Hi all newbie here! Purchased this prop from ebay put it on for a quick sea trial before winterizing. Just bought an 84 Bayliner Ciera 2450 Sunbridge. Prop that was on it was hosed. Previous owner took the prop out so I got this ebay special prop. It's a 15x 19 volvo long hub. Boat vibrates like hell above 2500rpm. Does it going straight or into turns. Goes away at idle. Does this prop look bad? The mounting cone is off center on the lower unit when installed also. The hub looks a little off and the washer is oblong also.
