Just pulled my 29' Luhrs for some bottom work. Had about 3 years on a good ablative paint job. Paint started to show through in a few places and had some barnacles on the hardware but not excessive. Now for the good part. The starboard engine water intake was heavy with barnacles, almost to the point of being stopped up but the port intake did not have a single barnacle on it????????? My guess is the bond came lose on it. I checked it over real good on the outside and it had no pitting or corrosion? It's a bronze fitting. Now the question. The intakes are only connected to the system by rubber hose. There is no electrical connection to the boat, other than bonding. Does the bonding make the marine growth grow more? If so would I be better not to bond the intakes? If they were not bonded would they deteriorate (the port intake didn't at all) eventually?
I'm goiing to put a meter on it tomorrow to see if the bond is indeed not connected. Just wondered if anyone else had ever seen this kind of problem. Thanks!!!
