Hi, I have an 85 sunbird with the 3.0 mercruiser, was out on the water a couple weeks ago and all was good. till I was wot and the boat just quit, would not start or even sound like it wanted to. So i figured out there was no spark, i put a new coil in it, and it started right up. thought i fixed it, no such luck, was out again the same thing in wot stalled and never started again. hoping somebody could point me in the direction to go. Thanks.
