Sure Marine Service Inc

Sure Marine Service Inc operates as a marine supply store in Seattle, Washington, holding a 4.9-star rating drawn from 63 customer reviews. The showroom welcomes walk-in visitors Monday through Friday from 8:00 AM to 4:30 PM, offering hands-on consultation for boaters seeking heating, cooling, or galley equipment. This Seattle-based business serves marine customers throughout the Pacific Northwest, providing both products and installation support for recreational and commercial vessels.

What distinguishes Sure Marine Service is its specialization in marine-specific heating systems, carrying an extensive inventory of Webasto diesel heaters, Dometic air conditioning units, Olympia hydronic furnaces, and Spheros diesel heaters alongside related repair components. The business maintains a comprehensive parts inventory including hard-to-find items like propane solenoid switches and Force 10 heater lower units, shipping expedited when customers need heat urgently onboard. Their website features technical resources including wire size charts and dealer catalogs, supporting both DIY installers and professional marine mechanics.

Customer reviews consistently highlight the expertise of team members like Chip and Graham, who have resolved heater issues for multiple boat owners. One reviewer described Chip rebuilding and servicing a Webasto heater with professional handling from start to finish, while another praised Graham for persistent problem-solving on heater diagnostics. The company has handled same-day shipping for emergency heating needs and even resolved a warranty dispute where a customer received a replacement switch after initial confusion about coverage. Multiple reviewers specifically mention finding parts and getting questions answered that other suppliers could not accommodate.
