I was going to suggest the fuel pump diaphragm but wheels beat me to it.

 

As an aside a really good solution to the smoky transom is to cut 300 or 400 off the leg of an old wetsuit and clamp it to the exhaust outlet. The wetsuit I used was a really thick one with material on both sides of the rubber - works a treat and adds a bit of safety from water back into the engine in a following sea.

If you have a high enough elbow in the exhaust water shouldnt be able to back flow,we had a valve on the outlet for the just incase scenario. Trick was to remember to open it before starting.

Yes high elbow is good but not a guarantee. Valve is pain in butt. The wetsuit is another help for backflow prevention but the main purpose of the wetsuit is to stop the black transom - works a treat.

It is called a goose neck and it is essential to have in any exhaust installation. It does two things. It stops water from being driven back into a non operating engine from waves hitting the Transom. It creates a slight restriction due to the water build up and then as pressure overcomes the water, it blows the water out, expelling nearly all of it so as the exhaust is fully emptied of water.

As you were. False alarm. Someone misread dipstick. Bottoms have been kicked, people fired, hopefully a lesson learnt. Sorry. Thank you.

Good drill folks. Nice to know we are now just that little bit more prepared for a real event. Everyone can stand down and go back to their normal routine. No complacency though. Stay prepared. Keep those oil changes and filters up. You just never know when a real event may take place ;-)

Any opinions as to Lombardini marine diesels?
I admit to a probably unfounded prejudice against lightweight high revving engines but could tolerate being corrected, especially one in a canal boat that we like with 80 hours on it.
