What motor ?

Hi every one.
Recently i finished building a Bait Boat for fishing, complete with bait hoppers and sonar. I decided to push it along with 2x1100 gallong per hour 12v pumps.
Wednesday saw its maiden voyage but to be honest i was a bit disappointed with the way it performed. It was ok but a bit slow. The pumps just didnt seem to have enough
humph
in them. So now i have decided to change things around and power it with 2 props. This boat is about 39" long and being made of fibreglass is a bit on the heavy side.
I was thinking of using 2x 3" 4 blade props as i have used these on a build i finished about a year ago ( Northsider ans Ironsider from Tyne Side Models) a pair of working tugs and these seemed to work very well and had loads of pulling power.
I was wondering if anyone could give me an idea of what motors to go for and with using 2 props would i need a lefthand and righthand screw.

Those motors are superb, but you will only need 6 volts.
They rev about 4000 on 6 volts, almost 9000 on 12 and fly on 18 volts, about 12000 but with a lot of torque.

Thats what i need loads of torque. They have got to move a fair bit of weight around especially at the start of the run.
Thanks for you help.

Just a quick reply, try a nozzle reducing the diameter of the outlet of the pump may help. But if you go for props opposite rotating props will be a slight advantage in keeping the boat in a straight line but not entirely necessary.
