Choosing a small outboard motor is one of the most direct marine propulsion decisions you'll make: keep the purchase price low and the fuel tank generous, or pay more for extra thrust and a longer engine cycle. That decision is especially important for anglers and weekend cruisers who don't want to over-spend on power they won't use, but also don't want to be left wishing for more push when the tide turns. The HANGKAI 2-Stroke 3.5HP and the 5.5HP 4-Stroke sit on opposite sides of that trade-off. One is built for light craft like fishing boats and tenders; the other targets small boats with a 52CC displacement. Here's how to decide between them.
Quick Verdict
If you need maximum thrust for a small boat that can handle it, the 5.5HP 4-Stroke is the more capable engine. If you want the lowest cash outlay and a motor that will happily push a lightweight fishing boat, the HANGKAI 2-Stroke 3.5HP is the more economical pick. The price gap is $37.18 in the HANGKAI's favor. For most light-duty fishing boats, the HANGKAI will feel sufficient; for faster trips or heavier loads, the 5.5HP is the one to choose.

Where Each Product Wins
Once the spec table is in front of you, the decision narrows to a simple question: do you want the bigger tank of the 2-stroke, or the extra thrust of the 4-stroke? For a lightweight fishing boat or tender where you rarely carry much, the HANGKAI's larger built-in fuel tank is hard to beat. For a boat that can take more power, the 5.5HP's higher output gives you a clear performance gain.
Product Notes
HANGKAI 2-Stroke 3.5HP Outboard Motor
The HANGKAI's big selling point is its 1.3L built-in fuel tank, which gives you more fuel on board without extra cans. The motor spins up to 5,000 rpm, so you get a reasonable range of throttle response for a small engine. It's described for use on yachts, rubber boats, fishing boats, and similar light craft, so it fits the classic tender role. The CDI ignition helps with quick starts, and the aluminum alloy build is aimed at corrosion and rust resistance. For light boats, the output is enough to move you along, but not to push heavy loads or plane aggressively. The lower power keeps it on the lightweight end of the spectrum, so set your expectations for moderate speeds and shorter distances.
5.5 HP 4 Stroke Outboard Motor
This motor brings noticeably more thrust for boats up to 8.2 feet in length. It produces 1.82kW and spins to 8,500 rpm, so it has a wider performance window for getting on plane with a light load. CDI ignition and a user-friendly handle simplify operation, and the listed 3-year warranty supports a long-term purchase. The trade-off is the 0.7L fuel tank: the stated 40-70 minutes of running time per fill means you may need to carry spare fuel on all-day trips. With its higher output, it's the better fit for a small boat that can handle the extra weight and thrust. For repeated outings with a loaded tackle box, the extra power gives you confidence against wind and current.
Final Pick by Use Case
For calm-water fishing trips around the dock, the HANGKAI is the natural match. For longer runs or bigger loads, the 5.5HP is the stronger choice.
