Default Galvanic corrosion

John, the snaps were installed at the factory to support the standup boat cover that you would use while underway.
This cover came as standard equipment with this boat.
I did order the optional stem to stern custom fit travel and summer storage cover because Legend claimed you could trailer it down the highway installed on the boat.

How are all of Legend's claims working out for you?
Show me where Legend claims you can travel down the highway with the
storage cover installed.

OK, but I'd still remove the snaps and fill the holes. I'd never trailer a boat down the highway
with the cover on regardless of the manufacturer's claims.

Why not? I trailed a 24 foot runabout from Connecticut to Florida
with the cover on and with no damage. We were running at interstate
highway speeds of 70+ most of the way.

Depends on the cover. I have towed my boat thousands of miles in 20 years,
with a snap on trailer cover. Top Gun material, and am on the 2nd cover
since the boat was new in 1991. Just towed 500 miles round trip to Shelter
Cove, CA last weekend. Great fishing. Lots of Rock Cod,mbyte only one
under sized salmon.

My new boat started to develop blisters under the gunnel paint where the cover snaps are attached.
After the 2nd season of use, I brought this to the attention of the dealer and Legend boats up in Ontario.
This was last October and the manufacturer still hasn't come up with a plan to remedy the problem.
I did the usual Google research and sent the links to the service manager at my dealer.

Guy at Legend said he didn't want to talk directly with me and problem should be handled through dealer.
They also wanted me to tow the boat back to the dealer ( 180 miles round trip ) so techs could check for stray current, which I did while down anyway for winter servicing. No stray current from my motor.
They also suggested that it could be a stray current problem at the docks I frequent or stray current at local, marinas.
I explained that most of the small boat launches I use have no electrical services and anyway, I'm only there long enough to get my trailer and retrieve the boat.
Anyway I just contacted the General Manager of the dealership (member of family who owns the business) who acted as my salesman two years ago when I showed up while the sales staff were away at a boat show.
He says he will look into problem.

From what I read, we have to remove the snaps that screw directly into the painted aluminum gunnel, sand, prime and paint affected areas.
Then we have to find a suitable gasket or washer to isolate the snap and the aluminum and even coat the shafts of the attaching screw with liquid electrical tape or silicone to isolate them as possible.

My question is, can those self tapping screws be backed out of the aluminum and then be re-installed?
I broke two bits trying with a hand screwdriver last fall, so I google up higher rated impact type bits like the Makita Gold
That should hold up in my corded drill/driver.
Anyone ever attempt this.

Are these stainless or are they chrome over brass?
(scratch one and see)

Brass and aluminum are a battery and they will blow holes in the
aluminum in the presence of an electrolyte like salt water

Manufacturers do seem to get away with it on a fresh water only boat.

Stainless is better but still not totally immune.
If you use stainless, put some TefGel between them and use only 316
stainless parts.

Here's one chart. The closer there are, the better they work with each
other:

Stainless looks a lot worse on that chart than reality.
My boat is bolded together with stainless fasteners, it gets dunked in
warm salt water about 100 days a year for the last 40 years and I am
not really seeing that much trouble.

Could be that your boat isn't made of cheap aluminum designed for fresh
water use only.

I still wonder if those "stainless" snaps are not actually chrome over
brass. Stainless corrosion on aluminum would be a white powder.

Again, look into "TefGel" that is what the bimini top installers use
when they put stainless screws on aluminum pontoon boat rails.
It creates that barrier you need.

I see FlaJim is still the same insulting asshole he's always been. Must
be tough stuck in the 7th grade as long as he's been there.
