Well after nearly getting lynched on this board because I was running an automotive starter in my I/O. I ordered a marine unit as well as an alternator from these guys.
Total cost for both starter and alternator was $104 plus $14 to ship to TX.
He had several options to choose from and I decided to save some money and get the remans. The guy seemed really knowledgable on I/O engines. Not sure if they sell outboard stuff but he sure knew his stuff about the I/Os.
Additionally I talked to him about running the auto starter and he said. That honestly for that particular starter its not such a big deal he said that both the marine and auto units are sealed and that the marine one only has one additionaly seal on the shaft.
I got the marine one anyway.
Just thought I'd plug these guys since they were really helpful. As I had no part number on the alternator yet they knew exactly which one it was. This was the third place I called and the others had no clue.
