The outboard motor is the heart of most boats on this marketplace, from a kicker on a skiff to a 300-horsepower V8 on an offshore rig.

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 four-strokes over 150 horsepower bring 8,000 to 20,000 dollars or more. Hours, brand, and included controls and rigging drive the price.

What should I check when buying a used outboard motor?

Run it on a hose or in a test tank, confirm a steady tell-tale stream and smooth idle with little smoke, and get a compression test across all cylinders looking for even numbers. Check the lower unit oil for a milky look (water intrusion), inspect the prop and skeg, and confirm it includes controls, gauges, and a clean title where required.

How many hours can an outboard last?

A well-maintained four-stroke can run 1,500 to 3,000 hours or more, so care matters more than the hour count. A documented freshwater motor with service records beats a low-hour neglected saltwater one. Base your decision on compression and how it runs, not just the meter.

Will a used outboard fit my boat?

Match the shaft length to your transom (commonly 20 inches standard, 25 inches for offshore), and confirm the horsepower is within your boat's rated maximum on the capacity plate. Check that controls, harness, and gauges are compatible or included. Share your transom height and boat details with the seller if unsure.
