Hi, has anyone done this? Just wondering how you get the old ones out etc. TIA. Peter.

Remove the prop

Undo the screws that hold the gearcase cap (That'll be a challenge to do without breaking them! )

Ease the cap out.. The O ring around it will make that difficult.

I think the seals will come out with the cap. If not they will be behind it and will be extractable by the usual methods.
Note two of them back to back.

You might find the engine is covered by a manual at http://boatinfo.no/lib/library.html#

Thanks Vic,Two bolts came out easily and cap too. I looked in the manual but they are using a special tool to get the old seals out. What do you mean by "the usual methods"? The seals remained in the cap by the way.
