Just yesterday the RIO on the X758 quit working. (Thanks to a small piece of wire and a couple spade connectors)
The Nanny state is just too intrusive. On my Simplicity, there is a key on the dash, you turn it ONCE and the RIO is disabled for that cycle of the PTO being turned on. A little red light indicates that this feature is enabled. Pretty good compromise in my book.
A few times when pushing the RIO switch when reversing, the deck shut down anyway.
