Mercury 4MH 4HP Outboard – 15in Shaft, Tiller, Manual Start

Description

Secure the ultra-portable, carbureted Mercury 4MH to eliminate exhaustive rowing on small displacement hunting skiffs. Weighing just 25 kg, this 123cc single-cylinder block forces steady forward thrust, pushing loaded inflatable tenders across choppy marina basins. Measuring your mounting bracket verifies this 15 inch short shaft portable outboard operates without excessive drag.

Navigate safely across shallow flats by utilizing the six-position manual tilt mechanism to lift the gearcase rapidly. You adjust the hull attitude directly from the tiller handle to clear submerged obstacles. Mercury casts the lower unit using corrosion-resistant aluminum alloys. This material barrier stops rapid metal pitting when leaving the kicker motor clamped to saltwater transoms.

Key Features of Mercury 4MH

• 25 Kilogram Dry Weight: Maximizes absolute portability, allowing a single operator to lift the engine physically onto high sailboat decks.
• 15-Inch Standard Shaft: Matches low dinghy transoms perfectly, preventing lower unit drag and maximizing fuel efficiency on light hulls.
• Six-Position Manual Tilt: Adjusts the running angle physically, allowing the operator to lift the gearcase over shallow coastal reefs safely.
• Integrated Fuel Tank: Eliminates external gas tanks and heavy fuel lines, freeing up critical floor space inside small inflatable tenders.
• 123cc Four-Stroke Powerhead: Produces smooth low-end torque internally, pushing heavy square-back canoes steadily against coastal tidal currents.
• Multi-Function Tiller Handle: Concentrates shift and throttle inputs squarely in your grip, sharpening handling response in narrow twisting creeks.
• Carbureted Fuel Induction: Meters gas reliably into the cylinder, providing steady low-RPM operation when navigating no-wake harbor zones.
• Manual Recoil Starter: Engages the flywheel directly via a physical pull cord, guaranteeing reliable ignition without heavy 12-volt battery systems.
• Corrosion-Resistant Castings: Blocks severe galvanic decay physically, protecting the powerhead block across decades of daily saltwater exposure.
• Clean Four-Stroke Combustion: Burns unleaded fuel highly efficiently without messy two-stroke oil mixing, keeping your tender completely free of oil slicks.

Why Choose Mercury 4MH

You purchase this 15-inch portable block strictly for small tenders or square-back canoes requiring absolute simplicity. It lacks remote steering and relies entirely on physical tiller operation. Sourcing a lightweight mercury portable outboard motor keeps your tender legally powered.

• Measure your dinghy transom to confirm a 15-inch vertical drop requirement.
• Ensure the operator possesses the physical strength to lift 25 kilograms safely.
• Comply with strict harbor emissions laws utilizing clean-burning four-stroke technology.

Ideal Application and Vessel Fitment

This ultra-portable 15-inch outboard thrives on small inflatable tenders, square-back canoes, and rigid fiberglass dinghies requiring minimalist power. Because it features an integral fuel tank and weighs just 25 kilograms, operators can easily physically carry it from the main deck down to the tender. The direct tiller control provides complete directional thrust, making this lightweight mercury portable outboard motor an incredibly nimble propulsion choice for navigating crowded anchorages and tight marina fairways.

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 replacing gearcase lubricants and checking spark plugs 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. For product details and order support, Mulmotor offers assistance before your purchase is placed.
