First Impressions of Sierra International 185745 Ignition Coil For Volvo Aq171A/Aq171C/251A, 1988 1992
Nothing sinks a good day on the water faster than a dead engine. And for those of us running classic Volvo Penta AQ171A, AQ171C, or 251A I/O engines from the late 80s and early 90s, a reliable ignition coil is absolutely critical. Sierra International has stepped up to the plate with their 18-5745 Ignition Coil, designed specifically as a replacement for these engines.
My own experience with vintage boats has taught me the hard way that electrical components are often the first to fail. When my AQ171C started sputtering and ultimately died mid-lake last summer, I knew the ignition coil was a prime suspect. I was looking for a direct replacement that wouldn’t require extensive modifications and one that I could trust to get me back on the water reliably.
Upon receiving the Sierra International 185745 Ignition Coil, I was immediately impressed with the solid construction. The coil felt substantial and well-made, not like some of the cheaper aftermarket parts I’ve encountered. My first thought was, “This looks like it can handle the marine environment.”
Compared to some universal coils, this Sierra International coil is designed to be a drop-in replacement, meaning less time wrenching and more time enjoying the boat. Other options I considered included generic automotive coils, but those would have required significant modifications to the wiring and mounting. Ultimately, the promise of a seamless fit and the reputation of Sierra International swayed my decision.
I was cautiously optimistic. I’ve been burned by aftermarket parts before, but this coil had the look and feel of a quality component. Could this Sierra International 185745 Ignition Coil be the solution to my vintage Volvo Penta woes?
