I'd guess that the inboards were
cheaper to run and had more power than the 2 stroke OBs available in
those days.


One of the boats we had was about an 18 footer with an old, 75hp (I think)
Mercury "Thunderbolt". The engine was huge. The little lake we were on was
about a mile long and maybe 3/4's of a mile wide.

At WOT, that thing could make about 5-6 circuits of the lake before we'd
have to fill up the 6 gallon gas tank again.
