if your diesel engine is not starting then will the injector not fill the cylinder with fuel, If it was a petrol engine you would wait until fuel evaporated but what happens to diesel ????
 
1) Injectors will supply diesel
2) Compression will build heat which evaporates diesel
3) When exhaust valves open and piston moves up, evaporated fuel will be expelled through exhaust (white smoke) .... in preparation for new air and fuel to be injected....and so the cycle goes on....

The biggest worry from prolonged cranking is filling the exhaust with water which could (depending on you exhaust configuration) water lock the engine.

If you are really worried about this I would suggest getting a more experienced person down to the boat.

Yes I will get someone to look at at once I have exhausted all my theories, It is my Genset BTW and I keep the seacock shut for the mo.

If you've been cranking for ages without firing, it might be an idea to change the oil when you do get it going again. Oil with a bit of diesel in it isn't as good as just oil.
 
If it's not starting it's not injecting! Unless there is no compression!

Not necessarily. Injecting at the wrong time, injector hosing, low pressure, broken glo-plugs in an engine designed to use them ... plenty of diesel might be washing around, but no bang!
