Yanmar introduces new stern drive system
Technical details
Producer: Yanmar (JP)

The ZT350 is an all-new sterndrive, designed and manufactured by Yanmar Marine for use with its BY and LP series diesel engines. The quiet, hydrodynamic ZT350 has a new type of hydraulic clutch for smooth operation, precision-forged gears to add durability, plus two counter-rotating propellers to maximise acceleration and enable tight-hold tracking. Its large rudder dimensions allow superior handling on single and twin-engine boats. Weight with propellers is just 112kg.
With maximum power 350mhp (257kW) at 3,800rpm input the available gear ratios are 1.65 and 1.78. At a maximum 260mhp (191kW) at 4,000rpm, gearing is 1.97 or 2.18. Aimed at the repowering market as well as new craft, the new Yanmar drive has the same installation dimensions as compatible units currently available in the market. (yanmarmarine.com)
