The video shows a man building a full propulsion and steering system for a small inflatable raft using only PPR pipes and two mini propellers. The PPR tubing holds the wires, supports the propellers, and even forms a functional rudder—much like a scaled-down boat engine. Once powered on, the dual propellers generate surprising thrust, instantly turning a simple 2.6-meter toy raft into a fast, maneuverable mini-speedboat.
PPR pipe, made from polypropylene, is commonly used in household plumbing and heating systems because it’s safe, durable, and long-lasting. It’s corrosion-resistant, lightweight, and connects securely through heat-fusion welding, ensuring leak-free joints.
These same qualities also make PPR practical for certain marine applications. Modified and reinforced PPR can handle seawater corrosion, its low weight reduces load on small vessels, and its reliable fused joints maintain strong sealing in complex pipe layouts. This combination of durability, stability, and easy assembly is what allows even a DIY builder to create a functioning boat propulsion system entirely from PPR tubing.
