Description
Standard Single Mercury Engine Keyless Ignition with Keyless Stop/Start, Remote Stop/Start, & Ecos CoastKey Standard for Mercury is a full-fledged wireless system with remote Start/Stop, 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 2-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. Features: Keyless Start Wireless Start/Stop Wireless Lanyard Start Panel Engine Box Plug & Play Cable 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.
The obvious advantage of this solution is that you have keyless access to the boat and if there are several people using the boat, everyone has the same access without having to have their own keys. It is easy to change the PIN code to restrict access, for example after renting out the boat.
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.

Marine Safety — frequently asked
- What safety equipment is legally required on my boat?
- Requirements vary by boat length and operating area but generally include a Coast Guard-approved life jacket for each person, fire extinguisher(s) of the correct class, visual distress signals, and a sound-producing device. Confirm the exact list for your boat’s size and where you operate.
- How many life jackets do I need?
- You need at least one properly fitted, Coast Guard-approved life jacket (PFD) for every person aboard, and boats 16 feet and over generally also need a throwable flotation device. Fit matters — a PFD that fits and is worn is what actually saves lives.
- Do marine flares and fire extinguishers expire?
- Yes. Pyrotechnic flares have an expiration date (typically about 42 months) and must be replaced, and fire extinguishers must be within date, charged, and undamaged. Check both on a schedule and replace anything expired — required safety gear only counts if it’s current.
