Hello, I am in the process of replacing my upper gear set on my 90's Bravo 1. I seized the original gear in fwd so I found a good deal on a new/used set. It came with whole assembly, 2 gears, clutch cone, pinion, etc. so my question is on my old set the timing marks has a line with a + - next to the mark but on the new set one side has a line with - mark and other side of cone has a +H marked. can anyone tell me what this means? is there a difference? also the pinion gear would not fit on my input u shaft the splined hole is bigger than my original one. so had to use my original pinion gear. when I go to line up the timing marks its hard to get them perfectly aligned I tried both ways 180 degrease back and forth it seems better one way than the other so went with it. looks like either top or bottom gear can use a half of tooth to line up perfectly. how critical is this if the lines are within an 1/8 or so of each other. Will this be ok? And can anyone tell me what the pinion gear is off of with the bigger hole? did they change shaft size in later years? thanks

There where changes in the gears in the early Bravo housing gear set. In order to figure this out were going to need the serial number of the drive. If that is not available going to need to look at the housing and look for a circle stamp and a number near it. There was also two different shift shafts used and gears are not interchangeable.

Serial number 0D764579 and below use one set, and 0D764580 thru 0F886005 use another set

The marks must align for the gears to be timed correctly, and my guess is the gear set you have won't work.
