Midwest Marine Supply Co

What Midwest Marine Supply Co does

Midwest Marine Supply Co is a privately held marine parts and supplies distributor founded in 1969 and headquartered at 24300 Jefferson Avenue, St. Clair Shores, Michigan. The company distributes marine parts, equipment, and supplies across 27-28 product categories, including engine and transmission components, electrical systems, plumbing, pumps, steering, refrigeration, fire suppression, anchoring and docking, boat maintenance, tools, paints, and winterization products. Its primary customer segments are individual boat owners, marine service professionals (repair shops, technicians, dealers), and marine dealerships, with operations extending across the Midwest US and into Canada.

The company's commercial operations are conducted through an e-commerce storefront built on Activant inet technology, providing online catalog browsing, shopping cart, checkout, advanced product search (by description, item number, manufacturer, and UPC), and account-based ordering restricted to pre-approved existing clients. Order fulfillment is handled via UPS Ground with same-day processing for in-stock items ordered before 3:00 PM EST, and freight shipping with a noon cutoff for larger orders. The technology stack is functional and established but legacy in nature: there is no mobile app, no public API, no SDK, and no disclosed proprietary features.

Revenue is generated through one-time product sales with no subscription or recurring component. Pricing is opaque — most products display MSRP or "CALL FOR PRICING" rather than published prices, and some items carry core charge pricing typical of marine parts exchange. Customer acquisition is organic through the e-commerce site, and new customer ordering requires account approval, indicating a relationship-based sales model. With 1-10 employees, a single location, and 55 years of continuous operation, the business appears to be a small, owner-operated regional distributor with limited visible investment in growth infrastructure.

Direct peers

• Fisheries Supply: Long-established Pacific Northwest marine and industrial supply distributor with a strong online catalog across engine, electrical, plumbing, and hardware categories. Comparable in being a multi-generational, account-based marine parts distributor serving both retail and B2B customers.
• Jamestown Distributors: Marine distributor specializing in boatbuilding, maintenance, and repair supplies — including epoxy, fasteners, paint, and hardware. Overlaps with Midwest Marine's maintenance and consumables categories and serves similar professional and DIY boater segments.
• Boat Owners Warehouse: Online retailer of marine parts and accessories serving recreational boaters and service professionals, with breadth across engine, electrical, and maintenance categories. Comparable mid-sized online marine parts distributor.

Broad incumbents
