How often should we be starting up the engines, how long should we run them for and at what RPM?


Start the engines ONLY when you are taking a boat ride, and are about to depart.

Allow them to idle for about 1 min , should be smooth then , and get underway at perhaps 800RPM.

As the engine warms to say 120F , 1200 should do, then when above 140-150F increase the speed till normal cruise is reached.

Real simple , unloaded ideling is never good for a diesel, reaching operating temp with modest loading is the fastest way to warm up.

IF long ideling is required due to local circumstance change oil 2X as often as Da Book sez.
