Hey Jim,
I removed my Atomic 4 last year. I have a 27ft Cheoy Lee and am on Lake Erie. You're welcome to take a peek at my setup.

Subject: [Electric Boats] Need Help: 26'sailboat Mars PMAC replacing Atomic 4
I am considering repowering (Atomic 4) my 26' 6000lbs sailboat with a Mars PMAC. I will be using the boat for costal cruising on Lake Erie, the need for power would be getting in and out of the docks. I am thinking a Mars PMAC with 250A Sevcon programable regen controller, 2 banks of 3 batteries running at 36 volts. using a direct drive and the 50volt/rpn constant that would max out at 1800 RPM.
Even though I have a good understanding of electrics and a basic understanding of electronics, I have an above average mechanical ability as I have repaired everything from cars to hospital ventilators.
Questions:
Will a 36 volt system work?
Do I need a gear reduction?
What are the advantages of timing belt over chain?
Does anybody make a motor mount that costs less than $4000?
What am I missing?
Thanks for your help
jim
