MODEL 300 S · BOW OR STERN
Simplex Thruster
German quality, Swiss precision. Almost triple the operating time of a comparative electric tunnel system — 25 minutes per hour — backed by a 3-year warranty and zero maintenance beyond bottom paint.
PRODUCT BENEFITS
Engineered for the way boats actually dock
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.
SIMPLE & QUICK INSTALLATION
Drill one 50 mm hole. That's the hard part.
The S/S through-hull fitting comes with a watertight seal — no fiberglass work needed. S/S rods bolt through two pre-drilled 18 mm holes for a secure, rigid installation.
MODEL SPECS
Simplex 300 S

I-BOX
The system control center
Provides delay between drive directions, monitors solenoid functions to reduce the chance of lock-in, and stops the thruster in case of a locked-in solenoid — with no extra user action.
