      I laid my 1978 2 stroke mercury v6 to rest only last year and not because it was worn out internally.
      Corrosion and electric components were the deciding factors which no 4 stroke is immune from either.

    There are direct injection two cycle engines that burn equally as clean as a four cycle now and make more power for the same displacement. Plus with the direct injection 2 cycles they’re longer lasting than a 4 cycle cuz of less moving parts still. I would love to see you guys go further into depth on these engines as kinds an up to speed like you guys did with the LS if I remember correctly. However this was an excellent episode as always from Donut!
