2 months ago i had to take my prop to the shop to get it re-hubbed. now only 4 or 5 trips to the lake later my hub has spun out again. (atleast im about 95% sure it has) What could be causing this to keep happenig? What could i do to prevent this? New prob? Any help would be greatly appreciated as i can't afford to keep getting it re-hubbed. Thanks.
