Mercury 105ELPT 105HP – Jet 20″ Shaft Remote Mechanical

Mercury 105ELPT 105HP Jet Drive

The Mercury 105ELPT is a specialized 105HP Jet Drive FourStroke outboard engineered for offshore shallow-water navigation in the United States maritime market. Built upon the legendary 3.0L 150HP base engine architecture and weighing 498 lbs, this powerhouse utilizes a direct jet pump to deliver, unobstructed thrust for rigorous river applications. This 20-inch transom height configuration is designed to completely eliminate lower unit snagging on rocky riverbeds. Our reliable marine outboard solutions is designed to support the mechanical dependability necessary for professional inland marine operations.

Operational peak performance for the Mercury 105 Jet is achieved seamlessly within the 5000 to 5800 RPM full throttle range. The 1.00:1 direct jet drive ratio provides an immense mechanical advantage, translating the 3.0L torque curve into rapid hole-shot acceleration without a vulnerable traditional propeller. Manufactured in the USA, this corrosion-resistant marine engine incorporates advanced vibration dampening to helps support a smooth ride across turbulent whitewater rapids and shallow shoals.

Technical Specifications of Mercury 105ELPT Jet

- The 3.0L inline four-cylinder SOHC architecture delivers displacement for heavy payload hauling capability.
- Direct jet pump propulsion eliminates the traditional lower unit gearcase for offshore shallow water navigation.
- Computer Controlled EFI accurately manages the air-fuel mixture for fuel induction efficiency and immediate throttle response.
- An integrated 60 Amp alternator helps support high-draw onboard marine electronics remain fully charged during long river runs.
- Power Trim and Tilt systems allow rapid engine angle adjustments for optimal hydrodynamic thrust and shallow water clearance.
- SmartCraft compatibility allows engine data integration with modern digital helm displays.

3.0L SOHC Engine Architecture

Derived from the proven 150HP base, this 3.0L 8-valve SOHC design maximizes combustion efficiency while delivering the strong low-end torque needed to drive the high-volume jet pump. This translates into reliable thrust that river guides and shallow-water anglers depend on when navigating fast-moving currents.

Direct Jet Pump Propulsion

The direct jet drive propulsion system utilizes a 1.00:1 ratio to forcefully expel water for forward thrust. This innovative design allows the vessel to safely glide over shallow sandbars, submerged logs, and rocky shoals without risking catastrophic damage to a conventional propeller system.

Computer Controlled EFI

Mercury’s advanced Electronic Fuel Injection continuously monitors atmospheric variables to deliver the appropriate fuel ratio. This is designed to support instant throttle response and prevents engine bogging during rapid acceleration scenarios while navigating tricky channels in unpredictable freshwater environments.

High-Output 60A Alternator

This jet model features a robust 60 Amp alternator that produces net charging power. This helps support high-draw fishfinders, livewell pumps, and bright navigation lights never drain the starting battery during marine days on the river.

Mercury 3-Year Warranty

Every Mercury Jet outboard is backed by a standard 3-Year Limited Warranty for US owners. This factory-level protection helps support long-term peace of mind and grants access to genuine parts through a vast nationwide marine dealer network.

Shallow Water River Match

This remote mechanical jet outboard is a practical power solution for heavy aluminum jet boats and river skiffs. It provides the sustained high-end thrust needed for navigating difficult whitewater rapids while remaining incredibly fuel efficient during long shallow water transits.

Maintenance & Longevity

Regular inspection of the wet sump lubrication system is critical for maintaining the 3.0L engine’s internal tolerances. Always flush the cooling system and jet pump impeller with fresh water after every excursion.Maintenance note: Follow the manufacturer’s service procedures and lubrication specifications for the engine and gearcase.
