2001 Sv2100cc t top install

[brad68]

I’m brand new to glass boats and I’m currently putting a fish master t top on my sv21’. My question is this…..I was drilling the holes near the rear of the cc and pulled back some gray dust and was resistant when the drill bit hit it. Not drilling very deep at all but not knowing ANYTHING about what’s under the deck has me concerned I have possibly hit something that I shouldn’t have. Can anyone offer me any insight on this issue? It’s just to the left of the rear left corner of the console.

Thanks!

Brad

pretty sure a 2001 should have a poly tank my 2002 does anyways

also the tank should be an inch or two under the glass i think. I know when you open access panel below leaning post tank is about  1.5 to 2 inch under the deck
