From the description of seeing bubbles at the case joint, it should just need a reseal job. While you have the case open, also be sure to change the upper and lower crankshaft seals. I don’t have a parts list for that year model but I believe it uses a carbon seal with an internal O-ring for the crankcase seals, similar to later model QD motors. Just need to replace those O-rings.
