What O-rings are you using on the outdrives? Black or red?
What grease if any was applied to them? The black molly grease doesn't really work to well with the o-rings and causes them to swell and be tight. I'd suggest you replace the o-rings and use a touch of green slime o-ring grease on them instead, as it won't react.

Removing the shim is releasing some pressure off the swelled o-ring by the sounds of it, confirming what I think.

I did use green slime o-ring grease on it, only using a bit of the black grease on the relevant other components of the diff. shortening the shim as you say does sort the problem, do you think I'll have any shortfalls using this fix or do you think it'll be fine to use as is?

EDIT: I used the Black o-rings aswell, sorry, forgot to put that.

Thanks,
