I would try & find out if the 2GM has a tractor base engine. Most of those early Yanmar marine engines did AFAIK. There are tractor engine parts available from Taiwan
of japanese quality for much cheaper prices. If you can find tractor parts go for the rebuild would be my choice.
DV20 is a sound engine although heavy, trouble is parts prices are probly worse than Yanmar impossible as it may seem.
Will PM you link to duty cycle report.
Sad alright how built in obsolescence pays, however technology changes rapidly as well.
BTW I think the article that Gordmay posted ( thanks GordMay
sums what duty cycle means pretty good.[/QUOTE]
There is a 3GM industrial model , 3T-70B , I have one amongst my “to do” store of engines waiting for a heat exchanger
. Lower rpm
and hp by a long shot but basically the same engine with a different flywheel housing.... I put a 2 GM housing on it.
