Hello all, I am looking for help as I am having issues with my 1998 Mercruiser 3.0 I/O stalling randomly while out on the lake. Engine runs excellently on muffs. I have replaced the spark plugs, and just got the boat back from having the carburetor rebuilt at a shop. Carb was quite gunked up prior to rebuild. My problem is that I am still having the same issue with engine stalling when I took it out on the lake today. I had it up on plane on and off for probably 10 mins today and it was running great until it just wasn’t. It will also randomly stall at idle as well. See attachment for video of stalling. Thanks!
