! CAUTION

If ambient raw water temperature is above 90 F (32.2 C), it may be necessary to cool the main

engine for at least 20 minutes.

Stopping an engine without a proper cooldown can result in damage to the engine.

Let the port main engine idle for at least 15 minutes to allow cooling water to remove excess heat.

! CAUTION

If the turbocharger lube oil pump fails to operate when engine is shut down and the low turbo oil

pressure alarm sounds, restart the engine immediately. Idle the engine 15 additional minutes

with no load to prevent turbocharger damage.

If engine restart is not possible within 2 minutes, do not restart the engine until the turbocharger

lube oil pump has been restored and the engine has been allowed to cool, or damage to the

turbocharger could result.
