nissan
I bought the 5 hp 4 stroke, I'm very happy with it, its a gas miser big time! pushes the boat hull speed at half throttle. There are several places one can buy these, online usually has the best price, you can buy one for around 1,000. Tohasu makes both the Nissan and Mercury four strokes under 10 hp, and the prices are usually Tahasu cheepest then Nissan followed by Mercury. When I bought mine a friend bought a Mercury because he wanted to buy American, he paid 650. more than I did, other than the paint there the same motor.
