Choosing between two marine engines propulsion parts usually comes down to what your boat is missing: a way to start a big inboard engine, or a way to push a small boat through the water. These two products sit at opposite ends of that decision, and picking the wrong one means you'll still be stuck at the dock.
Quick verdict: If you need to replace a starter in an inboard engine, the Arco 70200 is the part you need. If you need outboard power for a small boat, the HANGKAI outboard is the unit to consider. They do different jobs, so your engine layout decides the winner.

Where each product wins
Where the Arco 70200 wins: If your boat already has an inboard engine and the starter is the problem, the Arco is a direct replacement component rather than a whole new propulsion system. It's listed as new, and it's the lower-priced item in this comparison. It doesn't make sense unless you have an engine for it to start.
Where the HANGKAI wins: If you need to move a boat and it doesn't have outboard power, the HANGKAI gives you a complete outboard motor with water-cooling. That's a capability the starter doesn't offer. It wins whenever propulsion is the missing link.
The key difference
The key difference between these two is simple: one is a component that goes inside an existing propulsion system, and the other is a complete propulsion system itself. The Arco 70200 only earns its place when there is already an inboard engine to start. The HANGKAI replaces the need for any other engine on a small craft. That distinction should guide your purchase more than price alone, though the $169.00 to $228.18 spread is worth noting.
Product notes
Arco 70200 Marine Starter Motor
If your Ford 302 or 351 marine inboard engine is turning over slowly or not at all, this starter is designed for that exact job. The Arco 70200 is listed as an OE-quality marine starter with CW (clockwise) rotation, and its compatibility includes MerCruiser, OMC, and Volvo Penta Ford-based installations. That makes it a strong candidate when you're replacing a worn starter in an existing inboard engine. The limitation is that it does not provide propulsion; it only cranks the engine that moves the boat. You also need to confirm your engine's rotation direction before ordering, because installing the wrong rotation can cause engine damage. This is a component-buying decision, not a full powerplant purchase.
HANGKAI 7.5HP Outboard Motor
Go for the HANGKAI if your project is getting a small fishing boat or inflatable onto the water. This is a 7.5HP outboard motor with water-cooling, and it gives you propulsion directly, which is something the starter cannot do. The main limitation is preparation: the motor does not ship with gear oil, and you need to add oil before the first run and replace it after the 10-hour run-in period. Gasoline engines are noisy, roughly comparable to a motorcycle, so expect motorcycle-level noise. For propulsion duty, the HANGKAI is the more capable choice, but it asks for more setup attention than a bolt-on starter.
Final choice by use case
Choose the Arco 70200 if you already have an inboard engine and the starter needs replacing. Choose the HANGKAI if you need outboard propulsion for a small boat. Let your engine setup decide, and you'll avoid buying a part that doesn't match your boat.
