Shop Mariner outboards for sale online
Buy a Mariner outboard online and have it freighted to you, rigged and ready to hang. Every Mariner outboard motor we sell is used, priced on condition, and listed with its shaft length in the title so you can shop straight to the ones that fit your transom.
Order through the product page or call and we will size the engine to your boat first. Send us the transom measurement and the hull model before you buy, because shaft length is the one specification that makes an engine either usable or scrap to you.
Used Mariner outboard motors for sale at below Mercury money
Here is the reason to buy one. Mariner was Mercury’s companion brand, and the engines are Mercury underneath. Same components, same parts bin, same nationwide Mercury dealer network for service. What you do not pay for is the badge.
That gap is the whole opportunity. Used Mariner outboard motors for sale trade below an identical Mercury of the same year and horsepower, and nothing about the hardware is different. If you are buying an engine to keep and run rather than to flip, you are simply paying less for the same thing.
Check these before you buy any Mariner outboard motors listing, here or anywhere:
- Compression on every cylinder, written down rather than described.
- Corrosion at the midsection, transom bracket and trim rams, which is where salt shows first.
- Whether controls, harness, prop and gauges are included, because a bare engine costs more than it looks once you rig it.
- The serial number, which tells a Mercury dealer exactly what parts to order.
We list all of that against each engine and will send more photographs of any area before you commit.
Buy Mariner outboard engines for sale by size
Shop by the power your transom is rated for.
The small Mariner motors outboard range suits tenders, dinghies, jon boats and kickers. These are light enough to carry and cheap enough to buy outright, and they are the engines that move fastest off this page.
The midrange covers repowers on aluminum fishing hulls, small pontoons and skiffs. This is where a Mariner outboard for sale saves you the most against a comparable Mercury.
Larger Mariner engines outboard of the midrange go on bay boats and bigger aluminum hulls. Treat one as a Mercury of the same year when you are checking specifications, because that is what it is.
Buy a Mercury Mariner outboard with live parts support
This is what separates a Mariner from every other discontinued outboard brand. Parts and service run through the Mercury dealer network, because Mercury Marine is still in business and still makes the components.
Buy a dead brand from a dead manufacturer and you gamble on parts. Buy a Mercury Mariner outboard and you are buying into a live supply chain at a discontinued brand’s price. Mercury Mariner outboard motors are catalogued by serial rather than by badge, so a Mariner mercury outboard orders parts exactly like the Mercury it is. Mercury Mariner outboard serial numbers identify the exact build, so any Mercury dealer can order against it without guesswork.
Get the serial from the seller before you agree a price. On a Mercury Mariner outboard motor it is the only identifier that matters.
Mariner outboard sales and pricing
Mariner outboard sales here are priced on hours, rigging and shaft length, never on the badge. A 25 inch shaft fits fewer boats, so those engines list below an equivalent 20 inch unit. An engine sold complete with controls and harness carries a premium that still works out cheaper than buying those parts separately.
Cross shop us against the Mercury equivalent and the Mariner will come in under it every time. Cross shop against another orphaned brand and the Mariner wins on parts availability.

Buy Mariner outboards online, shipped nationwide
We ship curbside on liftgate freight, crated for the larger engines, quoted by weight and destination at checkout. Most buyers never visit us, and there is no Mariner dealer network to visit anyway, so ordering is the route to the engine you actually want rather than whatever sits locally.
Cross shopping is welcome. We also stock Mercury outboards for sale and Yamaha outboard motors, both still in production, and Johnson outboard motors and Evinrude outboard motors if you are shopping the discontinued brands on price.
Frequently asked questions
Who makes Mariner outboard motors and who makes Mariner outboard engines?
Brunswick, the parent company of Mercury Marine. Larger Mariners were badge-engineered Mercurys. Many smaller ones were built by Yamaha under a joint venture that ran from the 1970s until the FTC required Brunswick to divest its Yamaha stake.
Are Mariner and Mercury outboards the same engines?
Across most of the range and most years, yes. Same company, same assembly lines, same parts. The exception is the small Yamaha-built models from the earlier years.
Can you still get parts for a Mariner outboard?
Yes, through the nationwide Mercury dealer network, because the engines are Mercury underneath. This is the brand’s biggest advantage over other discontinued outboards.
How do I find out what my Mariner is worth?
Start from the equivalent Mercury of the same year and horsepower, then take off the badge discount. Hours, shaft length and included rigging move it from there.
What should I check before buying a used Mariner?
Compression on every cylinder, corrosion at the midsection and trim rams, whether rigging is included, and the serial number. Get all four before agreeing a price.
Why is a Mariner cheaper than the same Mercury?
Nobody markets the badge any more and resale is weaker. The hardware is unchanged, which is exactly why it is worth buying if you plan to keep the engine.
How much does it cost to ship an outboard motor?
Freight is quoted by weight and destination. Outboards ship curbside on a liftgate truck rather than by parcel carrier, and larger engines go crated.
