hi everybody... i'm new here and need some help. I have a 1982 20' "pierce arrow" open bow, OMC chevy350, I think a 800 stringer. I've had the boat about 7 years and have had the out drive rebuilt 6 years ago (because of an oil leak and they had said parts were still around once they opened it up). It has run fine and I baby it ( We ease it into gear and out of gear) but we use it for sking and tubing with the kids. The last time we took it out as we dropped a skier and I let off the throtle it made a loud "clunk", still in gear, I could could go back for them, BUT I didn't like what I heard. Any input would be great, I'm keeping my fingers crossed, because I couldn't buy another boat in these times. I tried to head problems off when i had money, but you know how that goes. thanks
