Looking for an affordable outboard for a dinghy or small fishing boat? This 3.5hp manual-start, 2-stroke gas engine is listed at USD 197.76 and includes extras like a water pump impeller and fuel mixing bottle. Here's what to weigh before you buy.

Last updated Aug 17, 2026

Choosing an outboard for a small boat usually comes down to balancing power, weight, and starting convenience. If you're shopping for a dinghy or a compact fishing boat, a 3.5hp motor can be enough to get you moving without the expense and complexity of a larger engine. But manual starting and 2-stroke fuel mixing aren't for everyone.

Quick verdict

This 3.5HP 2-stroke gas outboard motor is a straightforward power option for small craft. It's priced at USD 197.76 and comes with a water pump impeller, starter, funnel, and fuel oil mixing bottle in the package. If you're comfortable mixing gas and oil at a 35:1 ratio and pulling a starter rope, this is a practical way to power your dinghy. If you'd rather avoid manual starts or mixed fuel, you may want to look elsewhere.

Who it suits

This motor is aimed at owners of dinghies and small fishing boats. With a 3.5hp output and a full-throttle operating range, it's not intended for large watercraft. The manual start system means you'll be pulling a cord, so it works best for someone who doesn't mind a bit of physical effort each time they head out. The listed speed of 12km/h with four people aboard gives a sense of its pace-it's more about getting from place to place on calm water than about planing at high speed.

What stands out from the listed details

The motor uses high-quality aluminum alloy, offering high hardness, anti-corrosion, and anti-rust properties. That's a practical advantage in a saltwater environment. The CDI ignition system is a common electronic ignition found on many small outboards. The 3.5hp (2.5kW) output is typical for a motor in this class.

The package includes useful extras: a water pump impeller, a starter, a funnel, and a fuel oil mixing bottle. Having these in the box means you can get set up without buying additional items separately. The engine height is about 16cm/6.30in, with a propeller length of 18cm/7.09in and an adjustment rod length of 40cm/15.75in-handy dimensions when checking whether the motor will fit your boat's transom.

Meaningful trade-offs

First, the 2-stroke engine requires a fuel-to-oil ratio of 35:1. That means you'll need to mix regular unleaded gasoline with 2-stroke oil before every outing. It's not difficult, but it adds a step that 4-stroke owners don't deal with. Second, the manual start system requires pulling a starter cord each time. If you have limited upper-body strength or want effortless starts, that's a drawback. Third, 3.5hp is an entry-level power level. It's matched to a dinghy or small fishing boat-not a vessel that needs to push heavy loads. The listed speed of 12km/h with four people gives a realistic sense of its capability, though actual performance depends on boat size, load, and water conditions.

Bottom line

At USD 197.76, this 3.5HP 2-stroke outboard motor offers a no-frills way to power a small boat. Its aluminum alloy construction and included maintenance parts make it an interesting option for budget-conscious boaters. Just be prepared for manual starts, fuel mixing, and the limitations that come with a 3.5hp engine. If those trade-offs work for your boating style, this motor could be a good match for your dinghy.
