I have a 1993 WA 22 ft, QUEST Boat,( made by Four Winns ) with a 200 Johnson Engine. It is an excellent boat, very confortable and dry in high tides. Now I have seen near the upper ends of the transom some gelcoat cracks, possibbly due to the Engine vibration. Is that normal? Does someone have a similar boat? Does it worth to repair the gelcoat or they will appear again?
