2017 Honda 15 HP BF15D3SHS Outboard Motor

The 2017 Honda BF15D3SHS is the electric-start version of this short-shaft 15 hp motor, carrying the same listed weight as the otherwise-identical model from the following year, with a 12-amp alternator for stronger charging.

Specifications

Honda's full-throttle number for this engine is 4,500-5,500 rpm, and its gearing covers forward, neutral, and reverse at a 2.08:1 final ratio. Both water cooling and a saltwater rating apply to the block, FC-W 10W-30 oil runs through a wet-sump design, and the four aluminum blades on its 9¼ x 10-inch propeller leave no internal battery to service.

Why electric start here

Choosing electric start over the base manual version mainly matters if you want push-button starting, or if you need the larger charging output this alternator provides for running accessories off the boat's battery. Trim and tilt remain manual on this configuration, worked at the tiller, on a shaft shorter than Honda's other option for this engine family. Two cylinders and 350cc sit behind SOHC valve gear with PGM-IG ignition, fed from a carbureted external tank that holds 3.2 gallons. That's the same basic powerhead used across every short-shaft BF15D3SH variant in this lineup, electric start or not.

Common questions

Does it have power tilt? No, trim and tilt are manual here; only starting is electric.

What propeller comes with it? A four-blade aluminum unit, 9¼ by 10 inches, installed from the factory.
