powerwashing paint remover

I am attempting to remove original bottom paint on a 1987 Newport and return it to it's original gel. To the best of my knowledge the bottom was painted with bottom paint when the boat was new ('87) and a coat of paint was added 9+ yrs ago but not a bottom paint. The boat is always on the trailer and never left in the water. I have read most postings re peel away etc. Has anyone had any experience powerwashing off a paint remover after it bubbles up? Would it work ? I have a 2200 PSI washer w/15 deg or 40 deg nozzle (area would be secured to trap droppings). I tried a liquid varnish remover varnish on the transom and it worked pretty well after lots of rubbing and did not appear to have any ill effects on the original gel coat. Would a conventional paint remover work better/faster without hurting the gel? I know the bottom paint issue has been covered but I didn't see or may have missed anything posted regarding a power washer assisting the process. I may be totally off base. Thanks for your responses

It was sadly reported in these forums that use of strong power washing to clean the hull resulted in the appearance of osmotic blistering shortly afterwards. Apparently the force of the power wash drove water into the gelcoat and laminate!
Use caution if using power wash equipment would be my advice. And read this thread:

Although I agree to be careful, I can not see how powerwashing could permeate a gelcoat. I powerwash my boats, my friends do it, marinas do it. I have seen them permeate skin but not fiberglass.
