    I have only seen one mention of this brand. I am likely going to buy a S-270 V-6 270hp diesel for my 26 Shamrock. I can get it for around 22k with a gear last check.

    I understand these engines are all over the world outside of N.A. but there was a 31'Bertram that had a pair put in it but I can't track it down.

    I saw a bayou jet boat company use them in a military style craft.

    That's all I can find here and no solid reviews.

    Does anyone have any real world experience or close knowledge about them?

    A yanmar will cost me double. This thing weighs less than gas equivalent. Sound db about the same as gas.

    This boat had a 210hp Cummins as an option, but no way could i listen to that thing bang away and the weight, omg.

    Unless I hear it has crazy issues, I think I am going to pull the trigger on it.

    Anyone? Anyone?

    Never heard of them until now… all it takes is weak sales for the US distributor to fold and parts will become an issue. If you intend on keeping the boat a long time resale value doesn’t matter otherwise unknown marine engine will be a turn off. Yes I know Hyundai is a big company but still unknown in the marine market here. And considering their disastrous gas engine failures a few years back…

    saving weight is nice but too light is not what you want in a marine diesel

    My MAN rep sell those in S FL. Been selling, installing & servicing them for years.
    I have been doing business with Performance Diesel for many years also.
    IMO good package, good shop.

    With that said, you also have to realize, this is not a big Cummins, Cat or Detroit with monster crank journals;
    IMO, it may not see a long life as these usual monsters do.

    Probably a guide to start with; Ensure there is a good service tech near where your boat is based.
    Same advice I give regarding MAN engines.
