Re: removal of 1985 lower unit
Check this out. It may be of some help. Different motor though.
Welcome to iboats.
A manual is always a great investment.
^^^^^^^^I think you forgot the link???

There are a ton of vids on you-tube.
Basiclly you drain the oil, shift into forward, tilt up the motor and remove the bolts, giggle the lower unit and it will some loose. remove the bolts on the pump, iinstall a new one and put it back together. Takes less than an hour.
That is assuming that is why you are taking it off in the first place.
Read the manual, watch a few different vids, and Get-R-Done.
