Mercury 25EXLPT 25HP – ProKicker EFI 25″ Shaft Remote Mechanical

Mercury 25EXLPT 25HP ProKicker EFI

The Mercury 25EXLPT ProKicker is a practical 25HP FourStroke outboard engineered for high-thrust auxiliary propulsion and remote steering integration on high-transom vessels in the US maritime market. Utilizing a robust 500cc twin-cylinder SOHC architecture and weighing 168 lbs, This engine features an strong gearcase to deliver unparalleled low-speed torque. This 25-inch extra-long shaft model is configured with a remote mechanical helm control and integrated Power Trim & Tilt, making it the premier kicker motor for large offshore sailboats and heavy fiberglass transoms. Our dependable outboard propulsion systems provide the precision necessary for professional marine navigation.

Peak operational performance for this Mercury 25HP ProKicker occurs between 5400 and 5800 RPM, utilizing a sophisticated Electronic Fuel Injection system for low-speed thermal efficiency. The specialized high-thrust 2.15:1 gear ratio provides rapid hole-shot and superior heavy-load boat control in rough coastal conditions. Built with premium US-engineered quality, this corrosion-resistant unit includes exclusive vibration dampening mounts for an exceptionally quiet experience during long offshore motor-sailing or trolling sessions.

Technical Specifications of Mercury 25EXLPT ProKicker

- High-displacement 500cc twin-cylinder engine architecture delivers torque for auxiliary pushing power.
- The 25-inch extra-long shaft provides deep propeller immersion for high-transom offshore and commercial auxiliary applications.
- Remote mechanical steering compatibility allows tie-bar integration with the vessel’s primary outboard steering system.
- Electronic Fuel Injection (EFI) helps support reliable firing, zero-choke starting, and incredibly low fuel consumption at trolling speeds.
- A 15 Amp high-output alternator delivers reliable charging power to keep navigation systems and vessel electronics running.
- Integrated Power Trim & Tilt system allows the operator to effectively adjust the engine angle from the helm for rapid deployment.

ProKicker High Thrust Engineering

The defining feature of the ProKicker series is its engineered focus on low-speed thrust. By pairing the 2.15:1 gear ratio with a high-thrust lower unit, it minimizes slip and maximizes bite. This makes it a practical kicker solution for heavy displacement sailboats navigating strong coastal currents and offshore winds.

Extra-Long 25-Inch Shaft

The 25-inch extra-long shaft is purposefully designed for sailboat auxiliary brackets and offshore high-transom applications. Its hydrodynamic profile minimizes drag while ensuring the propeller stays deeply submerged for consistent forward thrust, effectively preventing cavitation in large rolling ocean swells.

SmartCraft Digital Integration

Equipped with SmartCraft compatibility, this 25HP ProKicker allows captains to monitor real-time engine health, fuel flow, and RPM data. This level of digital integration is vital for offshore sailors who need to maintain precise fuel management during long transits in the American saltwater environment.

Mercury 3-Year Protection

Mercury Marine protects this 25HP ProKicker unit with a comprehensive 3-Year Limited Warranty for American boat owners. This factory-backed coverage covers structural and mechanical defects to helps support long-term maritime reliability.

Heavy-Duty Auxiliary Match

This remote 25-inch ProKicker outboard is the premier auxiliary match for large sailboats, heavy displacement hulls, and offshore aluminum rigs. It provides the sustained low-end thrust needed for precise boat positioning while remaining incredibly fuel-efficient.

Maintenance & Longevity

Routine maintenance of the wet sump lubrication system is vital for preserving internal mechanical tolerances during extended low-RPM use. Always flush the cooling system with fresh water after each salt-water mission.Maintenance note: Follow the manufacturer’s service procedures and lubrication specifications for the engine and gearcase.
