This is what i use on my twin Force outboards.
Installed it 21yrs ago and had to replace only 1 seal(free)
They might sell these on this site.
My boats an 88 with twin Force 85's
The steering was rated for up to 5 or 600 hp(I think).
Post a pic of the front of your motors, where the steering goes through.
Also where the cable comes out of the transom.
It was a very easy install,just make sure to test it BEFORE you go to sea(I didn't).
My boat turned left when I wanted to turn right
