Using what you have to hand to gain some height under the boat to get at the keel bolt holes and dry fitting the first part of the rebuilding of the transom of the speedboat

Using what you have to hand to gain height to get to the keel bolt holes easier and gaining height to make sure the keel bolts will come out below the boat without digging a hole in the ground  

Gained about 6 inches of height which should be enough to do the job

Dry fitting the first part of the transom rebuilding just got to mix up some epoxy to glue it to new part to the original transom
