Replacing the bilge pump sensor on a 2004, hull 1006

Total time: (1.5 to 2 hours depending on your comfort level with marine electrical systems)

My dock neighbors were reporting that my bilge pump was not shutting off after engaging.   After several calls it became aparent that my sensor was getting stuck, even after an attempt to clean it up.

Here is a quick overview on this very *easy* repair, and you do NOT need to drill any more holes in your bilge!!!!!

Tools and material required:

• Long and thin(er) phillips head screw driver.
• Wire cutter
• Wire crimping tool
• 2 Waterproof solderless butt connectors, 14 awg
• Heat source (I used an aim and flame)
• JOHNSON ULTIMA BILGE SWITCH   Defender P/N 502961
• 1 Waterproof fuse, 14 awg (I got mine from West Marine, rubber yellow, with crimp connections.)
• Fuse, 10 amp
• Volt Ohm meter

We recently experienced an accidental, but not particularly violent, jibe on Silver Lining, a model 2000 Catalina 320. 

Surprisingly, the traveler shackle fractured in 2 places.
