Well the shaft appears to be straight, but the strut is more than likely bent. After pulling the shaft off, we saw that a section of the thread has a 'stretched' look to it. Not sure if that's suppose to be there or not. If it's stretched, we'd definitely want to replace it. Also, we tried pulling out the water pump impeller when winterizing the boat, and it's stuck in there pretty good. What do you guys use to pull it out without wrecking the blades?
