Choosing among RC boats & aircraft often comes down to one important question: do you want a complete boat for on-water racing, or a motor component for a hands-on build or replacement? The DEERC and 3660 3680 sit at opposite ends of that decision, so the right choice depends more on project scope than on price alone.
Quick verdict
Choose the DEERC Brushless 35+KPH RC Boat Hobby Grade Remote Control Racing Boat for Adult if you want a complete racing-boat format with a 16-inch hull, two 3S batteries, water cooling, and a portable carry case. Choose the 3660 3680 Brushless Motor 3250KV 1250KV Water Cooling Jacket for RC Boat if you already have an RC boat project and need a single motor component with hobby-grade positioning.

| 3660 3680 water-cooling-jacket motor | USD 71.51 | Single RC boat motor | Hobby Grade, water cooling jacket, replaceable rotor, 4-pole and 12-slot design |
The listed price spread is USD 58.48, placing the DEERC higher while also giving it a much broader equipment package. The 3660 3680 keeps the purchase centered on one component.
Where each product wins
- DEERC: The clearer choice for someone who wants a named RC racing boat rather than a parts-focused project. Its listed 35+ KPH rating, 16-inch hull, two 3S batteries, and carry case create a more complete starting point for boat use.
- 3660 3680: The better fit for a builder or hobbyist shopping around a single motor. Its title specifies a water cooling jacket, and the hobby-grade designation matches a component-oriented RC project.
- Price: The 3660 3680 is the lower-priced route at USD 71.51, while the DEERC costs USD 129.99. That USD 58.48 difference matters if the rest of the boat setup is already covered.
Product notes
DEERC 35+KPH Hobby Grade RC Racing Boat
The DEERC boat is the choice for a shopper who wants a complete RC racing boat rather than a standalone component. Its 35+ KPH rating, 16-inch racing hull, built-in water-cooling system, two 3S batteries, and portable carry case point to a fuller on-water package. The metal servo and shaft are also called out as part of its control and drive hardware. The limitation is focus: the title specifically frames the boat for adults, so it is not the direct match for someone shopping for a replacement motor or a workshop component. At USD 129.99, it also sits at the top of this comparison, with a USD 58.48 gap separating it from the motor.
3660 3680 Water-Cooling-Jacket RC Boat Motor
The 3660 3680 makes more sense when the project starts with an RC boat that needs a component. Its title identifies a water cooling jacket and a single motor, while the hobby-grade designation suits a hands-on build or replacement decision. The description adds a 4-pole, 12-slot design, a 6061T6 aluminum heatsink, copper windings, ABEC5 bearings, and a replaceable rotor, giving the motor specific hardware details to compare. The trade-off is scope: it is a component choice rather than the remote-control racing-boat format. Its listed age level of 17 Years & Up also points toward an adult hobby project instead of a general family-oriented purchase.
Final choice by use case
- For racing on the water: Pick the DEERC, because the listing combines a 35+ KPH boat, 16-inch hull, two 3S batteries, water cooling, and a carry case in one purchase.
- For a motor replacement or custom RC build: Pick the 3660 3680, because it is identified as a single hobby-grade motor with a water cooling jacket and replaceable rotor.
- For the lower listed price: Choose the 3660 3680 at USD 71.51.
- For the broader boat package: Choose the DEERC if its USD 129.99 price fits the project and you want the boat-focused equipment described above.
