Why stop with 3/4? Go 1hp and change the pulley to a larger size to speed up
the whole thing. (No I haven't done it...yet).

the C6C17WB2K is a 3/4HP washdown single phase motor in the same NEMA 56 frame,
so it should swap out with no problem. You'd want to check to make sure the
shaft configuration, etc. is the same. (i.e. is a 1J the 1/2 HP and the 2K the
3/4 HP, otherwise identical, or should you be getting a 1K or a 2J... the
leeson catalog would tell all)
Cat #112432 vs 112431

You'd also want to check the electrical ratings on the controller (Locked Rotor
or start current, for instance..)
Full load for the 3/4 HP is about 11 Amps, 9 Amps for the 1/2HP
