While backing Cay of Sea into our slip with Ruth at the helm, she shifted into reverse and applied a good bit of throttle to change direction of the boat. Then while attempting to counterbalance the reverse thrust in forward, she moved the throttle forward after shifting gears, and nothing happened.
I instantly thought the fitting that holds the cable-end captive had let go, but on inspection found that the cable had broken at the throttle-lever end. I disconnected both ends and slipped it out of place to examine the break. That’s when the end of the inner cable came out of the outer jacket entirely.
You can see the threads and nut on the rod that attaches to the control lever. The other end has the single strand cable captured in it, sort of like a swage fitting. So my conclusion is that the steel strand that actually moves inside the jacket was allowed to work and flex right at the connection point to the threaded rod end. Eventually (last week) it became brittle and broke.
So I ordered another through Amazon: $23, and if you have have Amazon Prime there is no shipping charge (here’s the link: https://www.amazon.com/gp/product/B004LF7364/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1).
When I install it, I think I’ll try and capture the lever-end of the cable so that the strand doesn’t flex. Maybe I’ll get more than 10 years out of the next cable!
