What M. J. Marine Services does

M. J. Marine Services Limited is a family-run, Hull-based (East Yorkshire, UK) authorized outboard motor dealer and marine engineering business, founded in 2000 by Mark Jones following the closure of Skidom Boat Centre and incorporated as a private limited company in October 2017. The company operates a single workshop at Unit 18, Boulevard Factory Estate (HU3 4AY) and is positioned as Yorkshire, Humberside, and Lincolnshire's "premier outboard dealer," with mobile servicing coverage extending along the UK east coast from Stockton on Tees to Boston.

The core proposition is the full lifecycle support of outboard motors and petrol Mercruiser stern drives: new motor sales (Mercury 2.5–150HP, Tohatsu, Verado, Mercury Marine commercial HOPA range), used motor brokerage with a 30-day warranty, mail-order spare parts across multiple brands (Mercury, Mariner, Yamaha, Honda, Tohatsu, Yanmar), workshop service for 2.5–300HP motors, on-site mobile servicing, and supply/fit of steering and control systems (Ultraflex, Teleflex, Morse, Seastar) plus marine electronics. Diagnostic capability is anchored in proprietary OEM software, including Evinrude etec and Mercury Marine G3 diagnostic tools, distinguishing it from generalist repair shops.

The revenue model combines hardware sales (new and used motors, parts, propellers, consumables such as Quicksilver oils), professional services (workshop and mobile servicing, repairs, installations), and brokerage-style used-motor and used-boat sales on behalf of customers. Pricing is hybrid: unit-priced for parts and consumables displayed in GBP on the e-commerce storefront, quote-based for new motors and service work, and call-out-based for mobile servicing. Distribution is via direct phone sales, a proprietary online shop, an eBay storefront for parts, and physical workshop or on-site installation. The customer base is highly fragmented, predominantly individual recreational boaters with a secondary commercial-marine segment, served through a sales-led motion with no disclosed external capital, headcount, or revenue figures.

Expansion highlights4 records

Direct peers

• Force 4 Chandlery: UK marine chandlery retailer with deep outboard engine parts catalogues, mail-order capability, and a network of branches. Directly comparable on the parts and accessories side, with overlapping supplier relationships across Mercury, Yamaha, and other OEM brands.
• Fox's Marina & Boatyard: UK independent marina and boatyard offering outboard motor sales, servicing, repairs, and parts in Ipswich/Suffolk. Highly comparable as a regional, family-style marine service business combining authorized dealer work, workshop repairs, and parts retail.
• Williams Marine: UK marine retailer with outboard engine sales, parts, and servicing across multiple locations. Comparable as a multi-service marine dealer combining new/used outboards, parts, and workshop repair capability.
• Bates Wharf Marine: UK boat sales and marine service group offering new and used outboards, servicing, and chandlery. Comparable as a regional UK dealer/service network addressing the same recreational boater customer.
• Marine Superstore: UK online-first marine retailer selling outboard parts, accessories, and chandlery with nationwide delivery. Closely comparable on the mail-order parts model that MJ Marine also operates, competing for the same outboard parts search traffic.

Broad incumbents

• West Marine: Largest US marine retailer with extensive outboard parts, accessories, and service infrastructure. Comparable on the parts mail-order and accessories retail model, but operates at much larger scale and across a broader geography than MJ Marine.

Others

• Premier Marinas: UK marina operator with on-site marine services including outboard servicing at multiple south-coast locations. Comparable as an adjacent marina-based service provider serving similar UK leisure boating customers, though operating at marina-operator scale.
• Mercury Marine (Brunswick Corporation): Manufacturer of the Mercury, Mariner, Mercruiser, and Verado product lines that anchor MJ Marine's authorized dealer relationships. Indirectly comparable as the upstream OEM whose dealer terms, warranty policy, and product roadmap materially shape MJ Marine's economics.
• Yamaha Motor UK: Manufacturer of competing outboard motor brands (Yamaha) for which MJ Marine sells parts and accessories on a non-dealer basis. Comparable as an alternative OEM whose UK dealer network competes for the same end customers.
• MDL Marinas: UK marina group offering berthing plus boatyard services including outboard repairs and parts. Comparable as a complementary channel for marine service customers, though marina ownership rather than dealer focus distinguishes it from MJ Marine.
