They are pretty standard model aircraft three phase brushless outrunner motors. Here's a web page showing a stack of them, all different powers and sizes: http://www.hobbyking.com/hobbyking/store/uh_listCategoriesAndProducts.asp?catname=All+Outrunner+Motors&idCategory=63&ParentCat=59
These motors are easy to drive using a standard brushless motor controller, either one designed for use with sensorless motor electric bikes or ones like this designed for use with model aircraft motors: http://www.hobbyking.com/hobbyking/store/uh_listCategoriesAndProducts.asp?catname=All+Speed+Controllers&idCategory=61&ParentCat=182
I've made a few boat propulsion systems using model aircraft motors, but I adapt them so that I can use cheap electric bike controllers, as the bike controllers have nice features like cruise control, a reversing switch and current limiting (handy if the prop fouls).
If it were me, then I'd get hold of a sensorless electric bike controller, as that will mate directly to a twist grip electric bike throttle. The model aircraft speed controllers need to have a throttle kludged up from a servo tester, as they need a PPM signal to set rpm.
