Iota doesn't make a 36 volt converter anymore but it's no big loss since they never made one big enough to keep up with a 101. Buy [3] 12 volt converters and hook one to each battery.

 

Do exactly what OBG says!! I put three of the DLS-45s on mine and it makes me a little more tollerant of the troller boat. LOL Honestly it does great, I can run all night long as fast as I want and I havent charged my batteries since I bought them, other than what they get when your runnin. I will fore warn you to make sure you got enough generator. I would allow 2000 watts to cover the converters.
