15FMH outboard motor
YAMARINE
15 HP outboard motor is a powerful yet compact engine, ideal for 14-18 ft boats, including fishing boats, small pontoons, and aluminum utility boats. It offers a great balance between power, weight, and fuel efficiency, making it one of the most versatile outboard options.
Best for: 14-18 ft aluminum boats, jon boats, small pontoons, and inflatables.
Speed: ~15-25 mph (depending on boat weight & load).
Can plane most medium-sized boats (unlike smaller motors).
Handles 3-4 adults + gear comfortably.
4-Stroke (Most Common Today)
Pros: Fuel-efficient, quiet, no oil mixing, better for trolling.
Cons: Heavier than 2-strokes (~100-120 lbs).
2-Stroke (Older or Specialized Models)
Pros: Lighter (~70-90 lbs), simpler, more power per weight.
Cons: Requires oil mix, louder, less fuel-efficient.
4-Stroke: ~100-120 lbs (some models are lighter, like Tohatsu 15 HP at 97 lbs).
2-Stroke: ~70-90 lbs (easier to carry but rare new).
Manual start (pull cord) is standard; electric start available on some models.
External fuel tank (typically 6-12 gallons).
Fuel consumption: ~0.8-1.5 gallons per hour at full throttle.
Short (15") – Standard for smaller boats.
Long (20") – For deeper transoms (common on pontoons and inflatables).
✔ Fishing boats (great for trolling and getting on plane).
✔ Small pontoons & utility boats (ideal for lakes and rivers).
✔ Inflatable tenders (for yachts/sailboats).
✔ Duck hunting & shallow-water use (lightweight models available).
| Brand/Model | Type | Weight | Key Features |
|---|---|---|---|
| Tohatsu MFS15 | 4-Stroke | 97 lbs | Lightest in class, same as Mercury/Nissan |
| Mercury 15 HP | 4-Stroke | 97 lbs | Reliable, rebranded Tohatsu |
| Yamaha F15 | 4-Stroke | 99 lbs | Durable, saltwater-ready |
| Honda BF15 | 4-Stroke | 114 lbs | Ultra-smooth, very quiet |
| Suzuki DF15 | 4-Stroke | 97 lbs | Fuel-injected option available |
(Note: Some brands offer 9.9 HP & 15 HP in the same block, meaning upgrading is easy.)
✅ Pros:
Strong power-to-weight ratio (can plane medium boats).
More efficient than 20+ HP for small boats.
Available with electric start & charging (some models).
Great for fishing, trolling, and light cruising.
❌ Cons:
Heavier than 9.9 HP (harder to carry alone).
No power trim/tilt (manual tilt only).
Not ideal for heavy loads or rough offshore waters.
Yes, if:
You have a 14-18 ft boat and need more power than 9.9 HP.
You want better speed without the bulk of a 20+ HP motor.
You need a reliable motor for fishing, hunting, or light cruising.
No, if:
You have a heavy boat (18+ ft)—consider 20-30 HP.
You need power trim/tilt (look at 25+ HP models).
New (~$3,000-$4,500): Fuel-efficient, low emissions, warranty.
Used (~$1,200-$2,500): Older 2-strokes are lighter but less efficient.
A 20 HP motor is often only slightly heavier but offers more power.
A 9.9 HP motor may suffice if you don’t need as much speed.
