I have bought a 1996 Sea Ray 240 with the 5.7 L with Bravo III out drive and has the Thunderbolt ignition. My problem is when the temp gets up to 160 or higher the engine quits and will not restart until cools down. The marina replaced the coil and the dist. pickup, same problem, they then replaced the ignition control module same problem, they then said the carb needs rebuilding did that same problem. engine runs fine in the slip the temp stays at 130 only when running the boat and the temp gets up to 160 is when it quits. No warning it's like I just turned the key off. Any help seeing the marina can not seem to find the problem. This only started after I fill the boat up with new gas ran fine with old tank of fuel, I did change the filter/ separator.
