A twin propeller unit which adds a new dimension to the convenience of a bow thruster. Having two propellers supplying equal on both sides greatly increases manoeuvrability and ease of boat handling.

Made to Last
Consisting of high‐grade, durable materials, the TwinProp is made to last. The high efficiency motor supplies unrivalled thrust. The cast, balanced four‐blade propellers are exceptionally strong and highly reliable. In addition, all components of the TwinProp that come into contact with the water are made of stainless steel.

All this makes the TwinProp a piece of equipment of great technical perfection which is reflected in, amongst others; ground precision gears, special oil/water seals with stainless steel springs and a torsionflexible
rubber safety coupling with ball bearings throughout. In case of failure of one propeller the unit still allows you to manoeuvre both sides.
