You could try the oven cleaner trick but its not going to just fall off. I would drop them at a place that does powder coating and have them strip it. The guy I use would only charge around 50-75 bucks to just strip them and I don't think you could do it any other way in less than 2 hours in any easy way. For me that's one of those things that I can do but make more money in the same amount of time doing what I like.

Go to true value and get good paint remover. Pop's is a good one.

Since it is marine paint and has been hot & cold it is seasoned really good.

fastest way would be to set the boat on fire....

remove all sensors,,get a gallon of tail strip and apply it to all the blue paint.wait until you see it bubbl,,about 20 min or so and pressure wash it off,,i did this at the local car wash once to a yellow car,,boy was the owner of the carwash pissed! i got yellow paint everwhere,,ill never do that again..

You could try the stuff called aircraft stripper it's available at most auto stores. It's nasty stuff wear gloves and it will still feel like your hands are burning through the gloves. It took the Factory paint off my motorcycle rims and gas tank. Lay it on think and you can watch it "kick" in about 5 mins litterally popping the paint off the metal. That or sandblast them.

As Livefree mentioned, aircraft stripper works pretty good. If you are careful, you can get the SS plates off of the covers in one piece. Don't damage them because they are worth their weight in gold. As he also mentioned, you can have them sand blasted. The stripper will get it all off, but it will take some time. Put it on and walk away. You may have to apply it several times. Work it in with a paint brush. You may also use a small wire brush to help it along. It may take 3-4 applications and a few hours to get it all off. Once it's all off, rinse it really good with the hose.

If you just going to bc/cc them just sand and scuff them up. If they are not corroded there is no need to strip them just to paint them.

Have it blasted if you have to strip it. Chemical strippers are a pain in the ass and thanks to the EPA they don't work like they used to. Oven cleaner won't even make it bubble, waste of time and $.

If you decide the stripper route is your only option , load it up with stripper and place in large thick trash bag and seal with tie wrap , as the fumes are needed in paint removal .
When removed wash off with water . I then proceed to blast with alum oxide then powercoat or epoxy primer and urethane . If you want the stock merc racing blue that is most likely base /clear .

Had all the blue parts on a pair of HP500's blasted last year and repainted with merc racing blue and they look new. four valve covers-two intakes- both alternators- and all the pulleys. Got the paint from ppg and the primer. Had a friend paint everything in his garage. The paint was 105.00 a quart, you can also get it in spray cans for about 25.00 a can but make sure u use the right primer. Teague marine has the spray cans.
