The Tohatsu 20HP 4-Stroke Outboard Engine (Short Shaft) is a compact and efficient engine ideal for small boats, dinghies, and RIBs. Featuring a DOHC 3-cylinder engine with EFI technology, it offers smooth acceleration, reliable performance, and excellent fuel economy for freshwater and coastal boating.
Description
The Tohatsu 20HP Short Shaft 4-Stroke Outboard delivers efficient, dependable power in a lightweight and compact design. Its 362cc DOHC 3-cylinder engine ensures smooth operation with minimal vibration, while the Electronic Fuel Injection (EFI) system provides precise fuel delivery, responsive throttle, and improved fuel efficiency.
The 15” (381 mm) short shaft makes this engine suitable for smaller boats or those with shallow transoms, offering proper propeller immersion and stable handling. Key features include electric start, power trim and tilt, and compatibility with remote control or tiller steering, making operation simple and versatile.
Built for durability, the Tohatsu 20HP includes stainless steel components, corrosion-resistant materials, and a reliable water-cooling system, suitable for both freshwater and saltwater use. Its high-output alternator powers onboard electronics, such as lights, navigation systems, and other accessories.
