Uflex B310B Side Mount Single Lever Control with Trim, Black

The Uflex B310B is a mechanical side mount single lever control for boats, combining throttle and shift into one lever for outboard, sterndrive, and inboard applications. It is built with a positive lock-in neutral position and an integrated trim switch, letting the operator trim the drive or engine directly from the control handle without reaching for a separate switch. The lever assembly uses an aluminum handle for durability under regular marine use, and the housing is finished in black.

The universal control design accepts 33C Universal style cable, and OMC Johnson/Evinrude cables connect with the adapters included in the box. For Mercury Gen I cable setups, the control can be connected with the addition of a K35 connection kit (sold separately). This flexibility makes the B310B a straightforward upgrade or replacement control box for a wide range of single-engine helm stations.
