4. Start the engine. After starting, travel with caution, at minimum speed.5. To stop the vessel, stop the engine. Remove the bolts engaging the clutch when the engine is stopped. Disassemble and inspect the clutch plates for warping and cracking. Damage can occur by having the clutch plates mechanically engaged. Under severe operating conditions, the marine gear should be disassembled and all bearings inspected closely.Engine Jacket Water Pump Failure
If the engine jacket water pump should fail, fresh water can be supplied to the engine jacket using the emergency water system.
Tee Connector (1), Shut Off Valve (2), Emergency Jacket Water Pump (3), Tee Connector (4) & Shut Off Valve (5).1. Stop the engine. If the water pump bearing has failed, the water pump does NOT need to be removed.2. Open valve (2) between the emergency pump and oil cooler connection. 3. Place the diverter valve handle in the EMERGENCY position.4. Start and prime the emergency jacket water pump (3). Allow air to escape from the emergency cooling system lines.5. Check coolant level in the expansion tank. Add coolant if required.6. Start the engine. Always start the engine according to the required Engine Starting procedure described in this manual. Engage marine gear and operate vessel at normal speed. If the engine jacket water coolant is lost (i.e. water line rupture or leak) and an insufficient supply of fresh water is available to replenish the system, raw water may be pumped through the engine.a. Stop the engine and make the necessary water pump and lines connections to pump raw water into the jacket water system and back to the source.b. Remove the temperature regulating thermostats from the regulator housing and install housing cover.c. Start and prime the emergency pump.d. Start the engine and allow to idle at low idle. Always start the engine according to the required Engine Starting procedure described in this manual. Engage the marine gear forward clutch. Operate the engine at the lowest speed for the existing weather conditions.e. Maintain engine temperatures as low as possible to minimize deposits in the engine and corrosion of components. Have the engine jacket water system completely disassembled, cleaned and inspected after reaching port. Replace all parts which are corroded or damaged.Engine Raw Water Pump Failure
