Do you need a motor to push your boat, or new supports to hold an existing engine? That's the decision between the HANGKAI 2 Stroke Outboard Motor 18hp and the INBOARD ENGINE MOTOR MOUNTS DF100 PAIR. They're both part of marine engines and propulsion, but they solve different jobs. One is a power source; the other is a structural component.
Quick verdict
If you need a full outboard engine, pick the HANGKAI. It has manual start, forward-neutral-reverse, and a 24L fuel tank. If you need replacement inboard engine mounts, pick the DF100 pair. They're low-profile cast aluminum mounts with corrosion-resistant plated steel parts. The $978.85 price gap reflects what you're buying: a motor versus mounts.
Price and specifications at a glance
| Product | Listed Price | Price Position | What to Know |
|---|---|---|---|
| HANGKAI 2 Stroke Outboard Motor 18hp | USD 1,098.80 | 246cc two-stroke outboard with water cooling and tiller control | |
| INBOARD ENGINE MOTOR MOUNTS DF100 PAIR | USD 119.95 | Pair of aluminum inboard motor mounts |
Where each product wins
- Propulsion: The HANGKAI is the one that moves a boat.
- Engine support: The DF100 mounts are the ones that hold an inboard engine in place.
- Not interchangeable: The DF100 pair is a complement for an inboard drivetrain, not an alternative to a full outboard.
Product notes
HANGKAI 2 Stroke Outboard Motor 18hp
This is the product to pick when you need a complete outboard package. The 18HP rating comes from a 246cc two-stroke engine with water cooling. It includes a 24L/6.34gal fuel tank, manual tilt, tiller control, CDI ignition, and forward-neutral-reverse gear positions, so it can handle both maneuvering and open-water cruising. The motor starts manually, making this a straightforward, hands-on setup. The main limitation is its transom fit: the plate height is listed at ≤44cm/17.32in, so if your transom is taller than that, this outboard won't fit properly. It also needs a 50:1 mixed oil-fuel ratio, which means you'll be mixing fuel at every fill-up. If you're new to outboards, the manual start and CDI ignition are simple to learn.
INBOARD ENGINE MOTOR MOUNTS DF100 PAIR
This purchase is for an inboard engine setup, not a bolt-on outboard. The DF100 pair is a set of heavy-duty cast aluminum alloy mounts with an elastomer element that resists oil and fuel, plus zinc dichromate-plated steel parts. They need only 1-7/8 inches of clearance, which makes them useful for lower-profile installations and tight engine compartments. They are built for 4-point mountings up to 850 pounds and are made in the United States. The set is sold as a pair, so you get both mounts needed for a two-side support arrangement. The limitation is that these are mounts only: they won't provide power, so if you need something to drive the boat, you need an actual engine to mount on them.
Final choice by use case
Choose the HANGKAI outboard if you need a complete propulsion unit for a small fishing boat and your transom is no higher than 17.32 inches.
Choose the DF100 motor mounts if you have an inboard engine that needs new mounting hardware, want a corrosion-resistant mount pair, and already have the engine and drive system in place.
For a new outboard-powered boat, the HANGKAI is the direct route. For an inboard mount replacement or rebuild, the DF100 pair is the component you need.
