Yamaha F2.5SMHB 2.5HP Outboard – 15in Shaft

Description

Ditch the oars and transform your tender experience with the ultra-portable Yamaha F2.5SMHB providing relentless auxiliary power. Weighing a mere 17 kilograms, this 72cc single-cylinder block delivers consistent thrust to maneuver loaded inflatable dinghies against strong tidal currents effortlessly. Verifying your exact transom geometry ensures this 15 inch short shaft portable outboard drops the propeller perfectly into undisturbed water without dragging the gearcase.

Prevent devastating shallow water impacts by utilizing the four-position manual tilt bracket as an immediate physical lifting mechanism. You pivot the engine upward to clear submerged oyster beds and hidden rocks instantly. Yamaha constructs the lower unit using specialized anti-corrosion marine aluminum alloys. This structural barrier stops rapid galvanic decay when repowering small aluminum boats for continuous saltwater use.

Key Features of Yamaha F2.5SMHB

• 72cc Four-Stroke Block: Produces smooth low-end torque internally, pushing heavy square-back canoes steadily against coastal tidal currents.
• 15-Inch Standard Shaft: Matches low dinghy transoms perfectly, preventing lower unit drag and maximizing fuel efficiency on light hulls.
• 360-Degree Tiller Steering: Allows the operator to spin the engine completely around, providing full reverse thrust instantly without a gearbox shifter.
• Integrated 0.9L Fuel Tank: Eliminates external gas tanks and heavy fuel lines, freeing up critical floor space inside small inflatable tenders.
• 17 Kilogram Dry Weight: Maximizes absolute portability, allowing a single operator to lift the engine physically onto high sailboat decks.
• Four-Position Manual Tilt: Adjusts the running angle physically, allowing the operator to lift the gearcase over shallow coastal reefs safely.
• Transistor Controlled Ignition: Fires the spark plug precisely during every rotation, ensuring reliable cold-weather pull starts without a 12-volt battery.
• Splash Lubrication System: Coats internal engine components constantly with oil, preventing thermal breakdown during long continuous harbor transits.
• Above Water Exhaust: Routes combustion gases safely away from the propeller, reducing backpressure to maximize forward pushing power.
• 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 Yamaha F2.5SMHB

Purchasing this 15-inch portable block makes sense strictly for small tenders requiring absolute simplicity. It lacks neutral or reverse gears, relying entirely on physical 360-degree engine rotation. Sourcing a lightweight yamaha portable outboard motor keeps your dinghy legally powered.

• Measure your dinghy transom to confirm a 15-inch vertical drop requirement.
• Ensure the operator possesses the physical strength to lift 17 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 8-12ft aluminum jon boats requiring minimalist eco-friendly power. Because it features a built-in 0.9L fuel tank and weighs just 17 kg, 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 portable outboard motor an incredibly nimble propulsion choice for navigating crowded anchorages.

Warranty, Support and Maintenance

Authorized recreational operation receives a 3-Year Limited Pleasure Craft Warranty. Registered commercial applications fall under a strict 1-Year Commercial 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.
