CAUTION Your Universal Diesel engine is supplied with top quality, factory tested components. These will not, however, replace safe practices in the handling of fuel and the use of your engine. The following procedures, if observed, will help insure safe operation and prevent damage to your engine and its components. SAFETY PROCEDURES: KEEP THE ENGINE AND ENGINE COMPARTMENT CLEAN AND FREE FROM OILY WASTE AND CLOTHS. KEEP FUEL AND OIL OUT OF BILGE.
-CAUTIONFRESH WATER COOLING SYSTEM: ALL MODELS EXCEPT M-15. THIS SYSTEM MUST BE FILLED SLOWLY WITH A SOISO BLEND OF WATER AND A GOOD GRADE OF PREMIUM ANTIFREEZE. (THE COOLANT BLEND MAY CHANGE, BASED ON CLIMATIC CONDITION IN YOUR AREA.) OR YOU MAY ALSO USE CLEAN FRESH WATER WITH AN ANTI RUST INHIBITOR. DO NOT USE PURE ANTIFREEZE. AFTER ENGINE HAS REACHED OPERATING TEMPERATURE IT MAY REQUIRE ADDING MORE COOLANT AS THE AIR IS PURGED FROM THE SYSTEM.
GENERAL INFORMATION ENGINE: Universal Diesel engines are four stroke engines. They are designed with special swirl combustion chambers, balanced crankshaft system for minimum vibration and noise levels. COOLING SYSTEM: All Models Except M-15 Engines are fresh water cooled, employing a rubber impeller sea water pump moving sea water through a heat exchanger thereby lowering the temperature of the fresh water coolant.
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.
Transmission shifting controls must allow the clutch to engage in the full forward and reverse positions. Restricted or partial engagement will cause undue wear. The transmission should always be in the neutral position before starting the engine. Also, the transmission shifter arm must be at a 900 angle to the transmission bracket cable when in neutral. DO NOT LEAVE GEAR IN FORWARD DURING SAILING WITH ENGINE OFF.
STARTING THE ENGINE 1. Have safety equipment on board and know how to use it. 2. Ventilate engine compartment by opening hatches. 3. Be sure engine compartment is thoroughly ventilated. (Run blowers for 4 minutes before starting engine, if installed.) 4. Turn blowers off after starting or before starting to eliminate excessive battery drain, if preferred. 5. Transmission lever should be in neutral. (Center Position) 6. Place throttle lever at 1/3 open position. 7.
CAUTION COOLING SYSTEM IS UNDER PRESSURE AFTER OPERATION. REMOVE CAP SLOWLY. COOLANT WILL BE VERY HOT, USE A RAG. YOU COULD GET BURNED. ENGINE BREAK-IN AND GENERAL RUNNING 1. Engine break-in period should be approximately 10 hours of operation at 75% of normal cruising speed. 2. On your trial cruise, check the propeller shaft for abnormal vibration and engine mounts for tightness. Realignment of the propeller shaft may be required if noticeable vibration is present.
DECOMPRESSION LEVER A decompression lever fitted to the engine enables the user to start the engine easier when it is extremely cold, when the battery is low or when bleeding the fuel system. There is no decompression lever on Models 12, M2-12, M3-20, M4-30 and M-35. -CAUTIONTHE DECOMPRESSION LEVER MUST NOT BE USED TO STOP THE ENGINE EXCEPT IN EMERGENCY SITUATIONS SUCH AS RUN AWAY ENGINE OR THROTILE DAMAGE, AS SERIOUS DAMAGE CAN BE DONE TO THE EXHAUST VALVES.
Operating temperature is approximately 165°F to 195°F on all models except M-15. Operating temperature is approximately 135°F to 155°F on Model 15. The ammeter should indicate the charge required based on equipment and battery condition. There are three (3) New style "Universal" panels. 1. Standard: Includes temp. and AMP gauges, oil light, on-off key switch, glow plug and start 300680 buttons. 2. Deluxe: 300685 Same as Standard plus a tachometer with 4 selection stations on the back.

PREPARING THE ENGINE FOR WINTER STORAGE OR LAYUPS Proper preparation of your engine for storage will avoid damage and minimize expense when agai,n placing your engine in service. NOTE: It is recommended that your engine be winterized by an authorized Universal mechanic or at least, a trained mechanic familiar with the engine and its options. LUBRICATION SYSTEM: 1. Before boat is lifted out of the water, run the engine until operating temperature is attained. 2.
3. You should now have antifreeze in sea water pump, hoses, heat exchanger and exhaust system. 4. If aqua-lift or pot type muffler is used, it is recommended to drain prior to pumping antifreeze thru system and afterwards to prevent coolant from backing up into the engine. SEA WATER COOLING SYSTEM: Model M-15 OPTION #1 1. Open the cylinder block drain cock on the side of the block where hose from water pump enters, and drain. 2.
EXHAUST SYSTEM: 1. Exhaust pipes and muffler should be drained of sea water. Allow the exhaust pipes to dry out. Seal exhaust pipe end to prevent entrance of moisture into the engine through exhaust valves that are open. 2. See Option -2 under Sea Water Cooling System appropriate for your model. 3. All can type mufflers should be drained after any long periods of cranking, as Sea Water pump will fill the muffler causing water to backup and enter the engine. ELECTRICAL SYSTEM: 1.
PREPARING ENGINE FOR SPRING SERVICE Preparation of the engine should include all those items of maintenance necessary to permit satisfactory operation of the engine. A properly serviced engine will give a full season of carefree pleasure. The amount of service needed will be determined by the storage procedure of the previous fall. Refer to the section of the manual covering initial start up of the engine. LUBRICATION SYSTEM: 1.
EXHAUST SYSTEM: 1. Check all hoses and hose clamps for serviceability and security. Any worn or damaged hoses or clamps must be replaced before operation. 2. Check all valves and remove all plugs before operation. 3. Check complete system monthly for leaks, make repairs as needed. ELECTRICAL SYSTEM: 1. Inspect all wiring, terminals, controls and switches for damage or corrosion. 2. Install a fully charged battery and connect it correctly. (NEGATIVE GROUND.
MAINTENANCE OF YOUR ENGINE Unless major repair work is done on the engine, timing should not be required. FUEL INJECTION TIMING: Basic tools required: (A) - 10 MM (B) - 13 MM (C) - 17 MM (D) - 12 MM (E) - 27 MM Socket wrench Socket wrench Open end wrench Box end wrench Socket (1-1/16") Engine firing order - Two cylinder - 1 - 2 (Front V belt end) Three cylinder - 1 - 2 - 3 Four cylinder - 1-3-4-2 1.
