"Another object of this. inventionyis: to provide
in a current motor, means for“ supporting the
is motor relative to‘the water so. that, when desired,
the. motor may be quickly removed from or re
placed in the water, thus making it‘possible to
position the motor or machine at a point out

of the movement‘ 'of' the stream of water. Each
pontoon I0 is provided with a keelv II'I at the
bottom thereof soas to prevent. lateral'swinging
movement of these pontoons in. the water.
A motor frame;.generall’y designated as I8, is
disposed between the two pontoons' I0 and. be
