The Tohatsu 90HP 4-Stroke Outboard Engine (Long Shaft) is a high-performance, fuel-efficient engine designed for mid-sized boats and offshore use. Featuring DOHC 4-cylinder powerhead with EFI technology, it delivers smooth acceleration, reliable thrust, and low running costs, making it ideal for RIBs, fishing boats, and coastal cruising vessels.
Description
The Tohatsu 90HP Long Shaft 4-Stroke Outboard combines power, reliability, and efficiency in a compact design. Its 1.5L DOHC 4-cylinder engine ensures smooth operation, minimal vibration, and excellent throttle response. The Electronic Fuel Injection (EFI) system provides consistent fuel delivery, superior fuel efficiency, and reduced emissions compared to carbureted engines.
With a 20” (508 mm) long shaft, the engine is suitable for deeper transom boats, providing optimal propeller immersion and stable handling. It features electric start, power trim and tilt, and remote control compatibility, making operation convenient and user-friendly.
Built to withstand marine environments, the Tohatsu 90HP includes stainless steel components, corrosion-resistant coatings, and a robust water-cooling system. A high-output alternator supports onboard electronics, ensuring reliable power for navigation systems, lights, and additional accessories.
