Starcraft Islander 2007 (Aluminum Boat). The paint around the rivits is popping below the water line. Starcraft says it is electrolysis & no warranty. Are there any ways to treat this problem. Any input is greatly appreciated. Thx much...silvrfoxm :mad:mad:

Ayuh,...... They're Right........

My 1974 did the same thing shortly after I painted it,........
When I removed some cockpit lighting that was grounded thru the hull,....
The Issue went away.......

Either You've got a Wiring Issue,....
Or,...
You're moored too close to somebody who Does........

Re: Starcraft popping paint below water line

The boat is left in the water from 5-15 to 10-15. It was a new boat. Bennett trim tabs were added, perko battery switch & Lowrance X96 . That is the only electrical items added that I know of that isn't factory. Any help with this problem will be greatly appreciated. The boat is in storage at the moment as it is winter here. I want to be ready for spring & I think this is a serious problem that needs attended to. The dealer only sold Starcraft for the 2007 season. I don't have any faith in his knowledge. Thx in advance for any help...silvrfoxm

Re: Starcraft popping paint below water line

Is anything on your boat grounded to the hull, as Bond-o says?

Or does everything go back to the battery through a ground wire, like a fiberglass boat?

If you don't have anything grounded to your hull then it could be an issue with someone else's grounding, again as Bond-o said.

I believe Mercury makes an attachment that you can measure the electrolysis in the water referenced to your boat.

Not real sure what you can do about it if it's caused by someone else's boat.

Re: Starcraft popping paint below water line

Since when does electrolosis cause paint not to stick? Sound llike BS to me there's many many aluminum boats out there without peeling paint problems, I've seen plenty of electrolosis from disimilar metals causing corrosion but not clean flaking off of paint, to me that looks like bad preparation prior to paint, I would take it right back to the dealer, c'mon less than 1 yr, if thats really the case like bondo says than I'll never but one of their boats, I'd be sick for sure if it was mine.

Re: Starcraft popping paint below water line

The pictures are not detailed enough, in my opinion, to make a determination. I am inclined to agree with electrolysis-for now.

A close examination would show signs of pitting in the metal, a sure sign of electrolysis.

If there is no pitting and only the paint top coat flaked off, then there is another issue.

Re: Starcraft popping paint below water line

Is the paint bubbling up, with white corrosion under the bubbles, or is it just flaking off?

Re: Starcraft popping paint below water line

It doesn't seem like the paint bubbled up as I didn't see any bubbles anywhere. I didn't know of the problem until the boat was taken out of the water for the winter in mid October. The marina cleaned the bottom for me & that is how I found out about the problem. The paint looks good on the smooth bottom, no popping or peeling. It is only popping at the rivits under the water line. Thx for any help in advance. silvrfoxm.

If the primer is not "popped" it is not electrolysis. You may also have rivets along the keel, how do they look?

I would ask (nicely) Starcraft to explain how it can be electrolysis if the primer is still intact.

Re: Starcraft popping paint below water line

Is electrolysis really the correct term here? Or is any of this galvanic corrosion?

That will get you nowhere-fast.

As a customer service rep.-myself, confrontation begets confrontation. That's human nature. I'm all for getting the issue resolved to all the parties satisfaction, rather than butting heads.

Let us know what you see, in the spring. Check the rivets along the keel and anywhere else below the waterline.​

Re: Starcraft popping paint below water line

Hey i've done it before. One time the bank messed up one of my debit/credit cards, they made a mistake when my wife changed her name after we got married. Well they admited to the mistake and said it was fixed. We were going on a trip out of state so we went into the bank before to make sure that everything was ok and they told us that it was fine. Well we use that easy-pass for tolls on the highway. That is linked right to our bank account. well about a week later the tickets started showing up in the mail from delaware and NJ because the easy-pass was not working so we didnt pay the tolls and we hat 5 tickets. The bank said since it was their mistake that they would pay for the tolls and what not but they could not pay for the tickets. Well they said that it was their mistake and told my wife and myself this and they would not pay the fines. So i got a sign and put on it "this bank owe's me $260 ask me how!". I stood there close to the entrance to the bank and told everyone that asked the story. About a half hour later my cell phone rings and its the bank telling me to bring the tickets in and they will cut a check. So it was done. They payed up like they should have done in the first place. Im just telling this story because this method worked for me. I dont know if it will work in this guy's case but i was so pissed with that bank and they were rude on top of it.

In refernce to post#17. Some of the rivets on the smoothe part of the bottom are popping. The rivets on the keel aren't popping, but there is some corrosion around a few that looks like dried plaster that can be scraped off with your fingernail. The boat had been cleaned by the marina & I don't how much corrosion was there before the cleaning.

It would be very interesting and informative to get a look at the back (inside) of several of the rivets that seem to be affected.

If it is electrolysis, it may affect both sides. For electrolysis to take place, you need a medium. In this case, it is water. When you get a chance, take a look at some of the rivets in the bilge. Especially those at the bottom of the transom. Those probably would have had water on both sides (inside and out).
