Was running across the lake to weigh in tonight and my motor gradually started loosing speed, then ultimately died. Volt gauge was dead and lights were going dim. Thought I lost the cranking battery, so I swapped in a troller, and it did nothing, but they were run hard. Had someone pull me in. Got home to find the 6 bolts on top of the compressor had sheared off and the pulley and belt fell off. I never heard a thing or noticed much difference except for a small loss of speed. Looks like there is no damage other than the broken bolts, but I'm wondering if I should go ahead and replace the pulley along with the bolts, or just put it back on. It doesn't seem to be the tightest fit, tolerance wise, so maybe that was the reason? Do these bolts normally come loose? Anything else I should look for before repairing? Common problem? Didn't see anything in the search.
