Outboards & Engines for sale
A good outboard is the difference between a boat that starts every time and a project that never leaves the driveway. On Buoy List you will find outboard motors, trolling motors, and props from owners repowering, parting out, or clearing the shop. Buying local lets you hear a motor run on the hose or in a test tank before any money changes hands.

Frequently asked questions
-
How much does a used outboard motor cost?
- Small portable outboards under 20 horsepower often sell for 500 to 2,500 dollars, mid-range 50 to 115 horsepower motors run 2,500 to 8,000 dollars, and late-model high-horsepower four-strokes over 150 horsepower commonly bring 8,000 to 20,000 dollars or more. Hours, brand, and whether controls and rigging are included drive the price.
-
What should I check when buying a used outboard?
- Run it (on a hose or in a test tank), watch for smooth idle, a steady tell-tale stream, and no excessive smoke, and have a compression test done across all cylinders (numbers should be even). Check the lower unit oil for a milky look that signals water intrusion, inspect the prop and skeg, and confirm it comes with controls, gauges, and a clean title if your state titles motors.
-
Two-stroke or four-stroke outboard?
- Four-strokes are quieter, cleaner, and more fuel efficient, which is why they dominate new sales, but they are heavier and pricier used. Two-strokes are lighter and simpler, and direct-injection models run clean, making them a strong value on the used market. For a light tiller boat, a two-stroke can be ideal; for a bigger rig you run often, a four-stroke usually wins.
-
How many hours is too many on an outboard?
- A well-maintained four-stroke can run 1,500 to 3,000 hours or more, so hours matter less than care. Freshwater use and a documented service history beat low hours on a neglected, saltwater-run motor. Always base your decision on a compression test and how it runs, not the hour meter alone.
-
Will a used outboard fit my boat?
- Match the shaft length to your transom (typically 20 inches for a standard transom, 25 inches for an offshore boat), and confirm the horsepower is within your boat's rated maximum on the capacity plate. Check that the controls, harness, and gauges are compatible or included. When unsure, share your boat's make and transom height with the seller.
