Product benefits
Built for the long run
01
Easy Installation
Only three small holes to assemble, sealed tightly with a special rubber sealant. No fiberglass work necessary.
02
Long Runtime
External placement gives more efficient water cooling — up to 7 minutes of continuous thrust without overheating.
03
Minimal Noise
About 80% noise reduction from the external placement of the engine, eliminating possible border cavitations.
04
Space Saving
The complete drive unit sits outside the hull. Only controls and power supply remain inside the boat.
05
Optimal Efficiency
A shorter transverse channel and ideal leverage deliver up to 40% higher efficiency than conventional systems.
06
Optimal Design
Hydrodynamic shape and ideal placement reduce water resistance to a fraction of conventional systems.
Specifications
