So I had this idea... (grab a beer...this is a good one)...
Conventional single cable push/pull systems suck because there's alot of slop in 'em.
Calgo setups solve the slop problem, but I've read about a couple cables breaking. Cables are a wear item, and when they're in a sheath (like the calgo)..it makes it tough to inspect 'em. Plus, calgo systems are $$$
My idea is this:
I have a few old pump shafts that'll make perfect steering columns...put a flange mounted bearing on the backside of the dash and another one on the bulkhead, run the shaft between the 2 bearings and attach the steering hub to the part sticking out of the dash.
instead of the bicycle chain setup like the V-drives use, instead I'll use a drum on the shaft with about 5 or 6 wraps of cable...Run the ends of the cable threw a set of pulleys on the stringers up front, down the stringers, threw a set of pulleys on the stringers near the transom, then another set of pulleys on the transom next to/above the pump, and then out the transom through 2 holes and connect to the tiller arm. The cables though-hulls would be sealed with rubber bellows.
There would be a turnbuckle on each side cable end to adjust alignment and to adjust for cable stretch. The cables are 100% exposed for easy inspection. There are no sheaths to trap water and hide damage. I can make the system with stuff I've got in the garage...except the bearings. Cables will be stainless.
Any problems with this idea?
