I have a 97 sport nautique that has given me many years of trouble free service. Last year was a very wet and rainy year and the boat didn't get used much and sat on the lift with high moisture in the engine box. When I went to put it away last fall the engine would start and run for a couple of seconds then shutdown. The center relay button on the back of the engine would be popped out. You can push this button in and it will start and run again for about 2 or 3 seconds then shut down. Is this a bad fuel relay or something else? Please help, the nearest Nautique dealer is over 100 miles away.
