Hi folks - hoping you can help me. I have a new 2017 VR5 with the 4.3 MPI 220hp Mercruiser. The thing has died four times already in the past week. I believe it's flooding.
I've read a lot that these engines have problems with vapor lock from getting too hot, but I don't believe that's the issue here. The first two times it killed it was just slowly maneuvering out of my slip after running for only a couple minutes.
The first time, it wouldn't start up, so we just let it sit for about a half hour. It started after that. The second time, I realized it might be flooded and tried starting it in WOT and it fired right up. The third and fourth time also it started up with a WOT start.
Is this a problem with the idle speed perhaps? It dies while shifting from gear back to neutral. Is there a way to adjust the IAC to increase the idle? Or am I completely off in assuming it's flooding due to low idle?
Thanks!!
