I am running the aeromarine couplers on both boats and I am having a problem with them releasing the flex cables. On my sons boat I have to tap a few times on the coupler for it to release the cable. On my boat I have to hit the coupler many times with the wrench before it releases the cable. I have treid everything with the coupler with no luck. Any ideas or anyone know what company makes them so I can try and contact them. I have looked on the net with no luck.These are supposed to be the best but if they do not release the cables then I have to try different couplers.
