Having another engine problem and this time it appears to be the alternator. Anyone know the best place to find a new Mercury alternator part# 8M0064020? Also this is relatively simple to replace correct? And I found a few used ones on Ebay is that an option or just asking for problems? Thank you.Last edited by aluislugo on July 26th, 2016, 4:40 pm, edited 1 time in total.
