    Hello, I have a 1998 52' Viking princess with twin 3192 cat 660 hp. The drive shafts seam to be 3 1/4 " and leaking steady flow . Tightened to the max, still flowing. How dangerous to pick out old and repack while in my slip? Getting nervous

    It s usually done in the water. Make sure you have your tools and the packing material ready and precut it. Nothing a healthy bilge pump can’t handle
