I have two of these engines in my catamaran
. Sweetest little diesels made.
As has been mentioned already in this thread, there are a couple of ways to stop a diesel. Starve it or decompression.
You should find two stiff mechanical cables
running from the engine to your cockpit
. They originate on the opposite side of the engine from the alternator
. One of these cables
runs to your engine speed control and is your throttle and one is not. The one that's 'not' is your diesel shutoff. It should run to a knob or handle strategically placed, which when pulled, turns off the engine.
Follow the cables from the engine up and you should very quickly figure what goes where. Most boats located the shutoff near the engine controls, but not always. On my boat my stop handles are hidden in a cockpit
The very top of the engine has a square piece of metal about 6" square. This is your valve cover. A lever is mounted in it. Pull the lever up and it dumps compression
. This is not used to stop the engine. Rather it's used to speed bleed (or prime) a slow starting motor
