How Many Hours Will My Marine Diesel Last?

Often reading about Marine Engines, you can get conflicting information on how many hours an engine will genuinely last. Here's a couple of things to consider when taking in this information.

I’m in love with Gardener engines, let’s hear your opinions.
Good channel, and well spoken without arm’s and um’s well done, your worth listening to.

Question: do you know the service life of those giant 16 cylinder mtu marine deisels that they fit into custom sportfishing yachts? Just curious as to when it makes sense to replace them as opposed to refit them. Thanks.

Buy a boat with a Cummins engine, run it at cruise speeds, do routine maintenance at right times and you should get at least 10, 000 hours from that engine.

Hi Aaron. Love your videos. I'm a brand spanker, just getting into boating, I want a live aboard boat to slowly improve it. I have a chance of a Gallart 11 MY 2000 going very cheap the reason being it was submerged on a slipway in Spain and the engines dont work and it needs the electrics sorting. The engines are Catterpillar 320 cv Diesels are they completley F###ed or could they be restored? keep the videos coming. Thanks.

What is "full throttle"? High idle - maximum governed no-load speed? Or full load speed? The loaded speed and condition for "max power"? Or peak torque overload i.e. the engine "lugged"?

"Recreational" engine "ratings" are useless for all but "throwaway" engines like "marine" Cummins 6BTAs.

What are the most reliable marine Diesel engines? Thank you

really great topic 👍🏼 but video is too short and I think a lot of info is missing, maybe some comparisons between the brands lie CAT and others. In your conclusion I would have liked to now how long a diesel engine would last if properly maintained etc, but nevertheless thanks.

Are engines derated by reducing the max fuel? Or is a smaller prop that will never load an engine to its max HP? And therefore derating it's hp I know ford Lehman's are rec rated to 120hp and 80hp for commercial
