70” or 72” WW on a 220
Currently run a 70” water walker on a 220 13’6” cottonmouth. Just wondering what I’d gain or lose swapping hubs and going to a 72”

If you swap them out, you will say it has better low end push but you lost a little snap. If somebody swapped it out and didn’t tell you, you probably wouldn’t notice anything different.

I would choose the 72 for mor push.... plus if you modify the engine with Aircraft cylinders even 0470 cylinders would be better off with the 72”
Good Luck
