First year of owning this boat and learning more and more about it every week it seems.
The ECM went out on port engine. I switch them and problem follows bad ECM.
So GM discontinued these, crusader has zero answer for this other than if I find one somehow, they will program it for me free. I found one on ebay and they programmed it. Got it back and engine fired right up, only when I try to get on plane, it's fine going up to 2900-3000 but then just boggs and surges, like either starved for fuel or ECM is limiting engine performance. Engine ran perfect before ECM failed.
Then I see a post on here from previous owner and it appears he has put automotive injectors from Napa on these engines. 1) is this what possibly caused my ECM to fail? These things are not suppose to go out. 2) What would put ECM into a certain mode to only allow 75% throttle?
It runs smooth as ever in neutral or just trolling around at 1500-1800 and will get up past 3500 with ease in neutral but loaded its like its overruling or something bc if I back off wot it's surges up for a second but then back below 3100
Been a month long battle just figuring out the ECM went south. Going down to change all fuel filters today, It's not acting like a fuel filter problem tho, that usually is hard start issue and dies with throttle increase, this thing sounds great and will hit limiter if I let it in neutral.
The fuel filter has 65 hrs on it since last change. I have added 330 racors sand bypassed the little 110. Is 60 hours a lot for a racor in E10 environment?
