Nissan 3.5 leaking gear oil

[AdamH1991]

I bought a used Nissan 3.5 2 stroke and have a gear oil leak coming from the impeller housing. I have purchased a new oil seal but cannot find a way to remove the bearing which sits in front of it on the drive shaft. It appears that the bearing is pressed onto the drive shaft and also pressed in the water pump housing. Please help!

Need your actual model. Is this the one without reverse, that always starts in gear?

No reverse, only fwd and neutral.

Thanks for any help you can provide.

The bearing is pressed onto the driveshaft only. The housing is 2 pieces. The seal presses into the lower housing.

Thats what I thought. I just need to get the bearing out of the lower housing without destroying the shaft. Any tips for that?

I have had good luck with a vise set to clear the shaft and "popping" the shaft out.

Finally got back to working on this project. I was able to separate the bearing from the housing following your advice. Now, I see the pressed on bearing will need to be replaced. Is it possible to do this without any fancy tools? Thanks.

Not easy getting a new bearing in the exact right place.
