I have a SHO VMAX 25P prop B&B'd by Croxton on a 2018 SHO VMAX 250 (flashed to 300) and it is eating thrust washers. On my second washer now and the prop gap is almost down to the Lower Unit case after only 15 hours. Tempest prop I have does not do this on the same boat. Any ideas why this is happening? It did not happen at all with this prop before the B&B by Croxton.
