My mate picked up a 12ft. tinnie with a 20hp blueband wrap around cowl 15" tiller. the whole unit is in tip top condition except somehow mate went boating, first day out, without oil in tha box.
He got sold a gearbox from a red band, price was right, bloke said it would bolt up, Mate's happy until he puts it in reverse to back out and moves foreward an hits tha dock, puts it in foreward and backs out into tha river

Can tha shifting action be reversed in tha gearbox??

Since the gearbox is the only thing that got changed it would seem that there is a difference in tha box.

Any suggestions????? please?????
