final drive question

i just bought a 1990 maxum with a 3.0l 130 hp. got a mercruiser alpha 1 with a 1:98r...serial number is 0c827796(believe this is a gen 1???) the upper part of the outdrive is bad. the "pinion and carrier" gears are stripped out. the lower unit feels smooth and engages to reverse and forward. are the upper units are geared the same? like for a 1:84 final drive upper unit the same as a 1:94??? would a 1:84 final drive work is this boat or would i be giving myselft problems???? got anything laying around? need one...
