Re: shaft seized to power head-your experience
Actually, I was going to say that the driveshafts stick do to lack of, or poor maintenance - not excessive maintenance. Most of the stuck shafts I've seen have been rusted into place - not twisted. A well-meaning but poorly informed shade-tree may not add a dab of grease to the top of the driveshaft splines prior to reassembly, or the o-ring may rot away, thus allowing moisture to get into the crank splines and rust up. Particularly bad on older Mercs that had both carbon steel driveshafts and crankshafts. At least OMCs have used stainless shafts since the 1940s... Merc didn't figure that one out until the 1970s.<br /><br />I've had some success by sacrificing the mid-section and cutting the driveshaft at the powerhead. You can then drill out the shaft from the crank and pull the splines out in pieces. Doesn't always work, but I've salvaged a few that way...<br /><br />- Scott
