Lisa & Neil:
The final answer from Scanmar was that they had fired their ''CPT guy'', they didn''t know what my unit was not performing properly, they therefore couldn''t ''fix it'', and they were willing to refund my money. Because the unit as designed & built should not be weaker on one tack than the other (essentially, the problem we''ve been having), I asked them to replace the Control Box (motor drive unit), burn it in and then ship it out. They agreed altho'' we''re now working on when they can do this given the 4th holiday coming up.
They just aren''t up to speed on this product as with their windvanes, but we like it enough we''re willing to accept the hassles. Hopefully, the next unit will be a bit more capable. I would not expect them to change the motor (and with it, the fundamental problem that we and several other boats have experienced) anytime soon.
