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.

Doesn't work
Color: Dark Brown
Not effective for growing lashes. I've used it daily as directed and hoped it would work but there is no change in my lash length or density after months. Not even a "good" mascara for daily aesthetics. Overpriced, would not purchase again.

Eh. It's fine
Color: Black
I feel like this mascara is okay. Not fantastic, not terrible. I like a dramatic lash and this mascara doesn't give me the drama. I have been using it for about a month, so I can't really speak much to how well it helps the lashes grow. I haven't noticed any difference yet. It does flake a bit, but not a lot. Really just okay.

Doesn’t flake or smudge!
Color: Black
The is the first mascara I’ve ever used that truly stays put. I’ve tried several other brands (including many with tubing effects) that advertise smudge proof but aren’t. Worth buying!

Worked Nice
Color: Black
I really like this mascara much better than I thought I would. I'm not a fan of false lashes and since my own lashes are pretty pathetic I've tried just about every mascara out there to find one that at least attempts to make it look like I've actually got lashes. I was skeptical at first but this one actually worked quite well. It has a large brush but that did a good job at really separating and drawing them out so they looked longer and fuller. I also had less issue with overshooting it onto the eye lid/brow area so less Q tip cleanup required. I liked the mascara itself, it went on smoothly and felt nice on my lashes. It wasn't at all clumpy or cakey and was nice and light on. I also didn't have any issue with it flaking off during the day. It is a much higher price point than I typically pay for a single mascara and is not a really large tube, but I did notice I wasn't using as much of it as usual and I do like how it felt and looked on my lashes.
