Bottom Removal

With the boat on the dollies, we began removing the putty from the bottom for removal of the planks.


The putty was drilled out using a modified a 5/16” wood spade bit.  The bit removes the putty to the screw top and, most of the time, the small tip would find the slot of the slotted screws.


For the few screws forward, above the waterline, the factory installed wood bungs.  We used a scribe to split the bung and pop the bung free.  With all of the screws exposed it’s time for the screw gun.  Most of the screws came out easy, except for the few broken or striped ones.


At some point, a previous owner installed 5200 rubber in the gaps between planks in an attempt to slow leaking.  This is not a good idea on original planking because with each swelling cycle the plank no longer has room to move and pushes the chines out of the frame landings and can cause the planks to cup.  The planks came off easy after cutting the 5200 in the gaps and a little prying at the striped or broken screw locations.


Several hours later, we have a lot of brass screws to recycle.
