1996 Searay 175XL with the Mercruiser 4.3LX Gen+ Serial OF803642 with 2 barrel carb. I am pretty sure it has Thunderbolt IV ignition. All plugs look great. The engine will start right up on first try in the morning. Engine dies after 5 to 8 seconds of fast idle. Engine will not start after this no matter how you try throttle position or pump throttle. Engine will start and backfire, etc. using starting fluid. After 5 trys of starting fluid the engine will finally start and idle like a champ. No more problems all day after that. Once engine is warm you can start and stop engine all day long. The engine runs great, idles great. It just won't start cold without playing the starter fluid game. What could cause this?
Thanks,
Ken
