Re: [Electric Boats] brush or brushless?

thanks for the infor Myles, I did buy an extra set of brushes, and apparently I have many years to go before I will need to dust them off and put them to use. Being inside my Ericson 27, my electric motor has never put it in jeopardy of having to deal with water

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.
