First Impressions of Sierra International MP39100 Ignition Switch Evinrude/Johnson 386545
The Sierra International MP39100 Ignition Switch Evinrude/Johnson 386545 might not be the sexiest piece of gear, but a functional ignition switch is the unsung hero of any boating experience. Without it, you’re dead in the water, and that’s a scenario I’ve experienced far too many times to take lightly. Sierra International promises maximum corrosion protection, a crucial feature in the harsh marine environment, and compatibility with both magneto and conventional ignition systems, making it a versatile replacement option.
I needed a reliable replacement ignition switch for my aging Evinrude outboard after the original one finally gave up the ghost during a fishing trip – leaving me stranded and regretting my life choices. Countless hours spent troubleshooting wiring diagrams and fiddling with corroded connections led me to this specific Sierra International switch. I chose it over cheaper, generic options, hoping that the brand’s reputation for quality and its advertised corrosion resistance would translate into a longer-lasting and more dependable product.
Upon unboxing the Sierra International MP39100 Ignition Switch Evinrude/Johnson 386545, I was immediately impressed by the solid feel and construction. The non-conductive housing eliminates potential shorts, adding an extra layer of safety, while the inner seal between the cylinder lock and contact plate looks like it will do a decent job of keeping moisture out. Compared to the flimsy, all-plastic switch I was replacing, this felt like a significant upgrade.
Initial impressions were overwhelmingly positive; I was genuinely excited to install it and get back on the water. It was a pleasant surprise after dealing with the frustration of the old, failing switch.

First Use Experience
The real test for the Sierra International MP39100 Ignition Switch Evinrude/Johnson 386545 began the moment I installed it on my 1988 Evinrude 70HP outboard. My initial testing took place on the choppy waters of the Puget Sound, during a typical Pacific Northwest drizzly day. Installation was straightforward thanks to its interchangeability with the original Evinrude/Johnson 386545 switch, requiring only basic tools and minimal fiddling.
The engine fired up instantly, a welcome change after weeks of struggling with the faulty old switch. The switch operated smoothly and the Off – Run – Start positions felt firm and positive. There were no issues encountered even though it was wet.
Extended Use & Reliability
After several months of regular use, including numerous fishing trips and weekend cruises, the Sierra International MP39100 Ignition Switch Evinrude/Johnson 386545 has proven its worth. It has been subjected to saltwater spray, constant vibration, and temperature fluctuations with zero issues. The switch still feels as solid as the day I installed it, with no signs of corrosion or degradation.
Maintenance has been minimal; I simply wipe it down occasionally with a damp cloth to remove any salt buildup. This is a far cry from the constant cleaning and lubrication I had to perform on my previous switch just to keep it functioning. This switch has definitely outperformed my expectations and proven itself to be a dependable component of my boat’s electrical system.
