As someone who’s spent countless hours troubleshooting marine engines in less-than-ideal conditions, I understand the importance of having reliable ignition parts, and I’m eager to put this coil through its paces.
My own experience with outboard motors on my old fishing boat – especially when they quit mid-lake – taught me the hard way about electrical system upkeep.

Upon unboxing, the coil felt solid and well-constructed; it was similar in weight and size to the original Yamaha coil I was replacing. The materials appeared to be of good quality, and the overall build seemed robust enough to withstand the harsh marine environment.
Compared to some aftermarket coils I’ve seen, which often look and feel flimsy, the Sierra International 185110 Ignition Coil impressed me with its apparent quality. I considered other options, including sticking with the OEM Yamaha coil, but the Sierra International offered a significant cost savings. Initially, I felt cautiously optimistic; hoping it would live up to its promises.

The engine started smoothly on the first try, even in the chilly morning air; the coil performed flawlessly during several hours of trolling and running at various speeds. The waves were kicking up a bit, spraying water on the engine, but the Sierra International 185110 Ignition Coil didn’t skip a beat.
No issues arose during the first outing, which was a pleasant surprise considering some aftermarket parts can be temperamental. The immediate performance was encouraging, and I appreciated the peace of mind knowing the engine was firing reliably.
