2027 Yamaha Four Stroke Portable Fishing-Hunting F8SMHB

Description

Meet the Yamaha F8SMHB in classic Yamaha Gray—an 8 hp four-stroke portable outboard that’s sized just right for small fishing rigs and hunting boats that need dependable push without piling on weight. As an engine-only listing (not a complete boat), this is the kind of standalone power that makes a 15" transom jon boat, utility skiff, or compact tender feel instantly more capable at the ramp and on the water.
With 8 bhp (6 kW) on tap at 5500 RPM, this inline 2-cylinder, 212 cc four-stroke is a strong match for lighter hull classes where clean, steady torque matters more than bragging-rights top speed. The 2.08:1 gear ratio helps turn a propeller with authority, making it easier to get moving with gear aboard and keep a confident pace when you’re cruising between spots. It’s tuned to run in a 5000–6000 full-throttle RPM range, so you can settle into an efficient midrange cruise and let the motor do what it does best: sip regular gas and keep you on plane (or near-plane) depending on your hull and load.
This F8 uses open-loop water cooling and a simple, proven carburetor setup—straightforward, practical, and well suited to owners who want an uncomplicated portable outboard. Starting is pull-start, steering is via a tiller, and trim is manual with four positions, giving you the control to dial in running angle for shallow approaches, varying loads, or changing water conditions.
At 87 lbs dry with a 15-inch shaft, it’s portable enough to move between boats or store when not in use, yet substantial enough to feel planted on the transom. It’s also salt-water capable, and Yamaha adds peace of mind with an engine alert system (visual/audible) plus emergency RPM reduction to help protect the powerhead when conditions demand attention.
If you’re looking for a compact outboard that’s easy to live with, easy on fuel at cruise, and purpose-built for the small-boat fishing-and-hunting lifestyle, the Yamaha Gray F8SMHB is ready to be the dependable muscle on your transom. Warranty coverage varies by dealership/program—contact us and we’ll confirm the current Yamaha warranty details for this new engine.
