Mercury 15EXLPT ProKicker 15HP – Four Stroke 25-Inch

Mercury 15EXLPT 15HP ProKicker Remote

The Mercury 15EXLPT ProKicker is an elite 15HP FourStroke outboard engineered for high-thrust auxiliary propulsion and seamless remote steering integration on high-transom vessels in the US marine market. Utilizing a robust 333cc twin-cylinder SOHC architecture and weighing 122 lbs, this specialized engine delivers an incredibly aggressive torque curve for heavy displacement vessels. This 25-inch extra-long shaft model is configured with a remote mechanical helm control and integrated Power Tilt, making it the ultimate kicker motor for large offshore sailboats and deep-V fiberglass hulls. Our dependable outboard propulsion systems provide the precision necessary for professional offshore navigation.

Peak operational performance for this Mercury 15HP ProKicker occurs between 5700 and 6200 RPM, utilizing a sophisticated Electronic Fuel Injection system for unmatched 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 motor-sailing or trolling sessions.

Technical Specifications of Mercury 15EXLPT ProKicker

• High-displacement 333cc twin-cylinder engine architecture delivers massive torque for unmatched auxiliary pushing power.
• The 25-inch extra-long shaft provides deep propeller immersion for high-transom offshore and commercial applications.
• Remote mechanical steering compatibility allows seamless tie-bar integration with the vessel’s primary outboard steering system.
• Electronic Fuel Injection (EFI) ensures reliable firing, zero-choke starting, and incredibly low fuel consumption at trolling speeds.
• A 12 Amp high-output alternator delivers reliable charging power to keep navigation systems and vessel electronics running.
• Integrated Power 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 the ultimate kicker solution for heavy displacement sailboats navigating strong coastal currents and offshore winds.

Remote Helm Integration

Designed for multi-engine setups, this remote-controlled kicker can be easily linked to the main outboard via a steering tie-bar. This allows captains to steer the kicker motor directly from the primary helm station, offering unparalleled convenience and safety during rough-water trolling scenarios.

Extra-Long 25-Inch Shaft

The 25-inch extra-long shaft is purposefully designed for sailboat auxiliary brackets and extreme 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.

Mercury 3-Year Protection

Mercury Marine protects this 15HP ProKicker unit with a comprehensive 3-Year Limited Warranty for American boat owners. This factory-backed coverage covers structural and mechanical defects to ensure long-term maritime reliability.

Heavy-Duty Auxiliary Match

This remote 25-inch ProKicker outboard is the absolute 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 1.0L oil capacity and wet sump lubrication system is vital for maintaining internal mechanical tolerances during extended low-RPM use. Always flush the cooling system with fresh water after each salt-water mission. Pro Tip from the Shop: Because remote kickers are often steered via a tie-bar, frequently inspect and grease the steering linkage and remote shift cables to prevent binding caused by constant exposure to corrosive saltwater spray.
