I run a H-5 or H-7 "most" of the time. The 1450 is another good choice.

with the heavier boat you might have better luck with the 1445

If you've never run a .21 rigger or even that boat, I'd start small, that motor and hull will run ok with a 215 or a 220 prather to start, easy to launch and dial in, then I'd move to the h series and some of the 1400 sreies. You probably will end up with a 1445 or an h-7. .21's are hard to launch with that much prop and need to be tuned up just right. If I had 1 prop to buy for a .21 I was going to play with it would be a 220 s/s prather.
