3. Operation Use the clutch handle to change from FORWARD to NEUTRAL (boat stopped) to REVERSE. {3) Are there abnormal vi bration s or noise? Do not operate at speeds which produce violent vibrations. Depending on t he hull structure, engine and hull resonance may suddenly become great at a certain engine speed range, causing heavy vibrations. Avoid operation in this speed range. If you Shi fting th e c lutch wh i le operating at h ig h s pe ed or not pushing the handle f ull y into position {half c lut ch) will re s utt in damage to cl utch pa rt s and abnormal wear. hear any abnormal sounds, stop the engine and inspect.

if the alarm buzzer sounds during opera- ti on, lower the engine speed immediately, 1. Before using the clutch, be sure to move the governor handle to a l ow speed position (1 000 rpm or less). Move the governor handle to a high speed position after completing clutch operation. r:r:l 2. When changing between FORWARD liil and REVERSE, bring the clutch to NEUTRAL and pause before slowly shifting to the desired position. Do not shift abruptly from FORWARD to REVERSE or vice versa. 3. Move the clutch handle accurately and check the warning lamps, and stop the engine for repairs. (5) Is there wat er, o il , or gas leakage , or are there any loo se bolts?
Check the engine room periodically for any problems. (6) Is there s uff i cient fuel oil in the fu el oil tank ? Replenish fuel oil in advance to avoid running out of fuel during operatlon. fully Into the FORWARD, NEUTRAL, and REVERSE positions. 3.3.4 Ca uti ons During Operation (7) When opera ting the engine at low spe ed for l on g periods of time , race th e engin e on ce every 2 ho urs . Always be on the lookout for problems during engine operation. Pay particular attention to the following: Note: Racing the Engine With the clutch in NEUTRAL, accel- erate from the low speed position to the high speed position and repeat this process about 5 times.
This is done to clean out carbon from the cylinders and the fuel injection valve. {1) Is s uffi ci ent water being discharged fr om the s eawater outlet pipe? If the discharge is small, stop the engine Immediately, identify the cause and repair. {2) Is the ex haust c olour normal? The continuous emission of black exhaust indicates engine overloading. This shortens the engine's life and should be Neglecting to race the engine will result in poor exhaust colour and reduce engine performance. avoided. 30
