How much short is it? ,,,,,
Possible solution is this, I was going to use it on my aerotec for when I got a second hand steering set up (about 4 years ago) and the cable was short,,, think it was 8'. But end up finding a 10' cable in the end.
So instead of the cable having to meet up with the tilt tube, it fixes to this and I'm guessing will be about 8/10" away from your engine.
Means fixing it to your transom, comes with all the stainless fittings.
If you think it will do,,,, will send up FOC.
