Started out as a engine bay rear bilge redo on my 99 246 that went as planned. Thought I had some standard glass work as I had 3 hatches to redo and one engine mount that needed a small repair. Unfortunately I have now discovered the wood that runs under the gunnels is mush. I have removed the glass exposing the rot from the underside starting up front. Does anyone know how far back the plywood runs. I am at the rear rod holder. I just hope that I do not need to go as far as the rear gas fill!!
