The alternator on my 1982 35hp Johnson is no longer working. My main problem is that I have no idea where or what the alternator looks like. I'm not very familiar w/boat motor mechanics. Could someone please tell me where the alternator is located and what it looks like? Also do I just need to buy a new one or can you get them re-built like a car's alternator. Either way how much $ am I looking at for repairs? Thanks in advance for any help.
