2005 Larson Senza 186, Volvo Penta 5.0 GL-E, Volvo SX-m sterndrive. Boatin around lake hit a stump which bent one blade on the prop, we were at idle when it happened. Bought new prop and put it on, noticeable vibration from sterndrive around 1300-1500 rpms. Took the prop of cranked it up and could not see any wabble on the prop shaft. Looked at prop and it is being rubbed down at the outside lip that just sits in lower unit. Only on one side of prop though. Boat has 30 hours, engine is well taken care of still looks and runs like brand new. I wasnt able to figure out how to get prop shaft out, no manual for it and only slight knowledge. Bent shaft or bad propeller? or maybe something else? I can only ski in bathtub so long, Help
