Key features of the Dynamite P-DYNM3870 90A Marine ESC
- 90A continuous current – supports high-output brushless motors for small to mid-size RC boats
- Waterproof housing – protects internal electronics from splash, spray, and submersion
- Forward-only drive – optimized for jet propulsion and directional hull designs
- Built-in BEC – powers receiver and servos directly from the ESC
- EC3 connectors – ensure secure, high-current connections with LiPo battery packs
- Fixed throttle settings – simplifies setup and ensures consistent performance
How does the Dynamite P-DYNM3870 support marine propulsion?
The Dynamite P-DYNM3870 forward-only ESC for jet boats, deep-V hulls, and airboats is engineered for directional propulsion systems where reverse functionality is unnecessary or undesirable. Its forward-only configuration ensures smooth acceleration and predictable handling, especially in hull designs that rely on water jet thrust or directional rudder control. This makes the ESC ideal for platforms like the Pro Boat River Jet 23" and Aerotrooper 25", where backing up is not part of the operational profile.
Why is waterproofing critical in RC boat ESCs?
The Dynamite P-DYNM3870 waterproof ESC with EC3 connectors and built-in BEC features a sealed enclosure that protects sensitive electronics from water intrusion. Whether you're navigating splash zones, cutting through wake, or operating in rainy conditions, the waterproof housing ensures uninterrupted performance and long-term reliability. This design eliminates the need for external waterproofing measures and allows users to focus on driving rather than protecting their gear.
What power systems does the Dynamite P-DYNM3870 support?
The 2–4S brushless marine ESC with waterproof housing and non-programmable low-voltage cutoff is compatible with 2S–4S LiPo batteries, covering a voltage range of 7.4V to 14.8V. This flexibility allows users to tailor their power setups for speed, torque, or runtime depending on hull type and water conditions. The ESC includes a built-in BEC to supply regulated voltage to the receiver and servos, streamlining onboard power distribution without requiring additional components.
Is the Dynamite P-DYNM3870 programmable?
No. The Dynamite P-DYNM3870 with 90A continuous current, EC3 connectors, and fixed throttle settings is designed for simplicity and reliability. It features non-programmable throttle and protection settings, making it ideal for users who prefer plug-and-play operation without the need for software or tuning. This fixed configuration ensures consistent performance across sessions and reduces the risk of misconfiguration or setup errors.
Which RC boats are compatible with this ESC?
The RC boat ESC for Pro Boat River Jet 23" and Aerotrooper 25" with forward-only dri is a direct fit for several Pro Boat models and other platforms in the 23–25 inch class. Its compact form factor, waterproof design, and EC3 connectors make it easy to install and integrate into existing systems. Whether you're upgrading a stock ESC or building a custom setup, the Dynamite P-DYNM3870 offers reliable performance for brushless-powered marine applications.
Is this the best waterproof ESC for compact marine platforms?
For users seeking a durable, forward-only controller, the best waterproof marine ESC with 2–4S LiPo support, EC3 connectors, and built-in BEC delivers a balanced combination of simplicity, reliability, and performance. The Dynamite P-DYNM3870 is optimized for small to mid-size brushless RC boats that operate in wet environments and require consistent forward propulsion. Its fixed settings and sealed construction make it a dependable choice for hobbyists who value ease of use and rugged design.

We want to make sure your delivery goes smoothly, so here are some important details about our service:
- 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.
