Description
Mercury 80ELPT 80HP Jet Outboard Motor
Obstacles and hidden debris in shallow river systems often terminate the journey for propeller-driven outboards. The Mercury 80ELPT Jet Drive provides the ultimate solution by utilizing a high-velocity pump system that enables navigation in inches of water. This 80HP jet-output motor (powered by a high-displacement 2.1L block) provides obstacle-free propulsion and precision remote handling for heavy aluminum river skiffs and jet boats requiring 20-inch transom clearance.
Fully EPA and CARB compliant, this Mercury Jet outboard features Electronic Fuel Injection (EFI) for turn-key starting and superior fuel economy. The integrated Power Trim and Tilt system enables effortless engine tuning for varying load conditions, while the robust pump housing ensures long-term durability in abrasive environments. This engineering approach guarantees sustained thermal stability and component longevity for the most demanding shallow-water professional and recreational applications.

Mercury 80ELPT 80HP Jet Technical Guide
The Mercury 80HP Jet (based on the 2.1L 4-cylinder powerhead) consumes approximately 8.0 to 9.0 gallons per hour at full throttle. Monitoring your gallons per hour rate is vital for jet drives, as efficiency decreases significantly if the intake is obstructed by debris.
This model utilizes Mercury’s MercFusion paint system and high-copper-content aluminum alloys. Regularly inspect the sacrificial aluminum anode locations to prevent galvanic corrosion on the jet pump housing during operation in brackish or salt water.
The 2.1L powerhead requires 5.5 US quarts of oil with a new filter. Adhering to the FC-W engine oil capacity is critical for maintaining engine health, especially since jet applications often require higher sustained RPMs to maintain plane.
The 80HP Jet features a 35-amp alternator to support ignition and standard helm electronics. A battery providing a minimum marine cranking amps rating of 675 MCA is required for consistent starting performance.
This unit utilizes a stainless steel jet impeller instead of a propeller. Maintaining the correct clearance between the impeller and the wear sleeve is essential for maximum thrust and staying within the 5000-6000 RPM window.
