Ultraflex B73 Dual-Function Top-Mount Throttle Control

The B73 throttle control by Ultraflex is a single-lever, top-mount throttle designed for controlling throttle and gears in boats with inboard engines. Thanks to its dual-function design (one lever operates both the throttle and gear shift), it provides ease and precision in maneuvering the boat. The main components of the throttle are made of marine aluminum protected with a powder coating, while the lever is chrome-plated for higher corrosion resistance. It is equipped with a pull-out handle function for engine warm-up at idle (warm-up), a lock to prevent accidental gear engagement, and an optional neutral safety switch (X12) that enhances safety by preventing engine start in gear. The product complies with the EN ISO 11547 standard when used with a safety switch.
