Re: Proper Performance Engineering
Phnx - I was just reading about the 1957 Mercury Mark 75 (first 6 cylinder outboard and first mercury tested at Lake X).
In 1957 that motor set the world endurance record propelling a runabout over 50,000 miles in 68 3/4 days of continuous day and night running. Refueling on the run . . . the boat maintained an average speed of 30.3 miles per hour.
