Lots of great info here. Great suggestion on not pulling too many amps on the wires. I knew to turn all power off before shutting unit down, I usually let it run for a while at the dock ( as I do with my outboards) to let them " cool themselves down" before shutting them off. I didn't know if there was a real reason to do this, now I know there is.
By the way, I have called FP with questions, ( maintenance, impeller, etc) they are very helpful.
