So I took the 83 Galaxie with 3.0 OMC sterndrive to the shop,now mind you I had it on the lake for about 5 hours, but combination of dirty fuel,old fuel whatever, took it to shop to get the carb rebuilt and to get it running again. The guy rebuilds the carb and now the boat wont run, says the compression checks as follows #1 150,#2 40,#3 40 and # 4 150. Says that either head gasket or bad valves is culprit,says the boats not worth the repairs and to come and get it. SO I guess my ? is what on and 83 Galaxie 3.0 with OMC Stringer is worth selling or should I just sink the whole damn thing?
