I think that’s what I’ve got and here’s why.
My engine is rated at 37hp by Mitsubishi .. probably some sort of industrial rating. Most of the Mitsu S4L2 engines go to generators and little front end loaders. General industrial use.
Vetus and Westerbeke offer the exact same engine but they rate theirs at 44hp (Westerbeke) and 42hp for the Vetus. All three engines were rated at 3000rpm. So in the case of the three Mitsus no difference in tuning was employed .. I don’t think.
