Meet the versatile and dependable Tohatsu 90 hp four stroke outboard. In-line 4 cylinder SOHC delivers exceptional torque and power, while still weighing in at only 359 pounds, which makes the BFT 90hp one of the lightest motors in its class. The convenience is even built right into the engine with the built-in freshwater flushing system, for easy routine flushing. To protect against corrosion, the BFT 90 hp has a “Double Sealed” multi-layered paint process, sacrificial anodes and stainless steel technology, along with waterproof connectors, all of which work to enhance your motor’s corrosion protection. Reliability and durability come standard on this high-power, proven-technology four stroke outboard engine.
