Abl,
I forgot you have an I/O. You may be able to keep using it. On an outboard I would defnitely repalce though, too much torque on that old cable. With power assist you might be allright. Just know that when it breaks it the whole system. I Think KeiKaffer and Mercury marine were part of the same some years ago. They make the big K-planes trim tabs you see on go fast boats.
