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.

Solid Value 14 AWG Cable, but Jacket Design Could Be Improved
Size: 200-Foot, Style: 14-Gauge
This Amazon Basics 14-gauge speaker wire gets the job done at a very competitive price—under $0.15 per foot for the 200-foot spool. I’m using it for my surround sound speakers, and electrically, it performs just fine for that purpose. Whether it’s truly 99.9% oxygen-free copper (OFC) is hard to verify, but for my needs, it works well. One major downside is the non-round cable jacket design. There are no internal fillers to keep the wire shape consistent, which makes stripping the outer jacket more difficult than it needs to be. Because of the uneven shape, it’s easy to accidentally nick or cut the insulation on the conductors inside while trying to strip it. Including fillers or a more robust outer jacket would make this product significantly better. On the plus side, the cable has printed numbering along one conductor, which makes it easier to measure and cut lengths accurately—definitely a helpful touch for multi-speaker setups. In short, this is a cost-effective solution for basic speaker wiring, but the cable construction could be improved to make handling and prep easier. Still, for the price, it’s hard to complain too much.

Exceeded my expectations in every way.
Size: 200-Foot, Style: 14-Gauge, Size: 200-Foot, Style: 14-Gauge
Great quality solid copper cables. None of the local stores, such as Walmart or Autozone had Any real copper cables at all. All offerings were CCA dual-conductor cables that are essentially 95% aluminum. 2/3rd of available options had Packaging that didn't openly disclose this fact. It took time researching each "high-performance", or "professional grade" audio cables they had in stock. Perhaps, there's no regulations that require manufacturers to to make any reference clarifying that the product isn't pure copper. It was surprisingly misleading. Amazon Basic branded cables are as good as the best cables you cables you can buy elsewhere online. 14 Gauge us about as thick as you could reasonably use at home without it becoming a major annoying mess. Great price as well. Made in Vietnam - is just the icing on the cake. Ordered the "used" option. Cables were brand new, the coil was slightly banged up in shipping and dusty, thus the 15% discount
