Brush and belt replacement hassles are overrated: I’ve been running now with the same brushes since 2002 or so. It’ll likely last another 6 or 8 years before needing the 2nd or 3 sets I have.
Re. 12v: 36-12v DC-DC converter---not expensive yet efficient---good for 300watts or so in my case.

Subject: [Electric Boats] Electric drive units
Hi members,
I am new to this group and intereseted in your experiences with electric drives for sail boats. There are several suppliers capable of providing complete inboard packages for up to 48VDC or even up to 72V.
I have checked SolidNav, Electric Yacht, Advanced Marine, Propulsion Marine and ASMO.
I would prefer a "maintenence free" system, i.e no brushes or belts to replace. Please correct me if I am wrong but it seems that Advanced Marine can offer that. Has anyone used such a system?
How did you solve the need for 12VDC for the rest of the boat?
Did you tap that circuitry into one of the series connected 12V drive batteries?
Any comments to this would be appreciated?
Gunnar
