My 40 leaked in the same spots. One big problem I noticed is the rubber gaskets expand and contract so if oyu don't put some sealer in the openings you're going to have leaks. I've heard several guys that run nothing but traditional type rods say if you don't want your cowl vent to leak, fill it in. I replaced my gasket and adjusted it and it got better.

Mine has been pretty dry since 2012 though....................................
