I have heard that, but feared the mess. felt that the prybar knife and razor blade would be more manageable. I ended up removing the pluming but still had the drain tube in place which was a pain to remove foam around, but got it done.
there's a little more to go on it, then clean it up and prep for glass work.
drain side cut back, need to ensure solid seal and glass the tube in, as well as reinforce the cut back.
exhaust side cut back, need to reinforce and finish up.
if you look close at the lower hull side at the bond line area, there is a crack that runs nearly the entire length of the tray. This was a result of my brother running into me some years back. I had it repaired from the outside, but now that i'm in the tray i'll clean it up and glass it over.
overall tray, just a pile of crap in the corner. almost done
I play to put a layer or 2 around the pump cavity, i see a small visual crack on the left (port) side of the pump on the inside of the tray. so for added security i'll lay some glass down. I also plan to fill the bond line and reinforce the hull here in the tray as well, again need to reinforce the cut backs done to the rear. lots of things happening, could be a fun week.
