A bit more. Championship gearboxes are available and relatively not expensive. Their motors are a straightforward rebuild by a good motor electrics specialist.
There are a number of parts on the Santorin that are the same as the bigger and heavier Super Maramu. The C drive is one and I'm pretty sure the curled gearbox is another. Therefore they are well over engineered for the smaller Santorin and should last and last.
There's nothing like your first sudden tropical squall to make you appreciate the Santorin's curling system!
