Hi Mark, can you tell me the weight of the hi torque MMB900 and do you supply a motor mount to install? (A pic and price would be really helpful.)  :-)

Hi, the motor weighs approx 600g. I supply a machined aluminium motor mount complete with stainless steel Allen head screws for these motors for 5 each.

I can vouch for the 900 - a lovely motor.

With its slow running capability perfect for a large or even a medium sized boat
