These motors have either been meticulously maintained or professionally restored. They often include recent major service, new components, and sometimes come with a limited warranty from specialty dealers.

Factors That Drastically Influence Price

Several key factors can significantly impact the asking price of a 115 Johnson outboard:

Model Year & Series: Later models (1990s) typically command higher prices due to design refinements and generally fewer years of wear. The “Loop Charged” models from the mid-80s onward are particularly valued for their improved efficiency.
Condition & Hours: This is the single most important pricing factor. A motor with verified low hours and excellent maintenance history can be worth twice as much as a high-hour, neglected unit.
Saltwater vs. Freshwater Use: Freshwater-only motors typically sell for a 15-25% premium. Saltwater exposure accelerates corrosion, even on well-maintained engines.
Included Accessories: A complete package with controls, wiring harness, prop, and instrumentation adds significant value—often $300-$800 compared to a motor-only sale.

Where to Find a 115 Johnson Outboard for Sale

Online Marketplaces (eBay, Facebook Marketplace)

Online platforms offer the widest selection but require careful navigation. eBay often has both auction and “Buy It Now” options, with the advantage of buyer protection programs. Facebook Marketplace provides more local options but with fewer buyer safeguards.

Pros: Extensive selection, ability to compare prices, sometimes detailed photos and descriptions.

Cons: Potential for scams, inability to personally inspect before purchase, shipping costs for heavy items can be substantial.

Specialty Marine Forums & Classifieds (The “Insider” Spot)

For those in the know, specialized marine communities often yield the best finds. Websites like The Hull Truth, MarineEngine.com, and iBoats forums have dedicated classified sections where enthusiasts sell quality equipment.

Pros: Knowledgeable sellers, often better-maintained equipment, community feedback on sellers.

Cons: Smaller selection, requires regular monitoring, may need to travel for pickup.

Local Marinas & Boat Shops

Don’t underestimate the value of local marine businesses. Many marina operators and boat repair shops take older motors in trade and refurbish them for resale.

Pros: Can inspect in person, often recently serviced, may offer limited warranty, establishes local relationship for future service.

Cons: Typically higher prices, limited selection, may not have exactly what you’re looking for.

Expert Tips: Your Pre-Purchase Inspection Checklist

The Visual Inspection

Before even considering a compression test or water trial, conduct a thorough visual examination:

Corrosion Check: Pay special attention to the lower unit, cooling passages, and mounting brackets. Significant pitting or corrosion indicates saltwater use and potential future problems.
Crack Inspection: Examine the gearcase housing and powerhead for any hairline cracks or repaired areas. Use a flashlight for better visibility in tight spaces.
Propeller Condition: A damaged prop suggests possible impact that could have damaged the lower unit or driveshaft. Look for bends, cracks, or significant wear.
Electrical Connections: Check for corroded or brittle wiring, which can be expensive and time-consuming to replace.

The Mechanical Inspection (If Possible)

If you have the opportunity to conduct or witness mechanical testing, prioritize these assessments:

Compression Test: This is the single most important test for any two-stroke engine. All cylinders should read within 10-15% of each other. For a 115 Johnson, expect readings between 100-130 PSI per cylinder. Significant variance indicates worn rings, piston, or cylinder damage.
Spark Check: Remove each spark plug and ground it against the powerhead while cranking the engine. A strong, bright blue spark indicates healthy ignition components.
Lower Unit Oil Inspection: Drain a small amount of gear oil from the lower unit. Milky, creamy oil indicates water intrusion—a potentially expensive repair requiring seal replacement.
Fuel System Check: Look for signs of old fuel, varnish, or debris in the carburetor bowls and fuel lines.

Questions to Ask the Seller

Your conversation with the seller can reveal as much as the physical inspection. Always ask these critical questions:

“When was the last time this motor was run, and how does it perform?”
“Can you provide any service records or receipts for parts replaced?”
“What is the history of this motor? How long have you owned it?”
“Has it ever been used in saltwater, and if so, was it flushed regularly?”
“Are you the original owner? If not, what do you know about its history?”
“What is the reason for selling?”
“Are there any known issues or quirks I should be aware of?”

Considering the Alternatives: Johnson vs. The Competition

Johnson 115 vs. Evinrude 115

For many buyers, the Evinrude 115 presents an interesting alternative—or essentially the same option. As sister companies under the OMC (Outboard Marine Corporation) umbrella, Johnson and Evinrude often shared identical powerheads and internal components, with primarily cosmetic differences.

Key Considerations:
– Mechanical parts are typically interchangeable between same-year models
– Performance characteristics are virtually identical
– Personal preference for styling (Johnson’s white vs. Evinrude’s blue)
– Availability in your local market may determine the best choice

Johnson 115 vs. Modern 4-Stroke Motors

The decision between a vintage two-stroke like the Johnson 115 and a modern four-stroke involves several trade-offs:

Fuel Efficiency: Modern four-strokes are significantly more fuel-efficient, often using 30-50% less fuel at cruising speeds.

Noise & Vibration: Four-stroke engines operate more quietly and with less vibration than two-stroke counterparts.

Weight: The Johnson 115 is relatively lightweight (approx. 320-350 lbs) compared to modern four-strokes of similar horsepower (often 400-500 lbs).

Maintenance Complexity: The simple carbureted design of the Johnson is more owner-serviceable than modern fuel-injected engines with complex computer systems.

Emissions: Modern engines produce significantly fewer emissions, which may be regulated in some areas.

Initial Cost: A used Johnson 115 typically costs a fraction of a new modern outboard.
