10 year old boat

Dont shoot the messenger.
Far from wishing to do that, M.
It's just that in the marine industry, I heard too many stories from the pros which eventually proved to be just that, stories.
And in a few occasions (rather remarkable ones btw, but it would take too long to explain), what I objected to them based on gut feeling alone eventually proved 100% correct.

Btw, I'm well aware that using blocks produced by a competitor is normal in the engine industry - just think of the smaller Cat engines, which are actually built by the former Aifo/Iveco (now FPT).
But that's essentially public domain, because even if obviously Cat is not advertising their product as sourced by someone else, it's practically impossible to keep these things under wraps in the internet era.
And for the latest MAN V8/V12 blocks, aside from my previous "common sense-based" reasoning, I'd be interested to hear if anyone can find the slightest hint of this Cummins sourcing anywhere on the web, because I did try (well, without loosing my sleep over it, admittedly!) and I couldn't.

Regardless, glad to hear that your engines are performing well.
Actually, also mine do, so far - and it's very obvious that I hope they will, for another 20 years or so...! :)
Otoh, as you might remember, I wasn't exactly impressed by a few construction details which I had a chance to check first hand.

Interesting to read also your update ref. Cat support (lack of).
I'm not sure that would be sufficient to make me dismiss my preference for C32 engines, whose reputation is legendary in their power node in spite of any issues Porto might have found by googling around.
But that's just a theoretical doubt anyway, since my lottery boat is very unlikely to materialize anytime soon - not least because I never bought a lottery ticket in my whole life, and never will! :rolleyes:

It is a specific problem that Cat have in the construction machinery market where engine emissions regulations are well ahead of the marine engine market. Cat have been struggling to deliver engines to meet the latest emissions standards and the emissions handling components on many of their engines have proved troublesome. On top of that, the way their service and spares set up is now organised in Europe means that their after sales service is almost a standing joke. Nothing fundamentally wrong with their engines and personally I wouldnt hesitate to buy a Cat engined boat but then in the marine industry, service expectations are much lower and the engines dont have DPF equipment bolted to them
