Upgrade Your RC Boat with This Complete 3S Outboard Motor – Small, Medium or Large
Bring your DIY yacht or fishing boat project to life with this fully assembled and tested outboard motor. Unlike simple plastic housings, this product includes a powerful motor (brushed or brushless depending on size), metal hardware, and all the critical components already installed. No guesswork, no missing parts – just a ready-to-use solution for your next aquatic adventure.
Whether you're looking for a compact setup or a high-powered engine for a larger vessel, this motor is available in three performance tiers: Small, Medium, and Large – each with its own internal configuration and optimized for different needs.
