I took my boat to a local reputable shop after I had some engine issues. I was told the CDI box was going bad (loosing spark on cylinders #2 and #5 above 2000 rpms). I ordered a new one from a shop in Arkansas and installed it on my motor. Took the boat out yesterday and it’s doing the exact same thing that it was prior to me replacing the CDI (sluggish out of the hole, top end was weak, and only turning 4500rpm max instead of the typical 5500 rpm). Do you guys have any idea what other problem I could have? I have questioned if the new CDI I ordered could be faulty or if that is even the problem since it didn’t change anything. Anything is appreciated. Thanks guys.
