Mercury 115HP F115 4-Stroke Long Shaft Outboard Motor L PRO XS Key Features

• Engine Type: Inline 4-cylinder, 8-valve single overhead cam (SOHC) four-stroke engine.
• Horsepower: 115 hp.
• Displacement: 2.1 Liters, the highest displacement in its class, which contributes to more torque and better performance.
• Weight: It is the lightest engine in its class, with a dry weight of approximately 359 lbs (163 kg).
• Shaft Length: It is available in a 25" (635 mm) "long shaft" configuration (designated by the 'L' in the model name).
• Performance: Features performance tuning for a higher wide-open-throttle (WOT) rpm range (5300-6300 RPM) to achieve faster top speeds and quicker hole shots than standard 115hp engines.
• Fuel System: Computer-controlled multi-port electronic fuel injection (EFI) for optimal fuel efficiency and power.
• Charging System: Equipped with "Idle Charge" technology, which automatically increases idle rpm to boost alternator output and recharge low batteries, supporting power demands of modern marine electronics.
• Gearcase Options: Available with the standard gearcase or the "Command Thrust" (CT) gearcase option, which features a larger torpedo and prop for more leverage and better handling of heavier boats.
• Durability: Engineered with Mercury's ultra-low copper content alloys for superior corrosion protection, suitable for both fresh and saltwater use.
• SmartCraft Compatible: Fully compatible with Mercury's SmartCraft digital technology for engine monitoring and diagnostics.

Mercury 115HP F115 4-Stroke Long Shaft Outboard Motor L PRO XS FAQs

• What is the primary difference between the 115 Pro XS  and the standard 115 HP FourStroke? The main difference is performance tuning, allowing the 
  Pro XS  to operate at a higher RPM (up to 6,300) compared to the standard model (6,000) for enhanced speed and quicker acceleration.
• Is the Pro XS  version faster than the standard model? Yes, the 115 HP Pro XS can achieve a higher top speed and faster acceleration, reducing 0-20 mph acceleration time by 1 to 2 seconds compared to the standard 115 HP Four Stroke.
• How does it achieve better performance? It utilizes a high-displacement 2.1L powerhead and includes Transient Spark technology for improved torque during acceleration. It can also effectively use lower-pitch propellers.
• What is the "Idle Charge" feature? Idle Charge technology increases idle RPM to boost alternator output and recharge low batteries, providing more battery charging at idle speed.
• What is the shaft length of the "L" model? The "L" indicates a 20-inch shaft length, while an "XL" model offers a 25-inch shaft.
• What type of gearcase does it use? It is available with a standard gearcase or an optional Command Thrust (CT) gearcase designed for heavier boats.
• What is the recommended fuel and oil? The recommended fuel is Unleaded 90RON minimum, and the recommended oil is Mercury Four Stroke Oil 10W-30.
• What is the oil capacity? The oil capacity is approximately  5.2 litres
