I have a 1990 Cobia Spirit 180. It has the 3.0 mercruiser in it. It doesn't have a distributor like I expected it would. It didn't run good at WOT, and the tach wasn't working. With it running, I pulled all the plug wires of one at a time, and the #1 cylinder wasn't firing on the plug side, but it was getting spark at the other end. So I replaced the wires, and it worked great!!! I gained 10 MPH. But now it's back to running like crap, and the tach that was working great on one lap of the lake was acting up again. So I checked all the wires again, and got a healthy shock on each one for my efforts. I pulled the plugs, and it looked like they were burning kind of clean. I checked a bunch of crap, found that my negative terminal was messed up on the battery, replaced the battery. Then I wondered about my firing order. I have it with 1-2-3-4 and every place I check has it 1-3-4-2. I didn't change anything on that end. Why would it work good for a while, then not run right after a while? And is 1-3-4-2 the correct. Any insight? I'm also going to take everything apart one at a time and clean it and put it back together. Because everything seems to have at least a little corrosion.
