HELP-Evin. mod 6302s 6hp impeller problem

[bookfuzz]

I’ve just started working on 3 Evinrude 6 hp outboards and am trying to drop the lower unit to change the impeller on the first one.
A 6302s 1974 I think.
Should be easy enough but for some reason the unit will not separate more than a scant 1/2 inch. Hardly enough to fit a full sized screw driver in let alone a socket.
Don’t want to put to much pressure on it and mess up the works.
Worried about the other 2 if this is going to be the norm.

Any tips or tricks on this one. Cant get even close to loosening the shift rod screw at this rate.

Don’t like the engineering on these at all.

You need to turn the flywheel while putting just a little bit of pressure on the lower. There is a roll pin that holds the crankshaft seal to the drive shaft, and a slot on the leg that needs to line up with it.

try this site Leroy’s
put it reverse to drop the gearcase another 3/4 inch

read section on 6hp dropping the gearcase

thanks very much.
I did sort of try that but I’ll be a little more deliberate.

OK
Totally Peeeed off right now.
Rotated the flywheel back and forth till the cows came home and never had it drop.
Tried turning the prop to do it from the other end and no good.
Other than a 12 gage… any other advice?

1- look at picture…
a- lower brass cup under the carbon seal assembly rides above the drive shaft cross pin in the other picture

b – the crosss pin MUST line up with the slots to pull down the drive shaft

c- assuming the two are line up for an exit the splines may me stuck so wacking the gearcase down with a rubber mallet should help you get
enough room to take out the lower link bolt
d- a few more wack should do it

you could try to turn the motor upside side and have some release agent slide down the drive shaft and hopefully find its way to the shaft splines
way a day or two and retry

if all else fails pull the powerhead… not a big job anyway
