I put on a Trac aluminum motor bracket and a Trac mounting plate to be used with a Torquedo travel electric motor. That way I can get in and out of boat launches and not hold up all the bass boats. The cracked easily disconnects, leaving only the mounting plate.
I've also been thinking about doing the EC as a Class 6, electric and experimental, and sailing from the finish to the start and then back, using g a solar charger and doing it as a cruise rather than going 24 hours. Just a thought - if I sit very still, maybe it will go away.
