1993 Prop shaft seal replacement

[456eec]

I have a 1993 25hp Johnson J25RETS.
On Sunday I went fishing. As I went to launch the boat I noticed green gear oil leaking from behind the prop. I've had the motor from new and have never replaced this seal. I notice on the schematic that you seem to use 2 seals back to back.

I'll order the seals but could someone give me a step by step on how to replace them.

Regards

You will need to remove the bearing carrier (#1) and press them out from the other side. Becareful not so damage the housing.
