Thanks, yep I read that about raw water ingestion so I stop turning over after about 10 seconds. I was hoping to capture that in that video, of course it fired right up then.The 7.6 BTD's use Mitsubishi four-cylinder engines. It's important the valve lash be adjusted per the maintenance schedule. The injectors if over 1000 hours should be sent out and cleaned/tested. You will be amazed how a valve lash and injector service will quite these engines down. Upgrading the water-lift muffler and changing the rubber isolators will also go a long way to quite the boat down. But the most improvement will be a sound enclosure.
Starting the generator - if your setup doesn't have the Monoplex module (looking at your video, it doesn't) then press the Preheat for twenty seconds - it's not really the glow plugs (unless you are in cold climate) that aids in the starting but the lift pump priming the system that gets the generator up and running. The Prestart button does three things - activates the glow plugs, activates the lift pump (that clicking noise), and bypasses the oil pressure switch. Once the machine starts and oil pressure comes above 10 psi the Prestart button can be released.
If, on the other hand, it will not remain running or is spewing black smoke there are other issues. The fact you must crank the engine multiple times when cold lends service is needed. These little engines are very robust.
And, as an edit - never continuously crank these generators; you will fill the cylinders with raw water and that will be a very bad day.
Cold start in this case meant the generator was cold, not the outside air temperature, it was probably in the 60s when I started it Saturday and it took a while.
