Why is the 1900Kv rating ideal for high-speed marine propulsion?
The Spektrum 1900Kv motor for Sonicwake V2 and hydroplane hulls offers a high-RPM profile that translates into blistering speed across open water. Its Kv rating is optimized for 4S–6S LiPo setups, enabling rapid acceleration and sustained top-end velocity. This makes it ideal for deep-V hulls and hydroplanes where throttle responsiveness and speed are critical. Whether you're racing or pushing performance boundaries, the motor’s Kv output ensures consistent propulsion and control.
How does the inrunner design benefit tight hull configurations?
The Spektrum M-SPMXMM3300 4-pole inrunner motor with water cooling jacket features a compact rotor configuration that fits easily into confined hull spaces. The inrunner format supports direct-drive systems and high RPM operation, making it ideal for speed-focused builds. Combined with the 4-pole rotor, the motor delivers smooth throttle response and torque-rich acceleration, even under aggressive launch conditions. Its efficient layout also reduces drag and vibration, enhancing overall handling and durability.
What role does the water cooling jacket play in thermal management?
The Spektrum M-SPMXMM3300 with 3400W output and Smart ESC compatibility includes an integrated water cooling jacket that actively dissipates heat during operation. This feature is essential for marine environments where continuous throttle use can lead to thermal buildup. By maintaining optimal operating temperatures, the cooling system protects internal components and preserves consistent performance. For boaters pushing their setups to the limit, this thermal management system ensures that the motor remains cool, efficient, and responsive throughout the run.
How does Smart ESC compatibility enhance system performance?
The Spektrum Firma motor with ball bearings and high-RPM inrunner design is designed to pair seamlessly with Firma Smart Marine ESCs, including the 160A variant. This compatibility enables telemetry feedback, adaptive timing, and simplified setup, enhancing system awareness and control. The motor’s electrical specifications align with Smart ESC parameters, ensuring safe current handling and efficient power delivery. For users building Smart Technology-equipped boats, this integration offers a reliable and performance-matched solution.

- For orders above £120, we offer delivery to most mainland UK addresses. For orders under £120, we can still deliver to Northern Ireland and the outlying isles, as long as the item can be sent by Royal Mail, weighs less than 30kg, and fits within 61cm × 46cm × 46cm. Some highland and remote areas may carry an extra delivery charge as couriers often apply surcharges in these locations. If you live in one of these areas, feel free to contact us before ordering so we can confirm the delivery options and costs for you.
- Most of our products include delivery in the price. If your order is under £90, a small delivery fee will apply but do not worry this will always be clearly shown at checkout before you complete your purchase.
- Depending on what you choose at checkout, your order will usually be delivered either the next working day or within 2 working days. For next day delivery please place your order before 2:00pm. Orders are dispatched Monday to Friday only. Some items may take a little longer and if that is the case we will always show the expected delivery time on the product page.
- If your order includes items with different dispatch times we will normally wait and send everything together once all items are in stock. If one of the items is going to take a while we will give you the choice either wait for everything to arrive or let us send the available items now and deliver the rest later. It is up to you.
- We use trusted delivery partners to make sure your order gets to you safely and on time. We use DPD for next working day deliveries and Royal Mail for the 2 day option.
- As soon as your order is on its way we will send you a tracking number by email. If you provide your mobile number at checkout we will also send delivery updates straight to your phone so you can keep an eye on progress.
- If a product is marked as "Dispatched within 3 working days" delivery usually takes around 3 to 5 working days from when your order is placed.
- For customers in Inverness and other parts of the Scottish Highlands deliveries can take up to 2 working days even if you select next day delivery as couriers do not currently offer a guaranteed next day service to those areas.
