 946DB or 946DBT pumps
fresh oil at a rate of two gallons per
90 seconds.
6. Flip the pump motor control switch to the
OFF position when the oil pan nears its
filled capacity and check the proper oil
level with the engine’s dip stick (or other
measuring device supplied with the
engine). If filling is completed, place the
fail-safe switch in the OFF position.
NOTE
If you have overfilled an engine, you
may simply flip the motor control
switch to the DRAIN position for a
few seconds and remove the excess.
Davit Lift System
The “Davit Lift” system should NOT be
bonded to the ship’s bonding system. Zinc
anodes must be placed on BOTH main
tubes of the lift. Any portion of the system
that extends below the waterline and comes
in contact with the water should be painted
with an appropriate bottom paint.
Helm Seat
The helm seat can be adjusted fore and aft.
The front of the seat can be positioned as a
“leaning post.”
