The Tohatsu 20HP 4-Stroke Outboard Engine (Long Shaft) is a reliable and fuel-efficient engine designed for small boats and RIBs. Featuring a DOHC 3-cylinder engine with EFI technology, it provides smooth performance, responsive throttle, and consistent operation for both freshwater and coastal use.
Description
The Tohatsu 20HP Long Shaft 4-Stroke Outboard delivers dependable power in a compact, efficient package. Its 362cc DOHC 3-cylinder engine ensures smooth, low-vibration operation, while the Electronic Fuel Injection (EFI) system provides precise fuel delivery, improved fuel economy, and consistent throttle response.
Designed with a 20” (508 mm) long shaft, it is ideal for boats with deeper transoms, providing optimal propeller immersion, stable handling, and efficient thrust. Features include electric start, power trim and tilt, and compatibility with remote control, allowing easy manoeuvring and simple operation.
Durable and versatile, the Tohatsu 20HP includes stainless steel components, corrosion-resistant materials, and a water-cooling system, suitable for saltwater and freshwater environments. Its high-output alternator powers onboard electronics such as lights, navigation systems, and accessories.
