On that note, the engine end is as dependable as what it came from, like the generators I used to run had mazda engines that were basically tanks. The systems that failed were those designed by westerbeke, typically from being under-engineered. What was worse was when I'd talk face to face with the engineers and service rep, bounce a persistent problem off them and have them give me a bs line about what they did to rectify it, knowing full well it still happened on the models they said had the fix.
