After the war they came out with a 6 HP motor with a gearshift. My father bought a brand-new 7.5 hp Mercury in 1975 for 0.00 A comparable outboard today would cost about 3 times that much, just as the brand-new 1978 Ford F150 4-wheel-drive pick-up that I almost bought for ,900.00 would, today, cost at least three times as much.Still, the builders of home-made boats are infamously-cheap people, and they often ask me how they can obtain inexpensive outboard power.
