Mercury 25ELHGA 25HP Outboard – 15in, Jet Drive, Tiller

Description

Mount the shallow-water, jet-driven Mercury 25ELHGA to navigate rocky riverbeds that destroy standard propellers. Utilizing a massive 526cc powerhead, this EFI block forces high-pressure water directly through the pump volute, yielding 25 horsepower of pure jet thrust. Verifying your hull geometry confirms this mercury 25hp jet drive outboard mounts correctly to a 20-inch tall jet-specific transom.

Struggling to lift a heavy engine block in sudden shallows? The integrated gas-assist tilt cylinder acts as a mechanical lifting aid. You pop the tiller release and the 84 kg engine springs upward instantly. Engineers cast the jet pump housing from heavy-duty impact alloys. This structural barrier survives direct gravel bar impacts when repowering aluminum river boats for extreme backcountry access.

Key Features of Mercury 25ELHGA

• Direct Drive Jet Pump: Eliminates the vulnerable lower unit gearcase and propeller entirely, allowing safe navigation over shallow rocky riverbeds without catastrophic drivetrain damage.
• 526cc Powerhead Block: Generates 40 horsepower internally to offset jet pump parasitic loss, delivering a true 25 horsepower of thrust at the nozzle.
• Gas-Assist Tilt Cylinder: Uses pressurized gas struts to offset the heavy 84 kg block weight, allowing the operator to lift the engine effortlessly with one hand.
• 15-Inch Jet Configuration: Mounts specifically to tall 20-inch boat transoms, placing the jet water intake perfectly flush with the flat hull bottom.
• Electric Push-Button Start: Engages the flywheel instantly via 12-volt battery power, eliminating shoulder strain completely during freezing early morning river launches.
• Multi-Function Tiller Handle: Concentrates shift, throttle, and steering inputs squarely in your grip, sharpening handling response in narrow twisting creeks.
• 15-Amp Alternator System: Outputs constant electrical current underway, powering essential navigation lights and bilge pumps reliably against strong river currents.
• Stainless Steel Impeller: Withstands aggressive abrasion from sand and gravel intake, maintaining tight pump tolerances for maximum thrust efficiency.
• Electronic Fuel Injection: Atomizes gas instantly at 5000 RPM, eliminating carburetor jet clogging and ensuring crisp throttle translation on lightweight aluminum hulls.
• Clean Four-Stroke Combustion: Burns fuel highly efficiently without oil mixing, easily meeting strict local waterway emissions regulations and EPA standards.

Why Choose Mercury 25ELHGA

You select this specialized jet outboard strictly to run extreme shallow water rivers. It demands a flat-bottom hull with a 20-inch transom height to align the jet intake properly. Mounting this on a deep-V hull will suck air instantly. Securing a shallow water jet outboard prevents catastrophic lower unit destruction.

• Ensure your flat-bottom aluminum hull features a strict 20-inch jet-cut transom.
• Verify operator ability to utilize the gas-assist cylinder to clear underwater gravel bars quickly.
• Meet strict lake emission standards via certified low-emission combustion processes.

Ideal Application and Vessel Fitment

This specialized jet outboard is built exclusively for flat-bottom aluminum river sleds, shallow-draft jon boats, and specialized skinny-water hunting skiffs. Because the direct-drive jet pump sits flush with the hull bottom, it completely eliminates the draft penalties of a standard propeller, allowing operators to run on plane across mere inches of water. It thrives in treacherous, rock-strewn rivers and shallow tidal flats where traditional gearcases would instantly shatter, delivering unmatched backcountry access for extreme hunters and river anglers.

Warranty, Support and Maintenance

Authorized recreational operation receives a 3-Year Limited Warranty alongside a 3-Year Corrosion Warranty. Registered commercial applications fall under a strict 1-Year Limited Warranty with zero corrosion coverage applied to the block. Scheduled maintenance requires greasing jet pump bearings and changing powerhead oil filters at manual-specified intervals. Always save all physical service records. Your engine serial number acts as the only way to source exact genuine replacement parts. Mulmotor provides product-information support before purchase and assistance with order-related questions.
