Boat ownership should mean weekends on the water, not months stuck at a marina service bay. If your new or warrantied boat keeps returning to the shop for the same issues, you may be wondering how California’s lemon law applies and whether “days out of service” matter. This guide explains how California law treats boats and what the days-in-the-shop concept means in practice—so you can make informed next steps.
How California Lemon Law Applies to Boats
California’s lemon law lives inside the Song-Beverly Consumer Warranty Act. While the most famous part of the statute—the “New Motor Vehicle” lemon law presumption—focuses on cars and light trucks, the broader Act also protects “consumer goods,” which can include boats purchased or used primarily for personal, family, or household purposes when they are sold with a manufacturer’s warranty. In plain English: if your boat is covered by a warranty and it has a defect the manufacturer can’t fix after a reasonable number of tries, you may have rights under California law.
There’s an important distinction, though. The automatic “lemon law presumption” (like the 30-days-out-of-service or 4-repair-attempt guideposts) applies to new motor vehicles, not boats. Boats typically fall under the consumer-goods portion of the law, which still requires manufacturers to honor their warranties and make timely, effective repairs—but it doesn’t give the same built-in presumption that kicks in for cars. Even without that presumption, repeated repair attempts, safety-related failures, or long stretches in the shop can still be powerful evidence that the warranty hasn’t been honored.
Common boat defects readers encounter include engines that stall or overheat, steering or throttle issues, electrical shorts, failing bilge pumps, fuel system leaks, hull gelcoat or structural problems, and navigation electronics that repeatedly malfunction. If those problems substantially impair the use, value, or safety of the boat and the manufacturer or its authorized repair facility can’t fix them after reasonable opportunities, you may be able to pursue remedies available under California law. The best first steps are to confirm your warranty coverage, work with authorized service centers, and keep thorough records of every visit and communication.
Understanding the Days-in-the-Shop Threshold
You may have heard that “30 days in the shop” makes a vehicle a lemon in California. That benchmark comes from the new motor vehicle lemon law presumption, which generally doesn’t apply to boats. Still, “days out of service” is one of the most persuasive indicators that repairs have not been timely or effective. For boats, there isn’t a single hard-and-fast number set in statute, but extended or repeated downtime can help show that the manufacturer had a reasonable opportunity to fix the issue and failed to do so.
When counting days out of service, include every calendar day your boat is unavailable due to a covered defect—weekends and holidays typically count. If the boat is tied up at a dealership, shipyard, marina service department, or an authorized technician is performing onsite repairs at your slip, note the start and end dates. Delays waiting on manufacturer-approved parts or diagnostic approvals also matter, particularly if the boat remains unusable in the meantime. Keep copies of work orders, time stamps, emails, and texts that show the timeline.
Examples help: if your new inboard repeatedly overheats and the boat spends 45 cumulative days at an authorized yard over the season, or your outboard loses power under load and returns for three repairs plus weeks of parts delays, those facts may support a claim that the warranty wasn’t honored. Safety-related defects—like steering loss, fuel leaks, or electrical fires—often require fewer attempts before they’re considered unreasonable. Because every case is fact-specific, detailed records are essential. Log dates the boat is dropped off and picked up, sea-trial notes, photos or videos of symptoms, and any service bulletins or recalls you’re told about, then consult a professional about your options.
