Hello! I got a used mariner 70 today and got home and set it up. I realized 2 of the 4 corners are not completely flush and even. Even with the pad. It was used and the pad was silicones onto the tank. Is this going to create an issue? Since it’s used should I fill it with some water and see if it sit flush then? The shop is very reputable and open to me going down there but they are closed right now.
