Stopping the engine immediately after it has been working under load can result in overheating and accelerated wear of the engine components.If the engine has been operating at high rpm and/or high loads, run at low idle for at least three minutes to reduce and stabilize internal engine temperature before stopping the engine.Avoiding hot engine shutdowns will maximize turbocharger shaft and bearing life.
Note: Individual applications will have different control systems. Follow the OEM recommendations or the instructions for stopping the vessel.
Reduce engine rpm to low idle. Shift the marine transmission to the NEUTRAL position and secure the vessel.
