Need more help. I posted my problem a few weeks ago, but still need more info. I bought this boat with a 1983 Mercury 90 2 stroke. Took it out 2 times. First time it ran great. Second time, after about 20 minutes of running, all of a sudden, it started running really rough and popping. I thought I had run out of fuel, but still had a 1/2 tank. It idles well, but wouldn't accept hardly any throttle input. Also had a lot of blue smoke, like it was running super rich. From what I've been reading, it sound like my problem could be a cracked exhaust splitter? It bothers me that fuel was coming out of the throats of all 3 carbs, like the exhaust has a blockage. I plan on taking the boat in to a local boat mechanic and want to give him all the info I can. Also, if it's going to be an expensive repair, I don't want to bother yet since I don't have a lot of money and would have to save for the repair. Yes, It has fresh fuel with 2 stroke oil, and water is peeing out the tell tale, so I don't think it was overheated. I can see ignition components were replaced in 2017 and then it sat for 3 years, but did have fuel stabilizer in it and the fuel I drained from it did not smell bad.
