Another datapoint:
· ETEK brush motor installed into cowling of 25HP Tohatsu outboard in 2003 on 26ft barge cruiser “The Reach Of Tide”
· Now going on 8 years with the first set of brushes (probably 100hrs/yr runtime at 1500RPM average)
· Inspected brushes and commutator last summer (after 7yrs) and found commutator looks good and brushes probably 50% worn
· Likely the first set of brushes can be used until 12yrs have passed, then I have 2 spare sets of brushes---probably good for another 25yrs.
If you can protect your motor half as well from moisture as mine in its outboard cowling, brush- or brushless, you’re fine, IMO. Caveat: Provide air sufficient to remove graphite brush dust, and even then, clean it out after a few years. OTOH, I’m sure in a salt spray environment, a better choice can be found.

Thanks Don, I suspected that.
