Here is a picture of one of my 25E Mercs.
No quickie,....SIGH,...But I do have a complete "Bay Kit", and all the remote controls & related goodies.
My other one is an earlier one, but has the same starter - not a "swing Bendix" starter.
Did Mercury put out the "Bay Kit", or did the Mark 25 have a long shaft DSH option??
I think I've seen a long shaft DSH, but don't recall if it was a Mk 25 or Mk20??
