I also remember the big Scott's as being rather noisy. A high school
buddy of mine had a Crestliner with a 35 hp Scott and it was much louder
than the Evinrudes we ran on our boats.

30 & 33 hp, then 40 hp, there was no 35hp Scott / McCulloch. They were
noisy, the cowls were much simpler than the clamshell OMC brands, but
Scott had fiberglass cowls starting around 1957 and Johnson/Evinrude
caught up a couple of years later. The Johnson/Evinrude 35 & 40 went to a
complicated noise reduction system involving an outer metal shell, & a
large doughnut gasket near the waterline, and an intake silencer in the
lower cowl. They were quieter, the Scott / McCulloch kept the simpler
design that OMC retained for the value-orientated 28hp & 33Hp, and the
Gale 35hp, w/o the full silencing treatment.

I knew it was somewhere in the 30+ hp range. I didn't realize all that was
involved in making the Evinrudes quieter, however. Interesting.
