Why choose a used Mariner 15hp outboard motor?
Versatility and value
The Mariner 15hp model has been a long-standing option for small to mid-sized boats: tenders, jon boats, skiffs, inflatables, and even as auxiliary motors for larger craft. One used listing describes a Mariner 15hp (2-stroke) “very strong … runs excellent … perfect for a Boston Whaler type skiff, Big Jon Boat, Gheenoe, barge, pontoon, large inflatable” in the U.S. market.
Buying used means you can get decent power and brand recognition at a significantly lower cost than new. used Mariner 15 hp outboard motor for sale
Parts and support availability
The Mariner line has been popular enough that parts inventories and aftermarket support exist. For example, “Mariner 15 hp outboard motor parts by all engine parts & marineengine.com” lists serial-number ranges and parts availability. That helps reduce the risk of buying used.
Additionally, forums show that earlier models of Mariner 15hp have enjoyed years of reliable use.
Suitable for U.S. boating conditions
In the United States, many boaters seek a 15hp motor that is efficient, easy to maintain, and suitable for lakes, rivers, and coastal waters. A used Mariner 15hp hits that sweet spot: enough power to get you on plane (depending on hull) but light enough for smaller craft and simpler rigging. used Mariner 15 hp outboard motor for sale

Important factors when buying a used Mariner 15hp outboard motor
When you’re looking at a used Mariner 15hp outboard motor for sale, there are several key things to check. We recommend you treat it like a “whole” purchase — motor, lower unit, mounts, controls, propeller (if included) — so you know what you’re getting.
1. Model year & specification
Different versions of the Mariner 15hp exist: older 2-stroke models, newer 4-stroke EFI versions. For example, a Mariner FourStroke 15hp specification shows 15 hp / 11.1 kW, 333 cc displacement, full throttle 5700-6200 rpm.
Determine which version you’re buying: 2-stroke or 4-stroke, manual or electric start, tiller or remote controls. This affects performance, maintenance needs, fuel type, and value.
2. Hours and usage history
As with any used motor, hours of use and how it was used are critical. Was it used in fresh water or salt water? Was it regularly maintained? A unit that sat unused for years might have internal corrosion or seals hardened.
From forum feedback: “If you’re going to view a local 15 hp 2-stroke Mariner … aside from the usual (oil in the gearbox, compression test etc.) … these are brilliant outboards … as long as you are happy with the basic condition of powerhead/gearbox.”
We at Scott Outboard Motors LLC perform internal inspections, compression tests, gearbox checks and present you with a clear condition report. used Mariner 15 hp outboard motor for sale
3. Lower unit and gearcase condition
The lower unit (gearcase) is often overlooked but can be expensive to repair. When buying used:
-
Check lower unit oil for water ingress (milky colour).
-
Check propeller shaft play.
-
Check for damage to the skeg or gearcase housing.
On Mariner 15hp models, forum users flagged the tilt/lock mechanism and gearcase wear as common maintenance items.
We ensure used motors we sell have fresh lower unit oil and no signs of catastrophic gearcase failure.
4. Starting and running condition
Ask for a demonstration if possible, or check startup behaviour and idling: used Mariner 15 hp outboard motor for sale
-
Does the motor cold-start easily?
-
Does it hold a steady idle without excessive smoke (for 4-stroke) or excessive exhaust smoke (for 2-stroke)?
-
Does the water stream out of the cooling jacket consistently?
From forums: “It starts on first pull … the inside of this motor is very clean. I was impressed by the power of this motor.”
If you buy from us, we test-run the motor on water and supply video proof when shipping within the U.S.
5. Fuel / oil configuration (2-stroke vs 4-stroke)
Older Mariner 15hp engines are 2-stroke and require a fuel/oil mix (e.g., 50:1). Newer Mariner 4-stroke versions (EFI) run on straight gasoline, less oil mixing, quieter and generally lower emissions.
Depending on your hull and usage, you may prefer one type over the other. Ensure the listing clearly states which one. used Mariner 15 hp outboard motor for sale
6. Shaft length and mount compatibility
Check shaft length (common short shaft ~15”/381 mm or long shaft ~20”/508 mm). The correct shaft length ensures the anti-ventilation plate is at proper depth and the motor can perform efficiently.
Make sure the motor you buy matches your transom height and mount style. used Mariner 15 hp outboard motor for sale
7. Propeller & rigging
Sometimes used motors are sold without a propeller or with a generic prop. Ask:
-
Is the prop included?
-
Is it correct size and pitch for your hull?
-
Are control cables and tiller handle included (if tiller mount) or are remote controls present?
You don’t want to buy a motor and then have to spend a lot more on rigging before it’s usable.
8. Shipping, warranty & condition disclosure
Since you’re buying used and likely shipping across the U.S., consider:
-
Is the seller experienced in shipping outboards safely (with drain plugs, dry shipping, crate)? used Mariner 15 hp outboard motor for sale
-
Are return or refund policies in place?
-
Does the seller provide a condition report, compression readings, lower unit photos, and if possible a video of the motor running?

FAQs – Frequently Asked Questions
Q1: What does “used Mariner 15hp outboard motor for sale” mean exactly?
A: It means you’re purchasing a pre-owned (second-hand) motor from the manufacturer Mariner (which is part of the Mercury/Mariner line) with a 15 horsepower rating. The listing should include the motor as a complete unit including the powerhead, lower unit, and ideally prop and controls, ready to install. used Mariner 15 hp outboard motor for sale
Q2: Is a Mariner 15hp enough power for my boat?
A: It depends on your hull, load, and usage. For many small boats (e.g., aluminium jon boats, inflatables, skiffs), a 15hp motor is adequate for trolling, cruising, or utility use. If you intend to carry heavy loads, chase top speed, or handle large waters, you may need more. Always check boat manufacturer’s max HP rating and consult a dealer.
Q3: Should I choose 2-stroke or 4-stroke?
A: 2-stroke versions may be lighter and simpler, but require fuel/oil mix, may emit more exhaust, and might be older. 4-stroke (especially EFI) versions usually run on plain gasoline, offer quieter operation, better emissions, easier starting and potentially better fuel economy. For U.S. buyers wanting ease of use, a 4-stroke is often preferred.
Q4: What should I check when buying used?
A: Review hours of use, service history, lower unit gear oil, compression in cylinders, water pump condition, shaft length compatibility, signs of salt-water corrosion. Ask for video of the motor running, inspect for oil leaks, check tilt/trim mechanism, verify propeller condition. Use the checklist above. used Mariner 15 hp outboard motor for sale
Q5: How do shipping and logistics work in the U.S.?
A: At Scott Outboard Motors LLC we handle U.S. shipping coast-to-coast. The used motor is drained of fluids, shipped in a crate or pallet, and insured. We provide condition reports, photos, and you’ll receive tracking. Once you receive the motor, you’ll install fresh oils, connect fuel and controls, and perform a sea trial.
Q6: Is there any warranty or return policy for used motors?
A: Used motors usually sell “as-is”, but some sellers (like us) provide short-term guarantee of start-ability or dispatch condition. We detail any known issues, run the motor before shipment, and support troubleshooting post-sale. Always ask for the specific terms before purchase.
Q7: What about parts and servicing in the U.S.?
A: Because Mariner motors share heritage with Mercury, parts and service are reasonably available across the U.S. Specialized outboard shops, marine dealers, and online parts suppliers stock filters, gaskets, fluids, impellers, and other consumables. As noted, Mariner 15hp parts listings exist. used Mariner 15 hp outboard motor for sale
