Small Outboard Boat Motors: Six Brands, One Honest Comparison
Ask five boaters which brand is best and you will get six answers and a lecture. We compared them on what actually matters: price, weight, features and support.
Small outboard boat motors are portable engines, usually 2 to 30 HP, made by marine brands such as Mercury, Suzuki, Yamaha, Honda and Tohatsu, plus electric makers like Torqeedo, to push dinghies, RIBs and small boats.
The sailing club brand war
At a small sailing club on a reservoir, the safety boat motor finally gave up after fifteen years. The committee meeting to choose a replacement lasted longer than most regattas.
Alan swore by Honda because his lawnmower had never failed. Maureen wanted Yamaha because the club had always had one. Young Callum pointed out that Tohatsu was cheapest and the treasurer went pale with love. Someone suggested electric and was politely ignored, then quietly agreed with.
In the end they made a spreadsheet. Price, weight, local servicing, fuel injection and whether the motor would start first pull on a frosty March morning. The shortlist narrowed to two 9.9 HP models within a few kilos of each other, and they picked the one with a dealer twenty minutes away.
The moral from the committee minutes: every major brand makes a good small motor, so choose on fit, features and who can service it near you.
Which brand of small outboard boat motor is best?
There is no single winner. Each brand has a clear strength. Prices are starting prices in USD from our stock.
| Brand | Small range we stock | Price span | Known for |
|---|---|---|---|
| Mercury | 2.5–30 HP | $1,150–$5,800 | EFI from 8 HP, wide dealer network |
| Suzuki | 2.5–30 HP | $1,080–$5,400 | Light weight, strong value |
| Yamaha | 2.5–25 HP | $1,160–$5,200 | Reputation for reliability, smooth running |
| Honda | 2.3–30 HP | $1,200–$6,300 | Quiet engines, air-cooled BF2.3 |
| Tohatsu | 2.5–15 HP | $1,100–$3,200 | Lowest prices, simple and light |
| Torqeedo | Electric, about 1–12 kW | $1,499–$9,199 | Silent, no fuel or oil changes |
Are the cheaper brands worse?
No. Lower price usually reflects fewer features, not poorer engineering.
Tohatsu and Suzuki keep costs down with simpler designs, often carburetted in the smallest sizes. Mercury and Honda add features like electronic fuel injection or specific quiet-running design on some models. For a 4 HP tender motor you use a few hours a month, the value brands make a lot of sense. For a 20 HP motor running long days, features such as EFI earn their keep in easier starting and economy.
- All petrol motors we sell are four-strokes.
- Carburetted motors appreciate fresh fuel and regular use.
- EFI models start more easily after long lay-ups.
One standout motor from each brand

How do I narrow down to one motor?
- Fix the horsepower. Use your boat’s maximum HP and aim for 60 to 90 percent of it.
- Fix the shaft length. Short for about 38 cm (15 in) transoms, long for about 51 cm (20 in).
- Compare the shortlist on weight. A few kilos matter if you lift the motor on and off.
- Check local service. Then pick the brand you like the look of. Seriously, that is allowed.
Small outboard boat motors: FAQ
What is the most reliable small outboard brand?
Yamaha, Honda, Suzuki, Mercury and Tohatsu all have strong reliability records. Servicing, fresh fuel and flushing after salt water affect reliability more than the brand.
Are Mercury and Tohatsu small motors the same?
Some small Mercury models have historically shared designs with Tohatsu, but specifications, features and support differ by model, so compare the exact motors you are considering.
Is an electric small boat motor as good as petrol?
For short trips and quiet waters, yes, and it needs far less maintenance. For long range or strong currents, petrol still offers more endurance per kilo carried.
Can I buy parts for any brand?
Service parts such as spark plugs, impellers and filters are widely available for all major brands through authorised dealers and marine chandlers.
