Universal secondary pulley for standard couplings
4 versions available depending on your coupling and the desired belt (SPA V-belt or HTD 8M30 timing belt):
SPA 125mm: inner diameter 50mm, outer diameter 125mm
HTD 8M30 48 teeth: inner diameter 50mm, outer diameter 127mm
These two models are compatible with TP001, TP002, TP003, TP004, TP005, TP006, TP007, TP008, TP009 couplings.
SPA 151.1mm: inner diameter 63.5mm, outer diameter 151.1mm
HTD 8M30 64 teeth: inner diameter 63.5mm, outer diameter 168mm
compatible with TP001, TP002, TP003, TP004, TP005, TP006, TP007, TP008, TP009, TP011, TP012, TP013, TP014, TP015, TP018 couplings.
Operating principle and advantages:
Designed to accommodate a toothed belt 30mm wide with an 8mm pitch, this pulley ensures full and immediate torque transfer from the electric motor, with no loss of grip. It allows 100% electric navigation
Safety through slipping: Connected to the electric motor by a V-belt, the pulley provides natural mechanical protection. In the event of a sudden underwater propeller blockage, the trapezoidal profile allows the belt to slip. This slipping acts like a fuse, thus preventing damage to your transmission.
Below is the pulley compatibility table with the different couplings:
