Hello, <br /><br /> First Post so go easy one me please. To make sense of what I'm about to say let me start from the beginning. A month ago our friends who own Silverthorne resort @ Shasta Lake were selling their chase boat. Its a 1981 Bay liner 18'8" w/ Volvo 4 cyl. overhead cam in superb condition more or less for $1,000+newer trailer. (trailer is worth 1,300 that it came on) however the reason they were selling it is a valve had burnt up (popping in intake manifold and low compression in #4 cylinder) so I'm going to need a valve job. Anyone know how much this is going to cost?<br /><br />But for my main question is I went to replace the bellows and lines because they were all rotted out. I got a selco manual but they arent very specific on any the removal of the stern drive which I need to remove to replace the U-joint bellow. I got the two Allen screws in the steering helmet off but I cant remove that blasted spacer. Help!! I also need help on how to remove the 2 screws/bolts that the outdrive pivots on. Do they Screw, push, or pull out? (Yes I removed the Allen screws holding them in place.)<br /><br /><br />If you cant tell its my first boat and I need help!!
