Minky

This is an old thread but after my recent experience I though I would provide what I learned - I purchased a used 2013 tracker with a 115 Mercury a couple of years ago and the water pressure gauge never worked. Last week I decided to fix it so I disconnected the 5/32 od - 3/32 id hose from the gauge and motor which I discovered was blocked and I could not clear it with a stiff wire - the gauge was good. My best fix was to purchase a 32' similar hose and a package of 12 "Pneumatic Quick Adapter Tubing Fittings" for around $20. I cut the tube from the motor to the back of the boat and verified it was clear. I did the same to the tube at another access point on the side and verified it was clear to the gauge and spliced in the new tube using about 10 ' of new hose. I cut the old hose in pieces to determine the cause of the blockage. It was blocked in two places which happened to be low places in the way the old tube was routed. My gauge is working now.
