Need drop receiver and receiver extension

Thank you, Ron - really appreciate the heads-up. I've heard and read some real horror stories. My service tech warned me about backing even an inch. Regarding the power cable, I'm toying with the idea of splicing about 6 inches into the middle of it.
I've had boats for 30 years and there was always something to keep me busy. This is really no difference, except you can't sink!
