We have Sharki 181 with a Valeo 25 amp shaft alternator.
It is a Type A290, this number has now been changed to 510837. I it is identical
to a Motorola unit, they look as though they come out of the same factory and
use the same brush set etc.

The current replacement has a UK list price of approximately £1200.00, yes one
thousand two hundred pounds! So I would suggest that you get yours repaired or
find a more sensibly priced alternative.

You should bre able to find an auto shop that can test and repair your existing
unit.
Best of luck.

Regards
Graham

Could somebody provide the specifications on the shaft driven alternater so
that I can have my current model checked. I get no output at 6 kts thru the
water... Does any body recommend a permenant magnet alternater.
