Yamaha F2.5LMHB 2.5HP Outboard – 20in Shaft

Small sailboats operating as auxiliaries demand the reliable thrust of the Yamaha F2.5LMHB portable outboard to clear crowded harbor basins safely. The compact 72cc carbureted block delivers immediate manual pull starts, pushing loaded displacement hulls efficiently without relying on 12-volt marine batteries. Verifying your exact auxiliary bracket height guarantees this 2.5hp long shaft outboard places the propeller deeply into undisturbed green water.

Navigate safely across shallow flats by utilizing the four-position manual tilt mechanism to lift the gearcase rapidly. You adjust the hull attitude directly from the tiller handle to clear submerged rocky obstacles efficiently. Engineers cast the ultra-light 18 kg lower unit using corrosion-resistant marine alloys. This material barrier stops rapid metal pitting when repowering small inflatable tenders in high-salinity saltwater environments.

Key Features of Yamaha F2.5LMHB

- Manual Recoil Starting: Strips heavy starter motors and battery cables completely from your boat layout, maximizing available gear payload capacity.
- 20-Inch Long Shaft: Reaches deep below elevated sailboat auxiliary brackets, keeping the propeller fully engaged in steep offshore swells.
- 360-Degree Tiller Steering: Allows the operator to spin the engine completely around, providing full reverse thrust instantly without a gearbox shifter.
- 72cc Four-Stroke Powerhead: Produces smooth low-end torque internally, pushing heavy square-back canoes steadily against coastal tidal currents.
- Four-Position Manual Tilt: Features a rigid mechanical lock, safely holding the gearcase out of the water physically while moored at the dock.
- 18 Kilogram Dry Weight: Maximizes absolute portability, allowing a single operator to lift the engine physically onto high sailboat decks.
- Carbureted Fuel Induction: Meters gas reliably into the cylinder, providing steady low-RPM operation when navigating no-wake harbor zones.
- 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.
- 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 F2.5LMHB

You buy this motor to keep rigging dead simple on a tall 20-inch transom boat. It offers zero remote steering capability and lacks heavy electric start components. Finding a reliable manual recoil start outboard solves heavy payload limits on small hulls perfectly.

- Weigh your boat to verify it safely handles this specific 18 kg engine block mass.
- Check the tiller handle sweep path to confirm it clears your rear seating bench.
- Keep local lakes clean by running highly regulated four-stroke engine configurations.

Ideal Application and Vessel Fitment

This ultra-portable 20-inch outboard thrives on small inflatable tenders, sailboat auxiliaries, and rigid fiberglass dinghies requiring minimalist power with maximum payload capacity. Because it strips away heavy electric starter motors and 12-volt battery banks, operators gain absolute ignition reliability for remote area fishing. The direct tiller control provides complete directional thrust, making this lightweight 2.5hp manual start outboard an incredibly nimble propulsion choice for navigating crowded anchorages safely.

Warranty, Support and Maintenance

Authorized recreational operation receives a 3-Year Pleasure Warranty alongside exceptional factory support. 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 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. Mulmotor can assist with product details and order-related questions before purchase.
