When we purchased the boat, a friend of ours who also keeps his boat in the same marina where we purchased QUANTA noted that the articulating outboard bracket was mounted too high. “When you pitch fore and aft in a seaway [hobby-horsing, that is called], your prop is going to pop out of the water as your bow dips down.”
Our friend Don Jordan made that comment as we were going over the boat, post-purchase. My thinking at the time, just wanting to start using the boat without having to spend any more money (haha!) or monkeying around with it further, was that if it was good for how many previous owners, it would last a bit longer the way it was.
