Secure the ultra-portable, carbureted Mercury 5MH 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 5MH

- Integrated Fuel Tank: Eliminates external gas tanks and heavy fuel lines completely, freeing up critical floor space inside small inflatable tenders.
- 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.
- 360-Degree Tiller Steering: Allows the operator to spin the engine completely around, providing full reverse thrust instantly without a gearbox shifter.
- Optional External Fuel Port: Connects to a standard remote marine tank, extending your cruising range for long days exploring coastal backwaters.
- 25 Kilogram Dry Weight: Maximizes absolute portability, allowing a single operator to lift the engine physically onto high sailboat decks.
- Through-Prop Exhaust: Channels toxic combustion gases directly underwater, keeping the aft operator station completely free of smoke.
- Accessible Oil Drain: Simplifies routine crankcase lubrication changes, saving significant time during seasonal maintenance prep without specialized tools.
- Rugged Gearcase Internals: Transfers single-cylinder horsepower to the propeller securely, maintaining forward momentum on heavily loaded dinghies.
- 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 5MH

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. Rotating the tiller 360 degrees 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.
