Mercury Outboard Motors: The Full FourStroke Lineup, 2.5 to 30 HP
Mercury is the name on more transoms at the ramp than almost any other. Here is every small Mercury FourStroke we sell, in one list, with real prices.
Mercury outboard motors are gas four-stroke engines from Mercury Marine, one of the largest outboard makers. Their small FourStroke range runs from a 2.5 HP tender motor to a 30 HP fuel-injected three-cylinder.
Why Big Earl only buys one brand
Earl has run a bait shop beside the same public ramp for twenty-two years. When customers ask what motor to buy, he points out the window and counts. On a busy Saturday he usually gets to the third Mercury before he finds anything else.
His reasoning is simple and not very romantic: “When it breaks at 6 a.m. on a holiday weekend, which part can you actually find?” That is the real case for Mercury. Parts, service and people who know the engine are close to everywhere. Earl’s own jon boat wears a 9.9 EFI. He says it has started first pull for four seasons, and he says it loudly, near the register.

How does the Mercury range break down?
Think of it as three families: single-cylinder portables, twin-cylinder EFI mid-sizes, and three-cylinder EFI top models.

| 2.5 and 3.5 HP | 1 | Carburetor | Tenders, canoes, dinghies | $1,150 |
| 4, 5 and 6 HP | 1 | Carburetor | Inflatables, small sailboats | $1,620 |
| 8 and 9.9 HP EFI | 2 | Fuel injection | Jon boats, kickers, sailboats | $2,580 |
| 15 and 20 HP EFI | 2 | Fuel injection | 14 to 16 ft fishing boats | $3,500 |
| 25 and 30 HP EFI | 3 | Fuel injection | Skiffs, RIBs, 16 to 18 ft boats | $5,200 |
Who should choose a Mercury outboard?
- Buyers who want the widest possible dealer and parts network.
- Owners who want fuel injection on a small 8 to 20 HP motor.
- Jon boat and aluminum fishing boat owners (a very common pairing).
- Anyone who wants one brand from tender motor to main engine.
Mercury outboard motors: FAQ
Are Mercury outboards reliable?
Yes. Mercury FourStrokes have a strong reliability record, and the large service network makes repairs and routine maintenance easy to arrange.
Which Mercury outboard is best for a jon boat?
For a 12 to 14 ft jon boat, the 9.9 HP EFI or 15 HP EFI are the most popular picks. Check your capacity plate before going larger.
Do small Mercury outboards need oil mixed in the fuel?
No. Every Mercury we sell is a four-stroke with its own oil sump. You run straight gasoline and change the engine oil at service intervals.
What is the lightest Mercury outboard?
The FourStroke 2.5 HP, at roughly 38 lb. It suits tenders, canoes and small dinghies and carries easily by hand.
