This comprehensive guide will not only break down the costs but will arm you with the expertise to make a smart, informed purchase that delivers years of reliable service on the water.
Why Consider a 50 HP 2-Stroke? The Undeniable Advantages
Before diving into models and prices, it’s essential to understand why this engine class still commands such a loyal following, even as new production has waned.
Power-to-Weight Ratio: Unmatched Performance
This is the 2-stroke’s crown jewel. By design, a 2-stroke engine fires once per crankshaft revolution (compared to once every two revolutions in a 4-stroke), resulting in a more immediate power pulse. Coupled with a significantly lighter weight—often 50-100 lbs less than a comparable 4-stroke—this translates to exhilarating acceleration and a snappy throttle response. For applications like bass boats or ski boats where getting on plane quickly is paramount, the 50 HP 2-stroke is a legendary performer.
Simplicity & Durability: A Mechanic’s Dream
The 2-stroke engine is elegantly simple. With far fewer moving parts—no complex valve trains, timing belts, or camshafts—there’s simply less to go wrong. This simplicity often translates to remarkable durability and easier, more affordable repairs. For the DIY-minded boater or those in remote areas, the ability to troubleshoot and fix issues with basic tools is a massive advantage. Their robust design is why you still see decades-old 2-strokes running strong today.
The Cost-Effectiveness Argument
While new 2-strokes are scarce, the used market presents a compelling value proposition. You can typically acquire a solid, used 50 HP 2-stroke for significantly less than a newer 4-stroke of equivalent power. This lower entry cost makes it an attractive option for budget-conscious boaters, seasonal users, or as a reliable backup engine.
Deep Dive: The Mercury 50 HP 2-Stroke Legacy
For many, the search for a “50 hp 2 stroke” is synonymous with Mercury. The brand’s classic 2-stroke models, like the “Classic 50” from the 1990s and early 2000s, are icons of reliability.
A Look at Popular Models
Mercury produced several notable 50 HP 2-stroke models. The carbureted “Classic 50” (often in a silver or black finish) is the most common find, prized for its straightforward mechanics. They also produced 50 HP Jet models for shallow-water applications and various “SeaPro” commercial versions. Understanding the specific model and its production era (pre-1990s, 90s-early 2000s) is key to assessing its value and parts availability.
Mercury 50 HP 2-Stroke Price Breakdown: New vs. Used
Finding a brand-new, carbureted 50 HP 2-stroke from a major manufacturer is nearly impossible due to modern emissions regulations. Any “new old stock” would command a premium. Therefore, our focus is the robust used market.
Here’s a realistic price breakdown based on condition:
| Condition / Age | Estimated Price Range | Key Considerations |
|---|---|---|
| Excellent (1-10 yrs old, low hours) | $4,500 – $6,500+ | Likely a direct-injection model (e.g., E-TEC). Well-documented, like-new. |
| Good (5-15 yrs old) | $3,000 – $4,500 | Runs well, may need minor cosmetic touch-ups or standard service (water pump, plugs). |
| Fair (15+ yrs old) | $2,000 – $3,000 | Shows its age. May run but will likely need investment in seals, carb rebuild, or lower unit service. A project candidate. |
Remember: Price is heavily influenced by geography, saltwater history, included controls/prop, and seller motivation. Always budget an extra $500-$1,000 for immediate servicing and rigging.
2-Stroke vs. 4-Stroke: An Honest 2024 Comparison
Choosing between technologies isn’t about good vs. bad; it’s about matching the engine to your specific needs.
Performance & Fuel Efficiency: The Real Story
- 2-Stroke: Delivers superior acceleration and power-to-weight. Historically, they were less fuel-efficient and required mixing oil with gas.
- 4-Stroke: Offers significantly better fuel economy, especially at trolling speeds, and emits fewer pollutants. It’s heavier and can feel less “peppy” off the line but provides smooth, quiet operation.
Modern direct-injection 2-strokes (like Evinrude E-TEC) closed much of the fuel efficiency and emissions gap, but traditional carbureted models remain the simpler, lighter option.
