2017 Honda 15 HP BF15D3SH Outboard Motor

The 2017 Honda BF15D3SH is a short-shaft, 15 hp portable outboard with tiller steering and manual starting, carrying the same listed weight as the short-shaft electric-start model in this family.

Specifications

Honda's rating for full throttle on this engine is 4,500-5,500 rpm, with the gearcase stepping through forward, neutral, and reverse on a 2.08:1 final ratio. Cooling draws fresh water through a block that Honda rates for saltwater as well, and a 6-amp alternator keeps the battery charged while running. Oil is FC-W 10W-30 in a wet-sump lubrication setup, and propeller size here is 9¼ x 10 inches with four aluminum blades, fitted at the factory; there's no internal battery to service.

Why the 15-inch shaft

Honda offers this 350cc, two-cylinder engine on two different shaft lengths, and this particular listing is the shorter 15-inch one, suited to a lower-transom boat rather than a tall one. Everything is worked by hand here: tiller steering, manual trim and tilt, and a pull-cord starter. Valve operation is SOHC, ignition is PGM-IG, each cylinder carries two valves, and an externally mounted 3.2-gallon tank feeds the carburetor. None of that changes depending on which shaft length you pick; only the mounting height and the control layout differ between the two.

Common questions

Does this have electric start? No, starting is manual only, by pull cord.

How long is Honda's coverage? 5 years from the factory.
