sure no probs Dean - I got the light duty teleflex system from ebay item number 180102148667 - ive got it connected to an old yamaha 40hp and it does the job fine - feels strong enough and smooth moving. If you want it for a bigger engine you might want to go for item number 180102148667 which isnt that much more expensive but iam sure the light duty system would do you fine.
I actually made the mistake of ordering the wrong size of cable myself as it was my first time fitting out a rib with a centre console. I ordered a 12ft cable as I though id play safe and be able to bend the cable if needed but it turned out that I couldnt lose the excess unless I had it hanging over the edge of the tubes which I didnt want.
Anyway the company that I got it from on ebay were very helpful and replaced it no problem for a 10ft cable - all I had to pay for was the return postage. They also included a white steering wheel instead of a black one for me at no extra charge. I think theyve only got a few lengths of cable listed but if you email them they will supply any length you want and they also use a courier on a next day delivery basis - hope this helps