Maintenance & Long-Term Costs
Expert Tip: “Think of maintenance philosophy: a 2-stroke is like a classic motorcycle—it requires consistent, specific care (oil mixing, regular decarb). A 4-stroke is more like your car’s engine—familiar oil changes and valve adjustments. Neglect a 2-stroke, and it fails quickly. Maintain it meticulously, and it will outlast many newer engines.”
While 2-stroke repairs are often cheaper, the potential for higher fuel and oil costs, along with a possibly shorter lifespan under heavy use, must be factored into the total cost of ownership.
Environmental Regulations & Emissions
This is the critical legal factor. Carbureted 2-strokes are banned for new production in most markets due to EPA and EU emissions standards. Always check your local and state regulations regarding the use of older 2-stroke motors, especially on regulated lakes. This is less about performance and more about where you can legally operate the engine.
Expert Buying Guide: What to Look For
Armed with knowledge, here’s how to inspect a used 50 HP 2-stroke like a pro. This is where your due diligence pays off.
5 Critical Inspection Points Before You Buy
- The Compression Test is Non-Negotiable. This is the single best indicator of engine health. All cylinders should be within 10-15% of each other. For a 50 HP 2-stroke, you typically want to see readings of 100+ PSI per cylinder. Low or uneven compression signals worn rings or cylinder damage—walk away.
- Inspect the Lower Unit. Check the gear oil. If it’s milky, water is present, indicating bad seals. Look for obvious damage to the skeg or prop shaft, which can signify impact and internal gear damage.
- Read the Spark Plugs. Their condition tells a story. Chocolate brown is ideal. White or blistered indicates a lean run (dangerous). Oily and fouled points to rich mixture or worn rings.
- Check for Corrosion & Anodes. Pay special attention to the exhaust housing, water passages, and mounting brackets. Ensure the sacrificial anodes (zincs) are not completely eroded, especially if it was used in saltwater.
- Demand a Test Run. It must run under load in a test tank or on the water. Listen for smooth idle, crisp acceleration without hesitation, and a strong stream of water from the tell-tale (pee hole). Watch for excessive smoke.
Hidden Costs You Must Account For
The advertised price is just the start. Budget for:
* Controls & Cables: Often not included. A new set can cost $400-$800.
* Propeller: The existing prop may be damaged or the wrong pitch. A new aluminum prop is $100+, stainless steel $300+.
* Installation & Rigging: If you’re not doing it yourself, professional installation can run $500-$1,500.
* Immediate Service: Assume you’ll need a new water pump impeller kit (~$150 parts & labor), gear oil, spark plugs, and fuel filters for peace of mind.
Frequently Asked Questions (FAQ)
Q: Are 50 HP 2-stroke outboards still being made?
A: Major manufacturers have discontinued production of traditional carbureted 2-strokes due to emissions standards. The last holdouts were advanced direct-injection 2-strokes like Evinrude E-TEC, but that line has also ended. The market is now almost exclusively used.
Q: What is the fuel mix for a Mercury 50 HP 2-stroke?
A: Most Mercury 2-strokes from the 1980s onward use a standard 50:1 fuel-to-oil ratio (one pint of TC-W3 certified outboard oil to six gallons of gasoline). Crucially, always verify this in the owner’s manual for your specific model and year.
Q: Is a 50 HP 2-stroke enough for a pontoon boat?
A: It can be adequate for smaller, lighter pontoons (18-20 feet) used for casual cruising and fishing on calm lakes. However, it may struggle to efficiently plane a loaded pontoon or pull sports equipment. For pontoons, the low-end torque and fuel efficiency of a modern 4-stroke, like the Hidea 50HP 4-Stroke, is often the preferred choice.
Q: What is the lifespan of a well-maintained 50 HP 2-stroke?
A: With meticulous maintenance—proper oil mix, regular use, freshwater flushing after saltwater use, and annual servicing—a quality 2-stroke outboard can deliver 1,500 to 2,000+ hours of reliable service. Neglect, poor fuel, or prolonged disuse are its biggest enemies.
