Sierra MP41040, Ignition Switch - 4 Position Conventional

This product is amazing. This fit our ‘87 Sea Ray Seville and installation was easy and straightforward. To me since we got the boat recently , this switch works way better than the previous switch. The wiring was 1:1 for my specific model did not need to change any of the wiring contacts or modify the wiring in any way. Mine was a combination of 0.25” spade connectors for the ignition and switch wires , however, needed to use the screw connector for the battery wires. I had 3 wires for battery. Also, another thing to note is that our boat has a separate switch for the accessory power for the radio, so there is no need to connect to the accessory connector on the switch. Overall great product and fit exactly in place and works better than before !

Exactly like the original

I had to replace the one that fell apart on the lake. I just took photos and googled brands and this one had the same look and same connectors as the old one. Easy to install and works!

Replaced the ignition switch on my 1999 Sea-Ray boat. Fits and looks and works exactly like the original.

Giving it 4 out of 5 stars because the OEM switch on my 2003 Larson 210 LXI had threaded holes on the terminals and this one does not. At first I was just going to drill and tap the hole in the terminal of the new switch so I could continue using the loop connectors on all the wires running to the old switch but decided against it. The terminals on the new switch were too thin compared to the OEM one to get enough threads tapped so instead I drilled the holes out and put small bolts and lock nuts in there. I also thought about cutting the wires and crimping on push terminals to match the new switch but 2 of the terminals had 3 wires coming to them and another had 2 but one of them was a real heavy gauge. They don't make a push connector small enough for those terminals that will crimp on to that much wire. The bolt on solution worked great and should hold forever with the lock nuts. If you want to go this route put the heads of the screws to the inside and bolt the wires on the outside, that was you have more than enough clearance between each set of wires to prevent any potential shorting.

This is the exact same as the one i replaced in my Malibu LX. It fit right in and was a very easy switch. The key turns smoothly in the ignition.

Worked great. Easy to replace.

I bought this starter switch for our SeaRay when ours was sticking. I tried 2 of the local switches which were marginal at best. I seen this one on Amazon which looked identical to the OEM switch. I know how good Amazon Prime is about returns, so I tried it. If you need a switch that has acc-off-run-start (4 pole) buy this one! It is high quality. Installing was a snap because of the screw poles instead of the blade connector. Talking about Amazon Prime, I ordered this switch at 4pm CST for next day and it was on time. Great Service !! Gadget
