I just ordered the replacement kit for my 16' angler and it had a 15' cable in it. There was a number on my cable that had a "180" in it which appears to be the cable length in inches. So you might be able to get the cable length that way (or remove it and measure it). Otherwise it is just a Teleflex NFB Safe-T II System that is supposed to be a drop in replacement. I'm supposed to get it Thursday from West Marine so I will find out then if it actually does just bolt in.
