The Mitsu model & serial
numbers are stamped on the block, around the governor. Not easy to find but its there. See below.
Once you have it, google
mitsubish and the engine
model, like mine: L3E. What shows are the non-marine versions of course but you can see the major parts
location and the similarities to the Westy. Vetus egines use exactly the same block as mine.
