Premium Plus Quad Mercury Engine Keyless Ignition with Keyless Stop/Start, Remote Stop/Start, Ecos Rem Trim/Tilt
CoastKey Premium Plus for Mercury is a full-fledged wireless system with remote-controlled Start/Stop and remote-controlled Trim/Tilt in addition to a wireless lanyard function. In addition to the control box, cables, and Start Panel (which is mounted at the steering position), the system is equipped with a 5-button wireless remote-control FOB. In addition to the benefits of using the Start Panel (described under BASIC below), the FOB can be used to switch on the ignition and start and stop the engine wirelessly. When you have the FOB with you, it is not necessary to enter the PIN code to unlock the panel (although you can always start the engine that way).
By wearing the FOB at all times, the boat operator is secured with one of the market’s best wireless lanyard systems, which ensures that the boat stops if you fall overboard.
With Premium Plus, you also have the option to remotely control two extra functions, for example, Trim-Tilt and Windlass. Handy when you get to the boat and can stand on the jetty and tilt down the engine, and start it before getting on board and casting off. This is also useful when launching with a boat trailer.
Features:
- Keyless Start
- Start Panel
- Engine Box
- Plug & Play Cable
- Wireless Lanyard
- Wireless Start/Stop
- Wireless Function Aux 1
- Wireless Function Aux 2
CoastKey is installed instead of, or in parallel with the existing ignition key and you can still use the existing lanyard cord.
CoastKey Basic is the basic version of CoastKey. In addition to the control box and cables, it consists of a Start Panel which is mounted at the steering position. To “unlock” you simply enter a PIN code instead of using an ignition key.
If you have a newer Mercury brand engine, installation is incredibly easy. The CoastKey Start Panel fits right into the same hole as the ignition switch and the connectors on the included cable fit right into the existing wiring harness. Truly PLUG & PLAY.
