This is a gently used Mercathode Tester that will allow you to periodically check your outdrive while it is in the water to see if you are getting the proper readings necessary to protect the drive against Galvanic Corrosion. (TESTING THE OUTDRIVE WHILE THE BOAT IS IN THE WATER IS THE ONLY WAY TO KNOW IF YOUR MERCATHODE SYSTEM IS WORKING PROPERLY) I am selling it because I no longer have my boat.

I used this probe every month on my boat for the last several years and found it invaluable to ensure the Mercathode was working properly. It helped me identify a problem early on (twice) so I could get it fixed as well. Remember, even though you regularly change your anodes there is no guarantee that your Merchthiode System is working.

If you want more information on the tester, take a look at this web site. http://www.mercstuff.com/mercathodetest.htm

If you purchase this new you will pay anywhere from $110 to $130. I will sell this for $70 and I'll pay the shipping. It comes with the original box and the instructions. The tester looks like this. http://www.marineengine.com/newparts/part_details.php?pnum=MER91-76675T+1
(For some reason I cannot upload a picture from Photobucket to post here but if you are interested, PM me and I will email you a picture.)
