I'm looking for some advice from the group, I just got my boat and it started cutting out on me when getting on it. I later found green flaky crap clogged up my filters pretty quick. I cleaned out the filters a few times but it keeps coming. This trip I tried putting sea foam file treatment which may have broken some of the stuff up because now the fuel turned merky green running through the filters.

I looked at my tanks and the look like the original ones which are glassed into the hull, any recommendations on how to clean out these tanks with out cutting them out?!?!?
