Merc 25XS Gearcase Service

[TomSki]

I did have to ream the seats in the gearcase and cone out to .750" to accept the GB98 (or SCE98) bearings. Not sure what the original bearing was. They had no stampings to identify. The bearing supply house could not cross reference them with the given dimensions. Weird! At any rate, GB98's it...

Thanks to all the great help, I finally have my gearcase sorted out. As it turns out it is a good thing I took it apart. It didn't register right away, but when the prop shaft came out, the front needle bearing was on the shaft! It wasn't even pressed into its seat! No wonder it didn't feel(or sound)...

Will do Steve. Thanks very much. What is a good time for you?

Give me a call and I can talk you through the process and give you pointers.

Thanks for the barrage of replies. Laddies, I tend to agree with you. Without the lash specs though, I am afraid to assume they are good. There is a fair amount of axial play in the driveshaft which concerns me.
Does the pump housing pull out or thread out?

[TomSki]

Yes. Shipping and customs can be a little prickly at best. I would normally drive to upstate New york for shipping and receiving, but.......

[TomSki]

Lol. Should have mentioned that.. I'm in Ottawa, Ontario.

Hi all. I was checking out the gearcase for my 25 XS, and it needs some service. At very least seal replacement. Is there such thing as a service manual available for these? If not, who would be a good person to do the work for me? Preferably somewhat local.
cheers
