Yet another use for Marvel Mystery Oil! On my Boston Whaler we have a push-pull steering, Teleflex I think. It was getting hard to steer so I installed a device sold by Davis (the plastic sextant folks). I looks like a large nut with a hole drilled in the side. I use 90w gear oil rather than Davis' expensive magic stuff. Point being that after lubing the cable with gear oil, it works good as new. I put a couple of drops in about once a year. I think the gadget shown in the photo from the houseboatingworld site would be an easy solution. If you installed it at the top you could probably do without the air compressor. Gravity is our friend! Regards, Randy Pickelmann MORNING STAR
