Mercury 40HP 40EXLPT SeaPro – CT 25in Shaft

Mercury 40HP 40EXLPT SeaPro CT Extra Long Power

Featuring a 995cc four-cylinder engine family, the Mercury 40HP 40EXLPT SeaPro serves as a high-torque solution for US commercial boaters requiring a prop-rated propulsion unit with superior thermal stability. This 40HP four-stroke technology utilizes a Command Thrust (CT) gearcase and a larger propeller footprint to maximize mechanical efficiency on ultra-high transom vessels and commercial barges. The 25-inch extra-long shaft design provides an optimized center of gravity for deeper draft hulls, while the Electronic Fuel Injection (EFI) and remote configuration ensure immediate, reliable ignition across diverse inland and coastal environments.

Operational longevity of the 40EXLPT model is secured through a specialized pressurized lubrication system featuring a maintenance-free valve train to maintain internal cleanliness. To facilitate easy after-storage starts, the unit employs a sophisticated EFI system paired with an 18A high-output alternator for accessory maintenance, while the Mercury XK360 alloy science utilizes a multi-layer finish to mitigate oxidation. With a commercial-specific warranty and oversized gearcase, this fuel-efficient outboard provides superior ownership value for professionals seeking high-thrust performance and durability in specialized transom heights.
