Mainship 34T Engines

[CaptKevin]

I am considering a Mainship 34T in the 2005-2009 range, have looked at a few and noticed the older ones have a Yanmar 370 while maybe around 2007 they changed to a Yanmar 380. Any input on which might be a better motor in terms of efficiency and longevity would be appreciated. Thanks

I owned a 2006 34T and used it for about five years. It had the older 370 engine that was great.The 380 was a modification of the 370 which may have been based on common rail injection. I am sure it was a great engine as well.

Among other things, make sure it will hit rated rpm and a bit- 3,350 rpm at wot and don’t run it more than 2,800 rpm continuously.

My 2008 has the 370 and it has been trouble free.
I doubt the performance difference would be significant. I'd buy either one based on boat condition & maint history.

Thank you for your advice. Still looking and evaluating the two boats
