I have the relay switch on my set up and I'd forget to set it to the on position. But you can learn to get past that problem after a few times swimming to retrieve you boat.
Glad you making the step up on the TM. I will have that to deal with that some day. I want a new boat so bad but I got to wait a while longer. I know you will love it. I'll look at it from a distance because you know me.
