And to go with Marinautics question what is the engine?
Depending on how much you can bend the exisiting cable you might be able to just undo the large nut on the end of the cable were it goes into the engine saddle. If not and you can't undo the steering wheel end and pull it through then its an engine off job to get the cable out. Nothing difficult, just have a couple of good friends around with some beers to help you hold the engine whilst the old cable comes out.
