Twin 2006 Yamaha 250 Hp 4-Stroke 25″ Outboard Motors for Sale

The Twin 2006 Yamaha 250 HP 4-Stroke 25″ Outboard Motors are built for serious boat owners who demand power, endurance, and long-term value from their marine engines. Designed for both offshore and inshore performance, these V6 four-stroke units deliver a rare balance of smooth power delivery, fuel efficiency, and mechanical reliability that continues to make Yamaha’s 250 HP series a preferred choice among professional boaters and recreational captains alike.

These twin motors are expertly reconditioned and fully inspected, ensuring dependable performance from the first ignition. Perfect for repowering mid-to-large-size boats, they provide the thrust and torque needed for demanding marine applications—whether it’s long-range cruising, offshore fishing, or commercial utility use.

Power & Engineering Excellence

At the core of each engine lies Yamaha’s 3.3-liter V6 DOHC 16-valve powerhead. This proven design delivers up to 250 horsepower at 5,500 RPM, giving your vessel strong mid-range torque and responsive acceleration. Yamaha’s electronic fuel injection (EFI) system precisely meters fuel for optimal combustion, resulting in better throttle response, cleaner emissions, and lower fuel consumption compared with older carbureted designs.

The 25-inch shaft length (extra-long) offers exceptional versatility for offshore hulls and deeper transoms, maintaining consistent propeller bite and stability even in rough conditions. Combined with Yamaha’s corrosion-resistant materials and multi-layer marine coatings, these motors are engineered to withstand long exposure to saltwater environments.

Performance & Benefits

The twin setup delivers balanced propulsion and increased redundancy, a critical advantage for offshore anglers and long-range cruisers who require confidence in their power system. Each 250 HP outboard provides smooth, quiet operation and minimal vibration, thanks to Yamaha’s advanced counter-balancing and exhaust design.

Key performance advantages include:

• Exceptional Fuel Efficiency: Four-stroke EFI technology provides a leaner burn and reduced fuel costs.

• High Output Charging System: Reliable alternator power supports onboard electronics and navigation gear.

• Precision Shift & Throttle Control: Responsive handling at all speeds, ideal for docking or trolling.

• Proven Reliability: Built on Yamaha’s heritage of marine engineering excellence, these engines routinely exceed 2,000 hours with proper maintenance.

Safety & Responsible Operation

Safety is integral to Yamaha design. The 2006 Yamaha 250 HP four-stroke series features automatic over-rev protection, overheat sensors, and low-oil alerts. Operators are encouraged to follow Yamaha’s recommended safety practices—always use appropriate engine guards, maintain proper ventilation in enclosed spaces, and ensure all electrical connections remain dry and corrosion-free.

Longevity & Maintenance Tips

Proper maintenance dramatically extends engine life. Routine oil changes every 100 hours, fuel filter replacement, and flushing the cooling system after saltwater use are key to longevity. Inspect propeller shafts, anodes, and seals periodically, and store motors vertically in a dry, covered area during the off-season.

Before winterization, stabilize the fuel system and fog the cylinders to prevent corrosion. Yamaha-approved lubricants and parts are strongly recommended to preserve performance and warranty integrity.
