Is this the cause of electrolysis
Submitted by Paul200990 on Mon, 2019-12-09 13:55
hey guys,
after doing slme reading and getting paranoid now im
curious if these spots on the bottom of the hull is a cause of electrolysis. I bought this boat after it was sitting in someone’s backyard for around 6 years and had this in there where I bought it. Help would be great also how do I remove it too :)

Looks more like tiny stone chip damage
Does the pitting reduce as you head further back on the hull if so this would pretty much confirm that conclusion.

Nah it’s literally all over
Nah it’s literally all over the bottom of the hull. I thought it was just salt crystal build ups nah nah. Might get some salt away on it and see if that works. But it’s not localised to one area

Causes holes to be eaten thru the hull.you probably need marineline or someone to check it out.

Yeah I understand what
Yeah I understand what electrolysis is but thought it was only segregated to “normally” a single area on plate hills not spread all the way through.

run you fingernail over it
run you fingernail over it if you get a small amout of "white rust" (looks and feels like a salt build up) then it is electrolysis.
areas like in your pic are usually only formed when the boat has a stray current IE some wiring is faulty and has earthed to the frame. Multimeter time.
do you have a SS prop ? if so is it getting pitted?

Yeah stainless steel. It’s a brand new engine on it so can’t tell atm. Bought the hull second hand so possible did ages ago def doesn’t anymkre though

usually the SS prop is the first to show a stray current. will turn white in a day of boating. but if the current and wiring has been sorted you may need to just treat the affedted area. (google)
corrosion is caused by contamination with another metal (sinkers, iron fillings, etc), a build up of gunk (alge etc in the bilge) .....both of these localise to a specific area and of course start from the inside out. To combat this its a good idea to put some boatwash in the bilge at the ramp (bung in) put 20-50 l fresh water in and drive it home .....then rise at home. do this every now an then.
but if you have corrosion starting on the outside it's almost always stray current. (I guess.. was ...in your case)
