Hi, I posted this on the Scarab Facebook page but haven't received an answer.
4h ago (boat engine time), I got a P0303 code (along with a check engine light, NOT the wrench) which corresponded to a misfire on a cylinder. I immediately suspected the spark plug since I haven't changed them in over 125h of use. I take them off every year, inspect them and reinstall. Everything had been running fine until recently and when it started running rough, I essentially got that code right away. Regardless, I intentionally kept using the same plug and kept a spare set in the boat along with the tools in case I needed to replace them. No biggie. So I did.
Boat is running perfectly since. I have now put about 4h on the boat over a dozen sessions if not more. The code indeed went away as I was told if the problem was fixed. BUT the check engine light has NOT. I still get it each time I turn the engine on. Everything still running smooth and perfect.
Can anyone confirm if the check engine light should have gone away by now? Or does the code go away, but you still need to reset the check engine light? If so, I'll consider just buying the candoo pro software, just trying to avoid that expensive if possible. Dealers are pretty far away... and if I have to pay them for this, I'd rather just buy the software instead since I plan on keeping this boat for a long time.
With that in mind, the other possibility I considered was my battery which is now on its 4th season of use. I have no issues starting the boat and no issues running everything like normal. The battery, at rest registers as 12.73V on my multi-meter. So to the best of my knowledge, the battery is perfectly fine still. It's also on a battery tender all winter and I recently added a solar trickle charger while I'm away from the boat since it sits in the water for many days at a time with nobody around. So to rule that out, I took my car battery and put it in the boat to see what would happen. After running the boat for a just 10 min, no difference. I ran out of time before leaving the cottage so couldn't keep running it to see if the check engine line would eventually go away like the code.
Anybody know for a fact why the check engine light would still be on with NO code whatsoever at this point? And yes, there is NO active fault code anywhere in the display. I've tried every trick in the book.
This is the older model 2015 Scarab 165 (150HP).
Merci!
