Looking for Mechanic in Milwaukee WI area

[steved]

I'm a new owner. I'm looking for a mechanic (GOOD GUY) who has experience with the A4. Our boat is a 77 Ericson and I believe the engine is original. It has a knocking sound when in gear beginning around 1200rpm. I need someone to do a general inspection and work with Moyer to correct any issues. Any referals appreciated.
