MFS50AETS
Marine Engineer Insight: The Tohatsu MFS50AETS (MPN MFS50AETS) is a rare powerhouse in the short-shaft category. As one of the lightest 50hp outboards available, this 15" short shaft model is specifically engineered for high-performance skiffs and inflatable RIBs that require maximum thrust without the weight penalty of larger engines. Featuring a SOHC 3-cylinder EFI architecture, it provides an exceptional hole-shot and refined fuel efficiency that modern boaters demand.
Compact Power & Class-Leading Weight
The Tohatsu MFS50AETS (MPN: MFS50AETS) brings professional-grade 4-stroke performance to vessels with shorter transoms. By utilizing advanced Electronic Fuel Injection (EFI), this motor delivers precise fuel atomization for instant starting, crisp throttle response, and smooth idling. The streamlined gear case and lightweight pylon design significantly reduce drag, allowing your boat to reach plane faster and maintain higher top-end speeds with ease.
This model comes standard with Power Tilt and Trim, giving the operator full control over the boat's running attitude and shallow water capability from the helm. Despite its compact size, it houses a heavy-duty 21-amp alternator to ensure your marine electronics and accessories are always powered. With Tohatsu’s legendary durability and a stainless steel water pump housing, the MFS50AETS is built to withstand the rigors of both salt and freshwater environments.
