Choosing an outboard for a small boat comes down to one question: do you need extra thrust for a fishing or rubber boat, or is keeping the purchase price low more important? The HANGKAI 2-Stroke 3.5HP and the Outboard Boat Engine Motor For All Kinds of Small Boats 2 Stroke 2.3 HP 52CC both fit compact boats, but they answer that question differently.
Quick verdict
The HANGKAI 3.5HP is the stronger motor for anyone who wants more power in a compact outboard. Its air/water cooling and 1.3L built-in fuel tank suit longer trips on yachts, rubber boats, and fishing boats. The 2.3 HP 52CC is the lighter-budget option for small inflatable boats and rubber boats where a little less thrust is acceptable.

Where each product wins
The HANGKAI 3.5HP wins when you want more horsepower and a built-in 1.3L tank. Its listed applications include yachts, which points to a wider range of small boats. It also adds air/water cooling, which may be useful if you run longer distances on open water.
The 2.3HP 52CC wins on purchase price and simplicity. It lists for less than the HANGKAI, making it an easier fit for a tight budget. It is a 2-stroke engine with forced air cooling, a CDI ignition, and a 3-blade propeller, making it a straightforward choice for small inflatables and rubber boats. The 52CC displacement also gives you a quick sense of its size.
HANGKAI 2-Stroke 3.5HP Outboard Motor Air/Water Cooling Fishing Boat Engine

The HANGKAI 3.5HP brings the higher published horsepower of the two, and it pairs that with air/water cooling and a 1.3L built-in fuel tank. That combination makes it the pick for fishing boats and yachts where you want consistent power for longer stretches. Its aluminum alloy construction is described as anti-corrosion and anti-rust, and the CDI ignition is meant to make starting quick and easy.
The limitation is the price. It costs more than the 2.3HP 52CC, and if your boat is very small and you rarely need full throttle, the extra power may not feel necessary. There is also no displacement listing to compare directly, so the 3.5HP rating is the main figure to work with.
Outboard Boat Engine Motor For All Kinds of Small Boats 2 Stroke 2.3 HP 52CC

This 2.3HP outboard is the lower-priced option, making it a sensible pick for boaters who want to spend less. It is a 2-stroke engine with forced air cooling, CDI ignition, and a 3-blade propeller. With a displacement of 52CC, it slots into the very small outboard class and targets inflatable boats, rubber boats, and fishing boats. The manual trim and tilt mechanism and fuel mix ratio of 25:1 are listed for reference.
The trade-off is power. At 2.3HP, it will not push a larger boat the way the HANGKAI can, and its listed application leaves out yachts. If you need maximum thrust or plan to carry a heavier load, the lower horsepower will be the deciding factor.
Final choice by use case
Choose the HANGKAI 3.5HP if your boat can handle more thrust and you want a 1.3L built-in tank for longer trips. Choose the 2.3HP 52CC if you want a lighter-budget option for a small inflatable or rubber boat and you know 2.3HP will be enough.
