Frequently Asked Questions
Where do I bring my boat for service?
Service and parts are at 157 Enterprise Drive in Chatham, not at the marina. If your boat is in the water at Outermost Harbor, our crew hauls it and brings it to Enterprise Drive for you — just fill out the service request form and note where the boat is.
Are the marina and the service center at the same address?
No. The marina, slips, moorings, fuel dock and tours are at 83 Seagull Road on Chatham Harbor. The Parts & Service department is a separate shop at 157 Enterprise Drive, about five minutes away by car. Both share one phone number, 508-945-2030 — press 2 for Parts & Service.
What are the Parts & Service hours?
Monday through Friday, 8:00 AM to 4:30 PM, year-round. The service department is closed on weekends, even when the marina is open.
Do I need an appointment?
Yes. Every boat coming in for service needs a service request submitted online — that is how we schedule the haul and shop time. The parts counter is walk-in during business hours.
