I'm embarking on resurrecting a 1972 AristoCraft w/ a 165
stern drive Mercruiser with a relative next week.

Other than block height, what other quick visual cues to ID the engine? Apparently Mercury used both the 292 block and the 250 block
in the 165 sterndrive series at that time.

We'll be hauling it back home next week and want to dive into
evaluating motor condition and hopefully preparing to start.
Also,
Anyone familiar with the marine exhaust manifold set up?

Ahoy ....!
