Operation NOTE: When the engine is cold, it needs to be warmed up. For further information, see page 40. If the engine is warm and fails to start, open the throttle slightly and try to start the en- gine again. If the engine still fails to start, see page 72.
Operation Avoid accidentally pulling the cord dur- ing normal operation. Loss of engine power means the loss of most steering START control. Also, without engine power, the boat could slow rapidly. This could cause people and objects in the boat to be thrown forward.
Otherwise serious engine dam- swimmers or obstacles in the water near age could occur. Check the oil level and you. add oil if necessary. Consult your Yamaha dealer if the cause for the low ECM01610 oil pressure-warning indicator cannot CAUTION: be found.
