I'm about to start reassembly of my 1500. I picked up a set of mercury ring compressors. I have a 1973 Mercury service manual. I must say that the Mercury service manual was probably written by the same people that write Chiltons manuals. "Take engine apart. Put engine back together". It sucks. Anyway is there a good write up somewhere on how to use those 3 ring compressors to assemble a 6 cylinder engine or am I actually supposed to have 6 clamps?
