I used Peel-Away for the majority of the paint, then wet sanded the rest off down to gel coat. From there I worked my way down with finer sand paper to a polishing compound using a 7" polisher. It turned out like new. This was on a 33 Hydra Sport I bought in St.Pete.
From the sound of yours it would be a piece of cake.
Be careful with a water blaster, a good one will take gel coat off.

If your pressure washer is taking it off, I suggest you just stick with that. I usually use my pressure washer for removing ablative bottom paint.

I don't see the original posting here from yesterday, but I think I saw where you saw/heard of a new clear product to put on the bottom that contained Teflon. I would be very suspicious about it. I just recently bought a new Tahoe and the dealer was trying to sell me a protective coating where they would use a thing called "Simoniz System 5". I wasn't sure, so I said no but I would let them know if I changed my mind overnight. I Googled it the next day, which you should do also, and found that it was a waste of time and money and really didn't do anything and in fact it actually harmed the finish if you had to have a repair made. They said in the Blogs that Teflon must be heated to some very high temperature before it would actualy adhere to any surface to have it last over time.
I'm not a chemist and I'm just passing on what they said, but I felt that I owed you this info.

From what I remember from yesterday, a scrub brush and some TSP will probably get rid of what is still left after power washing.

How much difficulty you will encounter in removing bottom paint depends on how well it was applied. If the hull surface was abraded and its glossy finish removed before the first coat of bottom paint was applied, removal will be difficult. If the hull surface was left intact with a smooth and glossy finish, removal of bottom paint will be easier but still labor intensive.

I went on their website and looked at the pictures and it looks like they put this stuff on top of the bottom paint. Is that true? If so, why are you taking it off?
Or did I miss something?

I'm about done with the bottom of my 1978 21 Revenge. It had two coats at least one hard and one ablative, both of which were gone in places. I tried the pressure washer but it was slow and did eat the gel coat up if you got to close. It was cooling to use in the summer heat, but I finally abandoned it since the damage was to hard to control. I went with a soy bean paste environmentally friendly remover that was like syrup. It worked pretty good and I'd put on a section in the evening and scrape it off in the morning. Damn hard, dirty work. It left a blue stain that I'm wet sanding off now. Still damn hard work even though I'm using a palm sander. I've dropped down to 180 grit after starting with 400, that is making it a little faster. Still I can only do about a yard square an hour because I'm sitting or laying under the boat which is on blocks. The bottom is nice based on my test wet sand, compound, polish and wax experiment, but there are a lot of little dings to fill with gel coat or marine tex and I'm not sure it will not look better to just repaint it with a hard paint since its going to stay on a trailer while I have it. I'll never buy a used boat with bottom paint again...to much damn work and trouble.

If you are on a trailer then you could drag it up to Hauppauge and have it soda blasted. I don't have the name of the shop handy but they usually advertise in the Fisherman.
