Choosing marine engines propulsion for your boat usually comes down to one practical question: how much power do you need and where can you install it? These two engines sit at opposite ends of that decision. The HANGKAI is a small outboard for fishing boats, rubber boats, and yacht tenders. The Dodge V10 Indmar is a large inboard engine aimed at bigger hulls. The price gap between them is just under $9,272, and the power gap is just as wide.
Quick verdict
For a small boat that needs simple, self-contained power, the HANGKAI outboard is the practical buy. For a large inboard boat or repower project, the Dodge V10 Indmar has the power, but you will spend a lot more and you are committing to an inboard V10.
Price comparison
| Product | Listed Price | Power | Notable Spec |
|---|---|---|---|
| HANGKAI 2-Stroke 3.5HP Outboard Motor Air/Water Cooling Fishing Boat Engine | USD 228.17 | 3.5 HP | Built-in 1.3L fuel tank |
| Dodge V10 8.0L Indmar Marine Inboard Boat Engine Motor Brand New 0 Hours | USD 9,500.00 | 305 HP | 450 lb-ft torque |
Where each product wins
- HANGKAI wins when the goal is keeping costs down. The price spread in the table shows how much less you pay for the outboard, and it comes as an outboard rather than an inboard.
- Dodge V10 wins when the goal is moving a larger hull. The power and torque numbers in the comparison table put it in a completely different propulsion class. It is an unusual option for an inboard repower.
Product notes
HANGKAI 2-Stroke 3.5HP Outboard

This new outboard combines a compact 3.5 HP motor with air/water cooling and a CDI ignition for easier starts. It uses a built-in 1.3L fuel tank, and the aluminum alloy construction resists corrosion and rust. At USD 228.17, it gives small-boat owners a lower-priced propulsion option.
The limitation is power. A 3.5 HP engine is best for lightweight craft and short trips, not for heavy hulls or high-speed running. If you plan to stick to a fishing boat, rubber boat, or yacht tender near shore, it will do the job. If you need more speed or a bigger payload, you will want more horsepower before you leave the dock.
Dodge V10 8.0L Indmar Marine Inboard

This is an inboard engine that has never been fired and shows zero hours, making it a unique option for someone restoring or repowering a boat. It uses a Dodge V10 8.0L platform with an iron block, built by Indmar for marine use, and it is rated at 305 HP with 450 lb-ft of torque. At USD 9,500.00, it is a significant investment.
The limitation is condition and fit. It has spent its life as a show piece, so a few scrapes and scratches have appeared over the years, and it carries no warranty. It is also an inboard V10, which means you need a hull and installation setup that can handle that size. Buy it if you are ready for a large project and want a powerplant that has never run.
Final choice by use case
- For a small fishing boat, rubber boat, or yacht tender, the HANGKAI outboard is the pick. Between the two prices shown above, it is the lower-priced choice, and the outboard's power rating is enough for nearby cruising.
- For a large inboard hull or a repower project, the Dodge V10 Indmar is the pick. The price gap between the two engines tells you what you are trading away, but the V10's power and torque put it in a different class.
