Description
Rig the electric-start, long-shaft Mercury 8ELH to eradicate water pump starvation on tall sailboat transoms. The 208cc inline-two block forces immediate low-end torque, pushing heavily loaded displacement hulls steadily against morning tidal currents. Measuring your auxiliary bracket confirms this 20 inch long shaft tiller outboard operates safely without sucking surface air in heavy chop.
Clear underwater debris safely in shallow creeks by utilizing the manual tilt bracket as a direct physical lifting aid. You simply grab the rear cowl grip to pull the 39 kg gearcase upward instantly. Mercury engineers the water-cooled block using multi-stage marine primers. This physical barrier blocks cosmetic paint blistering when repowering high-transom sailboats in harsh saltwater environments.
Key Features of Mercury 8ELH
- Turn-Key Electric Start: Engages the flywheel instantly via 12-volt battery power, eliminating shoulder strain completely during freezing early morning launches.
- 20-Inch Long Shaft: Reaches deep below elevated sailboat auxiliary brackets, keeping the propeller fully engaged during steep coastal swells.
- Multi-Function Tiller Handle: Concentrates shift and throttle inputs squarely in your grip, sharpening handling response in narrow twisting creeks.
- 6-Amp Charging Alternator: Outputs constant electrical current while running, keeping small deep cycle batteries topped off for navigation lights.
- 208cc Inline-Two Block: Produces smooth low-end torque internally, pushing heavy displacement hulls steadily against coastal tidal currents.
- Manual Tilt Bracket: Features a rigid mechanical lock, safely holding the gearcase out of the water physically while moored at the dock.
- 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.
- 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 8ELH
This specific build fits only 20-inch transoms requiring direct physical tiller control. The extended shaft creates massive drag if mounted on a standard 15-inch boat. You cannot wire this to a forward console steering wheel. Procuring an electric start long shaft outboard secures heavy-duty off-grid reliability.
- Confirm a 20-inch vertical measurement from the transom top to the keel.
- Verify the tiller handle sweep path clears your rear bench seating completely.
- Avoid toxic exhaust fumes using advanced four-stroke internal lubrication.
Ideal Application and Vessel Fitment
This 20-inch electric-start tiller engine is engineered specifically for tall-transom aluminum work skiffs, sailboat auxiliaries, and commercial river-running hulls demanding extra reach. By integrating push-button ignition, operators gain maximum convenience while navigating treacherous currents. The specialized extra-long midsection guarantees this 8 hp long shaft tiller outboard maintains propeller bite in steep ocean swells, making it the ultimate auxiliary power plant for rugged coastal exploration far beyond standard marina services.
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 changing 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. For product details and order support, Mulmotor offers assistance before your purchase is placed.
