Jim, If you are making a change in "current production" then I would like to send mine back and get a "current production" one with the problem cured. I'm a bit P.O.ed here in that there were no instructions with this thing on what to watch out for if in fact there are some issues in the installation. If George Beckman had not brought this entire thing up a couple of days ago I could have installed mine as is and LOST THE MOTOR. I would really appreciate a heads up on issues like this in the future.

Thanks,

Gary and Joanne Worobec
1973 Glacier 23
