Mercury 5MLHA 5HP Outboard – 20in Shaft, Tiller, Charging

Description

Mount the alternator-equipped, long-shaft Mercury 5MLHA to eliminate dead house batteries on small cruising sailboats. The 123cc single-cylinder block spins a specialized high-thrust propeller, pushing heavy displacement hulls steadily against steep morning tides. Taping your auxiliary bracket confirms this 20 inch long shaft portable outboard reaches undisturbed green water safely.

Replenish drained electrical systems actively while motor-sailing by leveraging the integrated 12V 4A charging circuit as a dedicated onboard generator. You route the factory wiring directly to your battery bank for automatic voltage recovery. Mercury engineers the water-cooled 27 kg block using multi-stage marine primers. This physical barrier blocks cosmetic paint blistering when repowering small sailboats in harsh saltwater environments.

Key Features of Mercury 5MLHA

• Integrated 4-Amp Alternator: Outputs 50 watts of constant electrical current underway, powering essential navigation lights and recharging small 12-volt sailboat batteries.
• 20-Inch Long Shaft: Reaches deep below elevated sailboat auxiliary brackets, keeping the propeller fully engaged during steep coastal swells.
• High-Thrust Sail Propeller: Bites into the water aggressively at low speeds, providing massive stopping power and reverse control for heavy vessels.
• 360-Degree Tiller Steering: Allows the captain to spin the block backward completely, providing direct reverse thrust for backing into slips.
• Six-Position Manual Tilt: Lifts the gearcase physically above the waterline, preventing damaging marine algae growth while the sailboat is moored.
• Multi-Stage Marine Primer: Bonds chemically to the alloy block, reflecting harsh ultraviolet light and preventing cosmetic saltwater blistering over time.
• Through-Prop Exhaust Routing: Forces combustion gases directly underwater, significantly reducing engine noise and raw fumes at the operator seating position.
• Accessible Oil Drain: Simplifies routine crankcase lubrication changes, saving significant time during seasonal maintenance prep without specialized tools.
• Rugged Lower Unit: Transfers single-cylinder horsepower to the propeller securely, maintaining forward momentum on heavily loaded displacement hulls.
• Clean Four-Stroke Combustion: Burns unleaded fuel highly efficiently without messy two-stroke oil mixing, keeping pristine anchorages completely free of surface oil slicks.

Why Choose Mercury 5MLHA

This specific 20-inch Sail Power block is built strictly to serve as auxiliary sailboat propulsion with battery charging needs. Mounting it on a standard 15-inch dinghy will cause massive lower unit drag. Installing a reliable long shaft portable outboard motor ensures safe harbor returns.

• Verify your sailboat motor bracket requires exactly a 20-inch vertical shaft drop.
• Connect the factory charging circuit securely to your onboard 12-volt battery system.
• Avoid toxic exhaust fumes using advanced four-stroke internal lubrication.

Ideal Application and Vessel Fitment

This 20-inch long-shaft Sail Power configuration is engineered specifically as a primary kicker for small sailboats and auxiliary power for high-transom displacement hulls demanding onboard electrical generation. The extended midsection ensures the specialized high-thrust propeller remains deeply submerged when the vessel pitches in steep ocean swells. By utilizing a 4-amp alternator and 360-degree steering, captains gain total directional control while charging electronics, making this long shaft portable outboard motor an essential tool for maneuvering heavy sailboats safely through crowded coastal marinas.

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. Mulmotor provides product-information support before purchase and assistance with order-related questions.
