Honda 20HP Portable Outboard | BF20D3SH

At 103 pounds, this Honda BF20D3SH is the lightest build in this group of 20 hp listings, carrying a 15-inch short shaft, tiller steering, and manual start rather than the longer shaft or added electrics found elsewhere in Honda's lineup. The 350cc, two-cylinder engine is carbureted, its rev range topping out near 6000 rpm once full throttle opens around 5000.

What to check before buying

Fifteen inches is the short-shaft option, meant for a lower transom than a long-shaft 20 hp motor would need; measure before ordering rather than assuming it fits a taller hull. With manual start and tiller steering, there's no battery or remote console to wire in anywhere on this build.

What comes with it

The motor arrives with a propeller, a charging circuit, an outside tank good for 3 gallons feeding through its own line, and a lanyard-style stop switch, topped off with the printed manual.

Keeping it running

A motor this small is easy to store off-season: run the tank down or add stabilizer before putting it away, since a gummed-up carburetor from stale fuel is the most common complaint on small portable outboards left sitting over winter.

Is a battery needed to start this motor? No, starting is by manual pull cord. What's the shaft length? 15 inches, the short option here. Does it have shallow water drive? Yes.
