Re: [Electric Boats] 1.5:1 drivetrain help

 

Sea EV exists as EV Machine Shop in Nevada. They developed and assembled
what is now the SolidNav unit. I believe they sold and relinquished all
rights to the unit, but remain doing machine work.

I believe Sea EV is SolidNav now. I don't think they sell parts but you
can try them; www.solidnav.com
