Last time I ran the stingray 190lx it ran great for awhile then stopped. Poring fuel in carb started it right up. Checked water separator filter and it was diluted. How is water getting into my tank? And how to even fix something like that what looks to be apart of the boat itself. The only think I can think of is that I did change the sending unit that did take a week to come in. The hole wasn't sealed but just covered. I can't believe that much rain water got into tank that week. Is there a way to visually inspect the tank, if so what is the process. Thanks
