If I was looking at a Diesel Truck with 60k miles would that be a lot? Well if you figure 60mph that is 1000 Miles on the Engines WITH starts and stops and constant RPM changes, and road vibration, which actually affects engines a lot. In a bot, More consistent RPMs and a lot less vibration because of the water instead of hard surface. Use science, not you Buddy telling you what he "knows" about engines
I see buyers walk away from brilliant boats every week for one single reason: the engine hour meter reads over 3,000.
The industry has conditioned buyers to treat marine diesels like car engines. The logic assumes that low hours equal a pristine, trouble-free machine.
This is the biggest financial trap in the second-hand market.
A marine diesel sitting idle in a marina for 11 months a year is slowly dying. Seals dry out, bores glaze over from light loads, and the internal components seize. Conversely, an engine that has run 5,000 hours at proper operating temperatures is a proven, battle-tested piece of commercial infrastructure.
I wrote a forensic breakdown on exactly why I would rather buy a high-hour, ex-charter engine over a "low-hour" weekend cruiser, and the maths behind the "5,000 Hour Myth".
