GENERAL CARE:
If the boat is left afloat for periods of a month or more, the engine should be started at least every
14 days to prevent internal corrosion.
Regularly spray external unpainted surfaces and exposed, unpainted electrical equipment with a
corrosion and moisture protective coating.
ENGINE ALIGNMENT TO SHAFT COUPLING:
It is the responsibility of the dealer or yard to properly align the engine and shaft to within .002" to
.004" inches. The boat must be in the water when this is done. Alignment is not the responsibility
of Universal Motors. If not done properly damage to shaft and engine can occur, usually vibration
is present
if alignment is off.

PREPARATIONS FOR STARTING YOUR NEW DIESEL ENGINE
For long dependable service, become familiar with the operating requirements of your engine.
All Universal Diesel engines are completely factory tested under load conditions before shipment.
In preparation for starting engine, oil must be added to the crankcase. Refer to specifications for
lubrication, oil type and capacity. Recheck oil level
on dipstick, it should be to full mark, do not overfill,
when checking oil remove dipstick, wait 15 seconds, then recheck.
The oil level should
be checked before the first start-up each day. Dipstick has high and low markings.
Oil levels either above or below these marks should never be allowed. Oil is put into the engine by
removing the screw cap
on the top of the rocker arm cover. Fill the crankcase with oil to the upper
mark on the dipstick and securely replace the filler cap.
THE
TRANSMISSION IS SHIPPED WITH OIL, BUT SHOULD BE CHECKED PRIOR TO OPERATION.
Refer to specification of oil type and capacity. Recheck oil level on dipstick. (DIPSTICK TO BE IN-
SERTED ONLY.
DO NOT SCREW IN). See transmission instructions for additional information. FILL
TO INDENTED RING
ON DIPSTICK only.
An unrestricted water supply must be provided to the engine. Use a minimum of 1/2" through hull fit-
ting. Locate the scoop where it will have a
full supply of water at all times regardless of running posi-
tion or rough seas. A sea cock or gate valve is necessary at the water inlet point. The water pump has
a
3/8" N.P.T. suction inlet and the heat exchanger has a 3/8" N.P.T. water outlet. Use a non-
collapsible hose for the suction side. A water strainer installed in the line ahead of the water pump aids
in preventing clogging of the cooling system. The exhaust pipe is 1-1/4" N.P.T.' on all models except
M-50, which is 1-112" N.P.T.
The fresh water manifold
on all models except M-15 should be filled slowly to the bottom of the filler
cap. A
50/50 mixture of fresh water and antifreeze solution is acceptable as an all weather coolant,
eliminating the need to drain the fresh water system for cold weather operation or storage. A coolant
mixture may change based on climatic conditions in your area. The rust preventive will aid in reducing
rust formation
if no antifreeze is used.
Model 15, being sea water cooled, draws its water directly from the sea, filling the engine system and
discharging the hot water overboard into the exhaust line.
Be sure water pump is lubricated by turning grease cup (if provided on your engine) clockwise 112 turn
at
30 hour intervals. Pumps with no grease cup do not require lubrications.
