It is a 1976 built Cal 2-27, 7600lb 27' LOA about 23' LWL and I think 9' 3" beam. Bank is 8 6v golf cart batteries in series, 220ah for 48v nominal. Controller is Kelly sine wave type, I think 500a. Motor currently is ME0201014201 BLDC (PMAC) motor and I was using a 2:1 cast iron enclosed reduction gearbox. Prop is 14" x 10" pitch, RH. I am currently building a new mount that will incorporate a thrust bearing and splined shaft and sleeve coupling, for use as a direct drive setup or with a reduction gearbox. I have another 14x10 prop that I have cut down to 13" and I will be trying that one, and I will be adding a bidirectional fan since the motor now turns the wrong way for the original cooling fan to operate most efficiently. I will also be replacing the bendy twisty warpy old bronze shaft with a nice new SS one, and a new Cutless bearing as well. I hope to see a very efficient setup in the end.

A small bilge pump, maybe. Or bait aerator pump. Golden might have a cooling pump designed for the motor. You might want to thermostatically control the pump to reduce pump run time and power consumption when it is not needed.
