Steve,
I still have a lot to learn about the Vesc. But I can see it will be great
for analysing how the motor runs under load in various scenarios
like in air, in oil, in the thruster housing in air, in the thruster housing 
in oil & with differing temperatures in the surrounding water. ( kitchen sink)
Am away at the moment but are looking forward to testing when I return.

>>> Hi Guys, I just contacted my guy to purchase my last 4 Minnkota 101 trusters. For those that may be considering the 101 series, it will be soon replaced with the 112 series. According to my guy, who services electric motors, says he will be now having more business as the new series has  substantially weaker seals and that the new motor is also larger in diameter and needs 60A breakers. Not good news for us submariners.
