The 8138 Trolling Valve Interlock is an all mechanical, very simple and inexpensive way to protect your expensive transmissions against damage from throttling up while the transmission is in "troll" mode. Most marine transmission manufacturers require that the transmission NOT be slipped (trolling mode) with anything but idle (or slightly above idle) throttle settings. Our Trolling Valve Interlock accomplishes this using a proven technique.
The interlock system is compatible with most Panish Controls systems, including our famous Series 5000, as well as most types of mechanical systems utilizing standard "33" series push-pull cables. Please note: it is not recommended for use with electronic or hydraulic systems.
This quality unit is CNC machined from marine grade aluminum alloys, and is finished in our white textured powder coating. The moving parts are stainless steel and they ride in oil impregnated bronze bushings for long, maintenance free life.
We offer a variety of methods of controlling the trolling valve, but by far, the most common is with our bulkhead mounted Vernier Control Head. This is a very accurate way to adjust shaft rpm, given the overly sensitive valves typically encountered.
