Looking for some advice as we are very frustrated. We own a 92 Sea Ray Sundancer. Our boat died on the lake and wouldn't start. We took it to the mechanic and he told us we had water in the gas. He drained the tank and changed the cap and rotor and charged us $200. We took it back to the lake and it did the same thing so back to the mechanic. He drained tank again and told us we needed a fuel/water filter and he installed and also pressurized the tank to make sure we didn't have any leaks, another $200. We took to the lake and it ran AWESOME for about 3 trips. Yesterday, it died on the lake AGAIN. I checked the fuel/water filter and it was full of water. Dumped it and it was still not running right so I checked the filter about 10 minutes later and it was full of water. The boat died again as we drove to put it on the trailer. We don't know what to do and are very frustrated. Please help!!!!!!!
