After lauch of our 1988 C30 MKII, I noticed a small stream of water coming from the rubber tubing that connects the packing box to the prop shaft thru hull (fiberglass tube part of hull). I repalced the clamps that hold the tube to the stuffing box and the clamps that attacht it tothe hull as well. No avail....still seeping water. I was going to wrap the pipe and see if that stopped the leak, but there is so little room under the pipe and between the hull,that I would not be able to get the clamps back on. I am in a quandry of deciding if to live with it for this year. Or haul out and fix..... I have watched it for a few hours at at time and the wate is not coming from the packing/stuffing box. If I haul, I am assuming it is the 4" long tube (looks like a piece of exhaust hose) that is rotted and seeping water. In case I do haul, so I can have the parts at the ready..... my question (finally), is what is the diameter of this tube? and could there be any other issues that I am missing. Could the fiberglass shaft tube be cracked/damaged??? Thanks for any and all input... Jeff Martin
