Daniel - Call Wema for a new sensor
I had my sensor fail (out of warrenty), also. You can order a replacement Wema sensor for your boat from Hunter or directly from Wema -- for the same price. I ordered from Wema as a wanted some dialog with the manufacurer to find out why the dang thing failed so quickly, Here is what I learned.If you haven't looked at on of theses sensors, they are a long cylindar, long enough to reach the depth of your tank. They are made of hard plastic. The outer shell of the cylindar has holes in it. Apparently, "stuff" clogsthe holes over time (too little TIME, IMHO) and causes the guage to give false readings or malfunction. Wema has added a nipple to the top of the sensing unit that allows you to hook a small hose up to it that will backflush the unit with water to flush out the "stuff" so that the unit will not clog. I purchased a new unit and the flushing kit. It took about an hour to unstall. I've had it in about a year with no problems. Installing the new sensing unit is a "humbling" experience. I agree with your point on guage failure. The failure rate on Hunter's OEM parts is too high, a point I have made many times on this forum. Mine failed on a new boat in the second year. My water tank sensor has failed as well, but I have decided I can live without a new one. There sensors aren't cheap!To be balanced and fair, I have discussed the high OEM failure rate with the guys in customer support. I get the impression from talking to them that they are definately concerned about the situation. I didn't sense it was "lip service." BUT, that conversation was over a year ago. OEM part failure rates should begin to improve OR one could then assume that we are getting "lip service" OR Hunter management is not willing to spend the extra money to buy quality parts. No one thought Ford and GM could build quality into their cars, either. But, it's obvious that they got religion on this subject. It took Japenese compition to move them to it, but they did fix the problem and so can Hunter. My next boat purchase will depend on how much progress I think they have made. That's my progative as a consumer. I hope this helps.Wynn FerrelS/V Tranquility
