I'm not a tech head like some here. I have rebuilt about 10 of these gearboxes and fill them all the way with red Marine grease. Only been a couple years. Too soon to tell.

will check back in 25.

The original grease is Bentonite-based. It eventually dries up and shrinks.
Bentonite grease advantages
  • High-temperature resistance.
  • Non melting.
  • Good sealing properties.
  • Softening resistance.
  • Maintenance decrease.
  • Non leaking.
Are you advocating to keep using Bentonite, or to switch to marine grease?

And if switching to marine grease, would you clean out the old Bentonite first? (On a machine with 10 winters of homeowner use, albeit with heavy snow?)

Thanks.

I'm told that cleaning out the original grease is a best-practice, especially if you're looking for damaged parts. Since Bentonite grease necessarily doesn't play well with others, if you have the gearbox open I would certainly clean it out.
Here's what they often look like:

You can buy a Honda gasket online for between $11 and $15 or if you are in a hurry and have some gasket material, you can make your own.
This gasket is for a HS50 but you can get the idea.

This gasket below is for an HS828 but I think all HSXXX right-side transmissions use the same gasket.

Thanks.

I do hear an occasional, intermittent squeal/screech noise sometimes when the machine is moving. Haven't pinpointed the source.

Does that sound like something that could be caused by dry parts inside the right-side transmission?
