PJ,
I recently stumbled across an advertisement for the UK company,
Electronize Design, and checked out their website at
<
www.electronize.co.uk>. They sell motors, speedcontrols, etc. which
probably would work best in speed type boats. The part that really
caught my attention is that they include a very clear graph of the
current draw/amps etc. that can be expected when using one of their
motors. It would be great if all dealers would do a similar service to
the end users like us. I would suggest you check it out if only to add
to ones own enlightenment. Maybe I'm simpleminded but I was impressed
especially after your extolling the virtues of ammeters. They have one
of these by the way that sells for L8.95 which I have no clue would be in
U.S. dollars.
