Description

The SD25 is a YANMAR designed and developed sail drive that is custom engineered to match the 1GM10, 2YM15, 3YM20, and 3YM30AE. The SD25 proprietary design connects seamlessly with YANMAR engine’s smaller dedicated marine built housings. This direct connection not only contributes to the compact size of the propulsion system but also reduces the need for adapters or couplings, resulting in a smaller rotational mass and therefore reduced vibration. This purpose-built and complimentary propulsion system maximizes the already efficient sail drive performance.
