Details & Inspection Notes
This 2018-dated BF4DHLHNA is a 4 HP, single-cylinder, 127cc Honda four-stroke on a 20-inch long shaft, tiller steered, with manual pull-start and an external fuel tank. SKU BF4DHLHNA-18.
What this spec covers
Digital CDI fires an OHV head with two valves per cylinder, running on 87-octane unleaded gasoline only, and full throttle on this block tops out at 4500-5500 rpm. The alternator is an optional 6-amp unit that needs separate installation rather than coming built in from the factory, so charging capability is an add-on decision rather than a given.
Before you buy
A 20-inch shaft needs a transom cut for that length; this is the long-shaft listing in this lineup, with a shorter-shaft version sold separately for lower-transom boats. The lower unit is saltwater rated and shifts forward, neutral, and reverse at a 2.08-to-1 ratio, spinning a three-blade aluminum propeller as standard equipment. Oil type is FC-W 10W-30 in a wet-sump system.
What's included
This one ships with the aluminum propeller, an owner's manual, and a tool kit tucked in the box. Dry weight on this one is a listed 60.6000 pounds, and Honda's factory warranty covers it.
Q: Does charging come built in? No, the 6-amp alternator is an optional add-on requiring separate installation.
