Our conclusions concerning the Jaycar anti fouling system:
We installed FOUR units on our Beneteau
50, more than enough by all accounts.
And, after solving the fuse blowing issue (as reported in former posts here) we are VERY SORRY TO REPORT that we have come to the conclusion that they ARE NOT WORTH IT. Period.
Although upon inspection
we initially thought we saw some cleaner areas than usual, one being in the area where one of the transducers was installed, basically we have found no conclusive evidence of any improvement since using them other than a noticible increase in our shore power
How we hoped for something, ----anything(!) in the way of a good report. We would have been happy with even a MINIMAL improvement, but found none.
Your results may vary. (But I doubt it.)
For us, it was a complete waste of money
