To my knowledge, they are the only Johnson place around.
Tom in their parts department is extremely knowledgeable. They don't work on anything older than 1980. Mine is a 1976 and he was very helpful in giving me advice and suggestions on doing it myself. They don't have much of a store, but he can get you parts the next day. If you are looking for a store with general boating supplies, then Bass Pro Shops Outdoor World at Discover Mills is the place to go.
Hope this helps.
