They freeze...water gets in there and they freeze. Ya gotta be careful with them thats for sure.
Pull the pump, it will be really hard to reach the plastic nut that holds the steering cable. It maybe doable with just the nozzle out.
Take the swivel off the end of the cable, then the rubber seal things, then take that plastic nut thing out and pull the cable towards you. Theres two half plastic parts behind the plastic nut you just removed....take them off and slide the seal behind it off the cable. The pump end is now disassembled and will allow you to pull the cable into the hull.
On the handlebar end just get your head in there and look...3 10mm bolts and that end is out. Then slide the cable out, and reverse on reassembly.
I do have a few used ones in stock if you are interested.
