Good choice on TruCourse Steering, Andy! You're gonna love it!

I've been proclaiming the benefits of TruCourse ever since I did my
Buick-to-Chevy re-power retrofit.
If you locate all the required parts and proper length cable is safer,
more reliable and adds precise control and tracking.

For those who aren't familiar, with TruCourse, OMC oddly never offered
it on EJO boats. It became very popular with OEM boat manufacturers in
the 70's that were installing the OMC Stringers. It is a torque-free
design, also an OMC proprietary design consisting of gear-driven, sealed
push-pull cables. As an added bonus, (in my case) I got the nifty
rudder-angle indicator.

The other steering option (beyond EJO's inexpensive and lightweight
rope/pulley/cable system) was the single (large) cable mechanical system
(based I think on Mercury's original Ride-Guide, later sold to
Teleflex?). These were often used in twin stringer installs and require
the "tiller" arm to penetrate the transom and attach directly to the
sterndrives' external down-leg, thus defeating the stringer's elegant
single-hole-thru-the-transom design. But they did use industry-standard
parts, so the OEM boat builders like them.

I just bought a tru course cable set up and am replacing the old cable
system with it on my Tiderider...

Much easier to maintain as well!
