Why is the 4-pole inrunner configuration ideal for marine propulsion?
The Spektrum M-SPMXMM1000 4-pole inrunner motor for Pro Boat Blackjack 42" 8S features a rotor design that enhances torque delivery and throttle smoothness. The 4-pole configuration provides balanced magnetic interaction, reducing cogging and vibration during acceleration. This is especially critical in large-scale catamarans and deep-V hulls, where consistent thrust and directional control are essential. The inrunner format also supports higher RPM ranges, making it ideal for high-speed marine applications where rapid response and sustained velocity are required.
How does the cooling sleeve improve thermal performance?
The Spektrum M-SPMXMM1000 with high-efficiency rotor and water-resistant design includes an integrated cooling sleeve that actively dissipates heat during operation. This feature is vital for 8S brushless boat builds, where prolonged throttle use can generate significant thermal stress. By maintaining internal temperatures within safe limits, the cooling sleeve protects motor components and preserves output consistency. Combined with the motor’s 84% efficiency rating, this thermal management system ensures reliable performance across extended runs and aggressive driving conditions.
Is this motor compatible with high-voltage LiPo setups?
Yes. The Spektrum M-SPMXMM1000 sensorless motor with 6.5mm bullet connectors for 2S–8S LiPo supports a wide voltage range from 8.4V to 33.6V, making it suitable for both entry-level and advanced marine builds. Its sensorless architecture simplifies installation and reduces mechanical complexity, while the 6.5mm bullet connectors ensure secure, high-current connections with compatible ESCs. For users operating 8S systems, the motor delivers up to 4000 watts of power, enabling blistering acceleration and top-end speed without compromising control or reliability.

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.
