To add to the pulling skiers thing (but not with that bracket), motors back then had a lot more low end torque than the next generation (late 1970s/1980s) motors of similar HP, and boats were lighter then too (except for some fiberglass models). When I was 12 years old, I used to ski double with a friend behind my neighbor’s 1958 18 Johnson on a decked Alumacraft model F ( boat rated for 16 HP). As a teen, I routinely pulled 3 teenage girls on skis at the same time behind a 1960 40 HP Johnson running on a 14′ Crestliner aluminum boat rated for 60 HP max. Photo below of me at age 16 in that boat. The motors used a bit more gas than later ones, and needed a bit more TLC, but performance for pullin’ skiers up was great!
