1978 Johnson 70 HP Seahorse 70EL78C - I believe that is the serial number or part of it. Just a quick rundown, was my old boat at one time. One cylinder was getting water into it. Had head gasket changed, still same problem. He took it apart this past weekend and put it back together and resealed everything. Ran for 20 mins and said no water was found. He's that by resealing it, it stopped. He needs to know the tourq specs and sequence on the bolts for the heads. Does anyone have this information in pdf format or could scan a copy for me? I might be going to far, but what about a manual in pdf? Any help would be greatly appreciated.
