I don't know the numbers, Phil, but for an Enya, it wasn't all that heavy.
Like others, I suspect it is near parity with an OS or a Magnum .80
The Enya 80-4C & 60-4C is one of my favorite engines (same casting).
Interestingly enough, I once sat down and did the math to find the
displacement of the 80-4C. It turned out to be .74 cubic inch displacement.
