First Use Experience
I tested the Sierra International 186960 Alternator on my son’s 1978 Searay Cuddy Cabin, powered by a Mercury inline-6 engine. Installation was straightforward, thanks to the direct interchangeability with the original Mercury Marine alternator. Everything lined up perfectly, and the included hardware was of good quality.
The initial startup was smooth. The engine idled perfectly, and the voltmeter showed a steady charge. I took the boat out on the lake to conduct some load testing. After several hours on the water, the alternator maintained a stable voltage, even with the fish finder, radio, and running lights all drawing power.
There were no immediately noticeable issues. The alternator ran quietly and efficiently.
