I have a 1979 O'Day 25 that I sail on Lake Erie. During heavy weather sailing the outboard will rock back and forth, maybe 1/2 to 1 inch, on its bracket. It drives me nuts!!! The bracket is the original equipment. The transom is solid, the bracket seems solid. Is this "to be expected"? Has anyone experienced this and fixed it? PS: Love the boat...I just can't figure out if it's the perfect "big"-small boat, or the prefect "small"-big boat.
