There is electric and there is electronic. Electric is made from a bunch of electromagnets. Electronics are made up of semiconductors. Electrics are very robust compared to electronics. I once destroyed a personal computer with the static discharge from my hand touching a connector. Electrics would not have have been damaged.



Common rail uses a microprocessor computer and sensors to determine when to inject fuel. A microprocessor has millions of transistors on a chip. If only one is damaged the computer is dead.

Sure, electronics are delicate in that sense and I was writing with the assumption that you have a non CR engine, i.e. no electronics at all, just an electric starter. There is in that situation a chance that lightning and other things can wipe out your electric system and lightning has done just that to boaters in the past. A non-electric way of starting your diesel is lightning proof and pretty bullet proof in general was my point.

Re: Common rail marine diesel engine v standard

We replaced an unreliable Volvo 2003T with a Beta (marinised Kubota) 4 years ago
It is not as smooth as a modern automobile diesel but beats the Volvo
Starts first bang, even in the Arctic and so far trouble free. Bêtas score much better than Volvo’s and better than Yanmars in the SSCA reliability survey
I would avoid electronic diesels in a boat until proof of reliability is available. Recreational diesels are such a tiny market that developers will not put much effort into them.

It’s why I start my beta up and let it idle during severe t storms
