F 90

Brief Summary

This 90-hp 4-stroke outboard has enough muscle to move your 1000-lb. boat at over 40 mph and give you 5.75 mpg at best cruise. How much more horsepower do you need? How much more fuel do you need to burn? This relatively new engine from Yamaha has four cylinders, DOHC, fuel injection, 20” and 25” shafts and weighs 369 lb, according to the company.
