Hello,
Bevel gear or worm drive off the drive axle
 onto a prop shaft would do it for you.

another possibility is having paddles/ vanes on the inside face of the back wheels...


or stick them on all four if it's 4WD and the steering is sorted too.

I did that once on a model DUKW using the big plastic Meccano wheels, just addedvanes to the inside rims, it wasnt fast but it worked.
