8hp outboard motor
YAMARINE
8 HP outboard motor is a versatile mid-range engine, offering significantly more power than a 5 HP while still being relatively lightweight. It’s ideal for 12-14 ft boats, including fishing boats, inflatables, and small aluminum hulls, providing better speed and load capacity without being overly heavy.
Best for 12-16 ft boats (jon boats, inflatables, small skiffs).
Speed: ~12-18 mph (depends on boat weight & load).
Handles 2-3 adults + gear much better than a 5 HP.
2-Stroke (older models)
Lighter (~50-65 lbs) and simpler, but requires oil-gas mix.
More power per weight, but louder and less fuel-efficient.
4-Stroke (modern standard)
Heavier (~70-90 lbs), but smoother, quieter, and more fuel-efficient.
No oil mixing needed, better for trolling.
4-Stroke: ~75-90 lbs (some models are lighter, like the Tohatsu 8 HP at 83 lbs).
2-Stroke: ~50-65 lbs (easier to carry, but harder to find new).
Most are manual start, but some high-end models offer electric start.
External fuel tank (usually 3-6 gallons).
Fuel consumption: ~0.5-1.2 gallons per hour at full throttle.
Short (15") – Standard for small boats.
Long (20") – Better for inflatables or deeper transoms.
✔ Fishing boats (better for trolling than 5 HP).
✔ Inflatable dinghies & tenders (for yachts/sailboats).
✔ Small aluminum jon boats & car-toppers.
✔ Backup motor for larger boats.
| Brand/Model | Type | Weight | Key Features |
|---|---|---|---|
| Tohatsu MFS8 | 4-Stroke | 83 lbs | Lightest 4-stroke, same as Mercury/Nissan |
| Mercury 8 HP | 4-Stroke | 83 lbs | Reliable, rebranded Tohatsu |
| Yamaha 8 HP | 4-Stroke | 87 lbs | Strong mid-range, good for saltwater |
| Honda BF8 | 4-Stroke | 90 lbs | Ultra-smooth, very quiet |
| Suzuki DF9.9 (similar class) | 4-Stroke | 97 lbs | More power, slightly heavier |
(Note: Many brands skip 8 HP and go straight to 9.9 HP, which is nearly the same weight but more power.)
✅ Pros:
More thrust & speed than 5 HP, better for heavier loads.
Still manageable weight for one person (unlike 15+ HP).
Good fuel efficiency for its power class.
Can plane a small boat (unlike 3-5 HP).
❌ Cons:
Heavier than 5 HP (harder to carry).
No power trim/tilt (manual only).
Not enough for rough waters or heavy boats.
Yes, if:
You have a 12-14 ft boat and need more power than 5 HP.
You want better speed without going too heavy (like 9.9-15 HP).
You troll frequently (4-stroke is ideal).
No, if:
You have a heavy boat (consider 9.9-15 HP).
You need electric start & power tilt (look at 15+ HP).
New (~$2,500-$3,500): Fuel-efficient, low emissions, warranty.
Used ($800-$2,000): Older 2-strokes are lighter but less efficient.
Many boaters prefer a 9.9 HP because:
Often the same weight as 8 HP.
More power for nearly the same price
