I've never dealt with one of these before so any tips are appreciated.

Boat has a newer engine and I suspect it's been cranked over some extra spins due to a poorly functioning choke on carb.

Having the starter freshened up and wondered if they need to be set up or shimmed for tolerance when re-installed?

It sounds kinda "OK" as used but want to make sure.

Also, can a guy that has been inside a Dana 60 or Napco front end inspect / service the joints in that outdrive? How bigga deal is it?

Prolly need a manual....
