There was an upgrade to the early Boat side socket that had a thermal breaker in it that would kick off, or eventually fail randomly. ABYC did not like that it came back on randomly. Smartplug will send you a retro fit kit with new boat side socket and plug innards to fix this issue at no charge (at least they did for me and a buddy after we experienced the random failures.)
After speaking with Terry (see post by SPS) I am all fixed up. Thanks all.
