From the outside where they are exposed they look like fiberglass and look like they are fully glassed to the boat. (Not tabbed) I need to pull my interior out to get a good look at them though. Looking into them from the filler the appear to be metal on the inside.

No actual shit lol but there is something in there clogging up the filters.

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?!?!?

Good luck I tried to get a hold of him a bunch of times! I gave up and bought something else.

My insurance company wants to know the model of my 1979 crusader. All I know is it's 18ft and that's all the registration has on it. I got a bunch of different answers on a jet boat Facebook group including lie to them who cares, however I care and don't want it to bite me later. I figured this is probably the best place for advice and setup a account to find out. Let me know if you know 100% what model this is. Thanks!!!!
