Re: 75 hp Evinrude Starflite
1962 75hp Evinrude/Johnson...... Weight, approx 247 lbs.
Average speed, mounted on a 17' fiberglass boat:
Approx 37 mph.
Gas usage when set up properly:
At full throttle, 6 gal in 45 minutes (37 mph approx)
At crusing range, 6 gal in 1.5 hours (30 mph approx)
Crusing range is full throttle applied, then drop back to approx 3/4 throttle. This results in having the spark advance still at the full setting BUT drops the throttle butterfly setting to approx its 3/4 setting.
