Step into a first-of-its-kind mobile marine service business specializing in non-invasive flushing and preventative maintenance for marine engine cooling systems. This proprietary process delivers boat owners a cleaner, more cost-effective alternative to traditional teardown repairs—and it’s virtually unmatched in the marketplace.

Despite thousands of recreational and commercial vessels lining the California coast, there are almost no providers offering this essential service. This business holds a unique early-mover advantage, with the opportunity to become the go-to provider in markets that are still wide open.

Fully mobile and home-based, the business includes everything needed to operate from day one: a custom-outfitted service vehicle, specialized fittings and tools, and a trained network of reliable 1099 contractors. The seller operates the business part-time, leaving massive upside for a full-time owner-operator.


Business Highlights:

First-in-market provider with little to no direct competition

Home-based, low-overhead model with no lease required

Sale includes all equipment, vehicle, and custom tools

Skilled 1099 techs already trained in the fieldwork

3-year average revenue of $127K and average SDE of $45K

2023 SDE hit $71K, with the owner working limited hours

Financials include well-documented discretionary add-backs



Scalable Growth Opportunities:

The demand is baked in. Boats of all kinds—from yachts to fishing fleets—require this maintenance regularly.

Expand into new harbors and boating communities along the California coast

Implement digital marketing, SEO, and referral partnerships (none currently active)

Launch subscription service or annual service contracts

Build alliances with brokers, divers, mechanics, and captains

Exhibit at boat shows and marine expos to boost brand exposure

Add weekend hours to handle peak demand

Increase capacity through new techs or service vans

Who This is Best Suited For:

Perfect for a mechanically inclined buyer—whether you're a marine tech, general mechanic, or tradesperson who likes hands-on work. No marine industry experience is required, and the seller is offering full training and transition support.

Poised for Growth with Proven Systems

The seller built this business for flexibility, not scale. But with its streamlined operations, high margins, and unmatched market position, a motivated new owner could turn this into a dominant marine services brand across California and beyond.
