Try Ken Howden, Ken's Holiday Mobile Marine.  602-510-3552.  He works mostly the east side of town.  He comes right to your house, works on the unit, very reasonable prices.  If you manage to be there when he's working on it you'll learn a lot.

Performance marine in Glendale, Brent is the best mercury mechanic in the state they only work on mercury products

If the outboard is still under warranty (like the drive and 5 from mercury) best to have authorized service center work on it.
