i think you have to disconnect the shift shaft on those years but beyond that if its never been off before or in several years it could be impossible to remove without damaging the crank - my buddy has seen many that the only optionis to cut the driveshaft in half and replace the crank and drive shaft . give it some time - you could also unbolt the block and try rocking back and forth .

You might find the manual need here. I don't know what year a brownband is. You probably need to disconnect the shift shaft.

Re: lower unit removal::i must be missing something

removeing the driveshaft wont work it will still be stuck to the crank and you wont be able to to slide the water pump off - dont worry your not the only guy who's been in this situation - try what i said . if you can hook up a pulley above the block and attach a rope or what ever to it then tighten up on it to give it some pulling pressure then undo the bolts on the block and wiggle the block front and back it might just seperate - thats how i did mine -although i left it over night with rope and pulley keeping pressure on it and it came off - i then lubed the shaft up real good - previous owner never had it apart and thats what happens -and why they recomend changeing the impellor each season ( impellors usually last a long time on motor that does short trips and trolls ) .but before all that you will need a manual and verify if your engine needs the shift shaft disconnected - even some engines of the same year are fitted with different style lower units so the only way to tell is look up your serial number and study pics of the lower unit .
