When you're shopping for marine engines propulsion, the first decision is how much power your boat really needs. A compact outboard may be all you need for quick trips near shore, but a fishing trip with passengers and gear changes the math. You're choosing between the GDRASUYA10 3.5HP 4HP 6HP 7HP Outboard Boat Motor Engine 2 Stroke 4 Stroke Water Cooling and the HANGKAI 6-12/HP 2/4 Stroke Outboard Motor Fishing Boat Engine Water/ Air Cooling.
That decision comes down to three things: how much thrust you need, how you plan to cool the engine, and how much you want to spend on the motor itself.
Quick verdict
If your main priority is keeping the cost down, the GDRASUYA10 is the pick. If you need more power for a fishing boat with passengers, the HANGKAI is worth the $51 jump.

|---|---|---|---|---|
| GDRASUYA10 3.5HP 4HP 6HP 7HP Outboard Boat Motor Engine 2 Stroke 4 Stroke Water Cooling | USD 187.75 | 3.5HP, 2.5kW max output | Water-Cooling | Light boats and lower listed price |

Where each product wins
The GDRASUYA10 wins on price. It's the more affordable option in this head-to-head, and that makes it easier to choose if you're watching your spending. For solo trips on a lightweight hull, it's the easier call.
The HANGKAI wins on power flexibility and its clear fishing-boat intent. It's designed for boaters who expect to carry passengers and gear, and it gives you more room to grow before you need a bigger motor. For group outings or days when you're carrying camping and fishing gear, it gives you more headroom before the motor feels like it's struggling.
Product notes
GDRASUYA10 3.5HP 4HP 6HP 7HP Outboard Boat Motor Engine 2 Stroke 4 Stroke Water Cooling
This outboard keeps the cost down while giving you a water-cooled 2-stroke engine rated at 3.5Hp. With a maximum output of 2.5kW and a full throttle operating range of 4000-5000r/min, it's built for steady, predictable running. The 6.7-inch three-blade propeller is designed to cut through water resistance, and the gear ratio of 27/13 helps translate engine rpm into usable thrust. Choose it if your boat is on the lighter side and you want a simple, affordable outboard motor. The limitation is the fixed 3.5Hp output. If your boat regularly carries heavy loads or more than one or two people, this motor may feel underpowered.
HANGKAI 6-12/HP 2/4 Stroke Outboard Motor Fishing Boat Engine Water/ Air Cooling
The HANGKAI is positioned for fishing boat use and comes with a 4HP & 4-Stroke engine that runs on air cooling. The product name also references a 6-12/HP range, so there's a clear sense that this motor is meant for more demanding loads. On a boat weighing up to 100kg with up to four people, the motor should move the boat, though the maker points out that speed changes with load. The main tradeoff is that you'll need to run it in water. Starting it on the bank or running it out of water can lead to cylinder scoring.
Final choice by use case
For a light boat and the lower listed price, choose the GDRASUYA10. For a fishing boat with passengers and gear, choose the HANGKAI.
