Hi all, me again. Thank you for helping in advance. And thanks for the help with the ignition.
For reference: Mercruiser Serial 0L692104 5.7l MCM Thunderbolt V.
I'm now replacing the starter and alternator. The starter died on us at the lake today. I took it down to Advance Auto and they put it on a tester and said she failed their testing machine.
Question is, which parts do I replace with? Both the starter and alternator are Arco, so obviously not original. I can put back in, or would I be better off going with Sierra or Quicksilver (which I assume is Mercury OEM?)
Then - these sites that you put your serial number in and find your part.... they list one Mercury OEM part but it says it has an offset bolt pattern. Then they show a Sierra part and the Arco I pulled out. The one I pulled out was the Arco 30470. According to this website that has a staggard bolt pattern.

(and is there a good site from which to order?)
So can I just buy the Mercruiser OEM part? Is staggered the same as the offset?
And, this may be a matter of opinion, but is OEM better than Sierra and sierra better than Arco? Or are they all about the same?
I am also adding a second battery, starter, and house. Is there any benefit to getting a higher amp alternator? And is there such a thing for this motor? My searches have not come up with any good information. I love running the boat around the lake and through the river channel, but the boys like to stop and fish or swim.
I love wrenching as much as I love cars and boats, but I am beginning to yearn for a little more boating time.
