... just be aWARE that not silicones are made for application or use on aluminum, where the curing agent can corrode tin ...A couple of ideas and observations:
I use a hole saw to cut through the hull for the through hull. Dozens done and never a problem. Use silicone sealer and stainless hose clamps. Screw the pump to a piece of cutting board (or HDPE), to keep the pump upright and out of the debris. Replacement will be a breeze. If you get vibration, glue the HDPE to the hull with a dollop of silicone sealant.
