tightening screws from the inside is not going to stop leaking windows. the only thing that stops water from getting into your boat through the porthole windows is silicone. if your gasket is bad, that's one thing, but all the screws on the inner assemble just hold it to the hull, they will not stop water from coming into the porthole frame. tightening the screws on the inside will probably spin the nuts on the outside and chew up your silicone, causing more of a leak.
Stopping a leak involves sealing the origin. If the origin is bedding gone bad, the porthole needs to be re-bedded and nothing less will cure the problem. If the origin is at the dog screws, re-bedding the porthole without tightening the dog screws is equally as useless.
