Mercury 3.5MLH 3.5HP – Four Stroke Manual Tiller 20-Inch

Mercury 3.5MLH 3.5HP Portable Outboard

The Mercury 3.5MLH is an ultra-lightweight 3.5HP FourStroke outboard engineered for maximum portability and manual tiller control on high-transom vessels in the US recreational boating sector. Boasting a compact 85cc single-cylinder OHV engine architecture and a dry weight of just 41 lbs, it offers a superior power-to-weight ratio for small sailboats and high-transom square-stern canoes. Our reliable marine outboard solutions deliver the mechanical simplicity and 20-inch shaft length required for consistent thrust on specialized portable craft.

Operational peak performance for this Mercury 3.5HP is achieved between 5000 and 6000 RPM. The 2.15:1 gear ratio provides a distinct mechanical advantage, translating the OHV torque into steady propulsion for displacement hulls. Manufactured in the USA, this corrosion-resistant motor features a unique 360-degree pivot steering system and CDI ignition with Electronic Spark Advance to helps support reliable starting and quiet operation during peaceful coastal exploration.

Technical Specifications of Mercury 3.5MH

- Ultra-lightweight 41 lbs dry weight makes it exceptionally easy to transport and mount on high-transom brackets.
- 360-degree pivot steering provides full thrust in any direction, eliminating the need for a heavy mechanical reverse gear.
- Simple 2-valve pushrod carbureted induction helps support straightforward mechanical operation and easy field maintenance.
- Manual 4-position trim system allows for precise engine angling to navigate shallow water and rocky shorelines safely.
- 20-inch long shaft length is purposefully designed for sailboat auxiliary mounts and high-transom utility skiffs.
- Integrated splash lubrication system helps support the internal 85cc engine components remain protected during all-day use.

Ultra-Portable 41 Lbs Architecture

At only 41 lbs, the Mercury 3.5MLH is designed for the solo adventurer requiring a long-shaft motor. It can be easily transported in a vehicle or carried to remote launch sites, making it a practical power solution for high-transom portable vessels like inflatables and sailboats in the American wilderness.

360-Degree Steering Versatility

The innovative 360-degree steering system allows for total maneuverability. By pivoting the engine 180 degrees, the captain can achieve full reverse thrust without the complexity of a mechanical gear shift. This design reduces internal weight and improves overall durability for small boat explorers.

Long Shaft Auxiliary Match

The 20-inch long shaft is the defining feature of this model, designed to reach deeper water from high-transom mounting points. This prevents propeller ventilation in choppy conditions, making it an ideal choice for sailboat auxiliary power where standard short-shaft motors would lose hydrodynamic grip.

Mercury 3-Year Protection

Every portable Mercury 3.5HP unit is backed by a comprehensive 3-Year Limited Warranty for American owners. This factory-level protection helps support long-term peace of mind and grants access to genuine parts through a vast nationwide marine dealer service network.

Maintenance & Longevity

Maintaining the 0.3L oil capacity in the splash lubrication system is vital for preserving the engine’s tight mechanical tolerances. Always flush the cooling passages with fresh water after each use.Maintenance note: Follow the manufacturer’s service procedures and lubrication specifications for the engine and gearcase.
