remote drain plug issues

[Riccochet]

I have a 15' Z521C , I replaced the o ring and the gasket between the plate and hull and it still doesn't seal correctly. I still take on water. Bottom line is that some of these work on some of the hulls and others don't. I'm not overly happen with it and may go to a traditional screw in plug.

Have you taken it back to the dealer? That boat, bow to stern, anything that was installed on it at time of purchase, is covered under warranty for 3 years.
