MD 90

Tohatsu offers four outboards from 90 to 40 hp in our highly praised new generation of direct injection outboards. Both the 90 and 70 are much lighter in weight than competitive horsepower 4-strokes and other direct injection outboards. These Tohatsu outboards provide exceptionally smooth operation and outstanding performance.

The 90 and 70 TLDI® provide significant increases in fuel and oil economy while also providing a decrease in hydrocarbon emissions through the exhaust -73% lower levels of HC+NOx. This in turn gives you a cleaner, quieter boat ride at a lower operating cost. And loaded with features usually associated with larger outboards, the 90 and 70 TLDI® aim to please demanding boaters everywhere.
