(3) Fuel Tank (optional) Be sure to attach a drain cock to the fuel tank to enable dirt and water to settle at the bottom of the tank to be drained off. The fuel outlet should be positioned 2030mm above the bottom of the tank so that only c lean fuel is used.
3. Operation 3.1.2 Lube Oil Air temperature Single grade Multi grade 'C 1' Using other than the specified lube oil will lead to seizure of parts, abnormal wear, and shorten engine life. (1) Selection of Engine Lube Oil Use the following lube oil: • API Classification ............................. CD • SAE Viscosity ....... ...................... 15W40 (2) Selection of Oil for Marine Gear • SAE Viscosity ..................... ...............
3. Operation I Handling of Cooling Water 1. Choose antirust which will not have any adverse effects on the materials (cast iron, aluminum, copper, etc.) of the engine's fresh water cooling system. 2. Use the proper mixing ratio of antirust to fresh water strictly as instructed by the antirust maker. 3. Replace the cooling water periodically, according to the maintenance schedule given in this operation manual. 4.
3. Operation 3.2.4 Supply Cooling Water (For Fresh Water Cooling Type Only) Supply cooling water according to the following procedures. Be sure to add antirust or ant ifreeze to the cooling water. I 1. Be sure to close the 3 water d rain cocks (See illustration right). Note: The water drain cocks are opened before shipping from the plant.
3. Operation 3. Pour cooling water slowly into the fresh water tank so that air bubbles do not develop. Supply until the water overflows from the filler port.
3. Operation 3.2.6 Check and Resupply Lube Oil and Cooling Water
3. Operation 3.3.1 Inspection Before Starting Before starting the engine, make it a daily rule to conduct the following inspections: (1) Visual Checks Check for the following: 1. Lube oil leakage from the engine 2. Fuel oil leakage from the fuel system 3. Water leakage from the cooling water system 4. Damage to parts 5. Loosening or loss of bolts If any problem Is found, do not o perate the engine before completing repairs.
3. Operation 3.3.2 How to Start the Engine If the cooling fresh water runs out too often, or only the cooling fresh water in the fresh water tank drops without any change in the water level of the subtank, there may be some leakage of water or air. In such cases, consult your Yanmar dealer or distributor without delay. (1) Start the engine according to the following procedures: Electric Operation 1. Open the Kingston cock. 2. Open the fuel tank cock. 3. Set the remote control lever in NEUTRAL.
3. Operation Manual Operation (Seawater Cooling Only) 1. Open the Kingston cock. 2. Open the fuel tank cock. 3. Set the remote control lever in NEUTRAL 4. Pull out the decompression lever. 5. Put the starter handle on the starter shaft, align the groove and pin, and turn by hand. When you begin turning, you will hear the sound of fuel being injected. 6. Turn the handle vigorously. When the rotation is rapid, return the decompression lever to original position. The engine starts. 7.
3. Operation Fuel System Air Venting Procedures 1. Check the fuel level in the fuel tank. Replenish if insufficient. 2. Loosen the air vent bolt at the top of the oil/ water separator by turning it 2 or 3 times. When fuel which does not contain air bubbles comes out of the bolt hole, tighten the air vent bolt. 3. Loosen the air vent bolts of the fuel filter and the fuel injection pump by turning them 2 or 3 times. 4.
3. Operation Use the clutch handle to change from FORWARD to NEUTRAL (boat stopped) to REVERSE. Shifting the clutch while operating at high speed or not pushing the handle fully into position {half clutch) will resutt in damage to clutch parts and abnormal wear. r:r:l liil 1. Before using the clutch, be sure to move the governor handle to a low speed position (1 000 rpm or less). Move the governor handle to a high speed position after completing clutch operation. 2.
3. Operation [ Engine stopping by engine stop cable Electric Operation Never turn off the battery switch or spark the battery cable during operation. Damage to parts in the electric system will result. 3.3.5 Stopping the Engine Stop the engine in accordance with the following procedures: 1. Put the remote control handle ln NEUTRAL. 2. Be sure to race the engine before stopping it. (See 3.3.4 (7)) 3. Cool down the engine at low speed (approximately 1000 rpm) for about 5 minutes. Engine stop cable 4.
3. Operation Note: The engine may be stopped by pulling out the decompression lever, but avoid doing so except in times of emergency. In this case, the engine is stopped by cutting off the air pressure. However, fuel injection does not stop, and fuel ls leftover in the combustion chamber. This will lead to abnormal combustion when the engine is restarted and is not desirable. 3.
3. Operation (3) Carry out the next periodic inspection before placing the engine in storage. Clean the outside of the engine wiping off any dust or oil. (4) To prevent condensation inside the fuel tank, either drain off the fuel or fill the tank. (5) Grease the exposed area and joints of the remote control cable and the bearings of the remote control handle. (6) Cover the intake silencer, exhaust pipe, etc. with vinyl sheets and seal them to prevent moisture from entering. 1 .
4. Maintenance & Inspection 4.1 General Inspection Rules Conduct Periodic Inspection for Your Safety. The functions of engine components will degenerate and engine performance will drop according to the use of the engine. If countermeasures are not taken, you may encounter unexpected troubles while cruising at sea. Consumption of fuel or lube oil may become excessive and exhaust gas and engine noise may increase. These all shorten the life of the engine.
4. Maintenance & Inspection 4.2 List of Periodic Inspection Items Daily and periodic Inspections are important to keep the engine in its best condition. The following is a summary of inspection and servrc1ng items by inspection interval. Periodic inspection intervals should vary depending on the uses, loads, fuels and lube oils used and handling conditions, and are hard to establish definitively. The following should be treated as a general standard only. Section 4.

4. Maintenance & Inspection 4.3 Periodic Inspection Items 4.3.1 Inspection on Initial 50 Hrs. of Operation (or after 1 Month) (1) Replacing the Engine Lube Oil and Lube Filter (1st time) During initial operation of the engine, the oil is quickly contaminated due to the initial wear of internal parts. The lube oil must therefore be replaced early. Replace the lube oil filter at the same time. It is easiest and most effective to drain the engine lube oil after operation while the engine is still warm. 1.
4. Maintenance & Inspection {3) Adjusting the Remote Control Cable The various control levers on the engine side are connected to the remote control lever by the remote control cable. The cable will become stretched and the attachments loose after long hours of use causing deviation. It is dangerous to control operation under these conditions, and the remote control cable must be checked and adjusted periodically.
4. Maintenance & Inspection 4.3.3 Inspection Every 150 hours. Replace the engine oil and the clutch lube Oil. After the second oil change, the engine oil should be replaced after every 150 hours. 4.3.4 Inspection Every 300 Hrs. (1) Replacing the Fuel Filter When there is dirt in the fuel, the filter becomes clogged, and the fuel will not flow easily. Check and replace the inside element. 1. Close the fuel cock. 2.
I 4. Maintenance & Inspection (4) Inspecting and Replacing Anticorrosion Zinc The timing for replacing anticorrosion zinc varies depending on the characteristics of the seawater and operational conditions. Inspect the zinc periodically and remove any corroded areas. Replace the anticorrosion zinc when it has been reduced to less than 1/2 of its original size.
4. Maintenance & Inspection reassembled, be very careful not to make a mistake and turn it in the wrong direction. Additionally, if the engine is being turned manually, be careful to turn it in the correct direction. Incorrect turning will twist the impeller and damage it. (3) Inspection and Adjustment of Intake/ Exhaust Valve Clearance. When operating for long periods of time, the clearance between the intake/exhaust valve and the rocker arm will change and affect operation performance.
