Time to give the motors a kick in the guts.

[cat man do]

I've had these Cummins B3-3 65hp diesels in the cat that i'm building for a year now.

The boat is not in the water and every month i've cranked them over manually for 1/2 a dozen turns and every 4 months hooked up a battery and with the fuel solenoid disconnected given them a quick crank to get oil pressure up.

Now after 12 months it's been suggested to fire 'em up until the temp starts to rise and shut 'em down.

There will be no water running through them at the time, but they do have water in the heat exchanger

My questions are as follows

1] does this sound right?

2] as I dont want to put Diesel in the tanks yet, can I just use a 10 litre plastic tank with a fuel line to motor and a return going back to the tank fill.

3] I would not do this with petrol, but with diesel will it be safe enough?

Obviously I will tighten up all engine mounts an run exhaust.

Please, I'm open to suggestions here from people that have Diesel experiance, not guys like me who have none, but want to have a go.

These cost to much to damage through dodgy advice.

Thanks guys, i'm sure someone here will rise to the challenge.
