  • 5hp outboard motor

  • YAMARINE

5 HP outboard motor is a step up from a 3 HP, offering more power while still being relatively lightweight and portable. It’s a popular choice for small fishing boats, dinghies, and inflatables, providing better speed and handling while remaining fuel-efficient.


Key Features of a 5 HP Outboard Motor

  1. Power & Performance

    • Best for 10-12 ft boats (inflatable, aluminum, or small jon boats).

    • Can push 8-12 mph (depending on boat weight and load).

    • Handles light passengers + gear better than a 3 HP.

  2. Engine Types

    • More fuel-efficient, quieter, no oil mixing needed.

    • Slightly heavier but smoother running.

    • Lighter, simpler, but requires oil-gas mix (e.g., 50:1).

    • Louder and less fuel-efficient than 4-strokes.

    • 2-Stroke

    • 4-Stroke

  3. Weight & Portability

    • Typically 40-60 lbs, still manageable for one person.

    • Most are manual start (pull cord), but some have electric start.

  4. Fuel Efficiency & Tank

    • Burns ~0.3-0.7 gallons per hour.

    • Some have integrated tanks (1-3 gallons), others use external tanks.

  5. Shaft Length

    • Short shaft (15") – Standard for small boats.

    • Long shaft (20") – For deeper transoms (common on inflatables).


Best Uses for a 5 HP Outboard

Small fishing boats (trolling, lake/river use)
Inflatable & dinghy boats (tenders for yachts)
Light jon boats & car-toppers
Backup motor for sailboats

Should You Buy a 5 HP Outboard?

  • Yes, if:

    • You have a small boat (10-12 ft) and need more thrust than 3 HP.

    • You want better fuel efficiency than a 6-10 HP.

    • You prioritize portability & ease of handling.

  • No, if:

    • You have a heavier boat (consider 8-15 HP).
