It does seem to be changing because last fall, the engine would run perfect to around 3000 rpm, and now we get the injectors cutting out anywhere in the power band.
Agree 100% about confirming computer is bad before you drop ~$800 on a new one. However, I am not sure how you do that since both your injectors are sputtering. My advantage was only one was sputtering and I could switch the lines to confirm it wasn't an injector, etc. Good Luck!!
If its not a competition ski boat, its always second best.
