Hi Scott, if you can do some fabrication you
can get a pancake motor from any modern VCR
(capstan motor), these have a flat magnet
assembly and and a flat coil assembly.
Sometimes the bearing assembly is removable.
If you could rig the bearings up the electric
part could watertight with only the perm magnet
rotor and shaft in the water. :o)
