Boat Ignition Switch with Key Replacement for Mercury, Replace Boat Engine Ignition Switch with 2 Keys 3 Position 6 Wire Connectors for 87-88107A5

Worked Perfect!

Received the switch in perfect condition and on the date promised. It was easy to install.

My husband bought this and put it in our boat. It fit perfectly and hasn't torn up yet.

Purchased this for a 2005 Mercury Salt Water series 150hp and this replaced the OEM switch perfectly. Wires are all the same, dimensions are really close but the diameter of this switch is slightly larger. I had to modify my bracket a smidge to get it to fit but it was really easy to do and didn't take much effort. After installing, cranked right up and the automatic electric choke worked as well. And it was half the price of the actually mercury OEM part, so that was nice to save a few bucks, because as we all know, boats are just a hole in the water that you dump money into.

Fit out 2005 pontoon perfect. All wire colors matched our boat....i checked with a multimeter just to be sure.

Wires color coded for easy, correct replacement. Well made with epoxy filled and sealed wires to make water proof and provide strain relief on wires exiting switch body. As others have mentioned, needed to very slightly reem out hole as this is just too tight to force through old pass through hole. Also, about a thick 1/4" longer than my old switch but I did have enough clearance. Works perfect. 225hp Merc turns over and starts better than ever. Nice price and quality product.

Looks really nice and good price but there were no directions at all to identify what wires are what. Boat wiring colors don't match so tral and error hooking this one up.

Worked perfectly
