I've sold the twin 150's and the new owner installed them on his rig (long story). He had twin evinrude 115's so he was able to use his harnesses and cables. When he shifts the port motor into forward, it goes in reverse and vice versa. The starboard motor shifts into gear but suddenly dies. The motors worked fine on my rig when i demonstrated them. Could this be a rigging/cable adjustment issue? Thanks for your help.
