A friend of mine has this housboat and we were wondering if when we pull the boat and find the bearing bad is it a big job to replace it. Reason for pulling, they bot beached and when they got out there was a vibration on one engine and he thinks maybe he bent a prop there for causing a week bearing to get worse. there is no water coming in the boat or anything like that. I work on io's but never dealt with vdrives before. Thanks in advance.
