Since 1979, the Porter family has been fine tuning its reputation for precision work on Mercury and MerCruiser engines. Veteran mechanics are certified on all 56 outboard models and the 44 MerCruiser engines on the market. Two generations of Porters run a professional, hands-on operation which includes repowers, parts, service and a wide range of other repairs. Nestled in a protected, deep water harbor one mile from the Bay, this marina is as friendly and dependable as your favorite neighborhood pub.
