CONTROL BOX B77

The Ultraflex B77 control box, single lever with trim, dual action for one engine, fits any boat with an outboard, inboard or sterndrive engine fitted with a hydraulic gear shift. It automatically prevents the gear shift from engaging if the throttle isn't at idle. Built in die-cast aluminium, painted or chrome-plated. Pulling the lever outward disengages the gear shift while warming up the engine. With the X12 safety switch (optional), the engine starts only with the gear shift in neutral.

Compatible with the C2, C8, C14, Mach0 and Mach14 cables; the C5, C16 and Mach5 cables need the K35 adapter kit (item 4242069). Trim models have a switch on the grip that adjusts trim/tilt on outboard engines and sterndrives.
