I had some problems with my 2005, X10, 350MCX a few weeks back and thought it was maybe oil pressure related. I would get a check engine alarm and no throttle response at lower speeds. I took it in and had a dealer put a computer on it and it came up with TAC faults. They replaced the TAC module and everything seemed fine for 3 or 4 days. Now, I am back where I started with the exact same issues. At times, I can run it for an hour without any problems, but the next hour it happens every time I idle around. If I shut the boat down for a couple of seconds and restart it, there is no alarm and I have complete throttle response again. I have not gotten any alarms at higher speeds, it happens only at idle or low (no wake) speeds. Any ideas?
