Make sure they installed the correct software on your boat. I had an o2 sensor go out the first time I had the boat out which flashed a check engine prompt (I have an '08 w/340 HP CAT ETX). Took it to the dealership I purchased the boat from, installed a new sensor and they loaded Moomba software on the ECU and my perfect pass would not work at all next time out. Possibly they uploaded the wrong version of the software on your ECU. I actually had to take it to a different Indmar dealer to get it properly installed. Some of the these shops have no idea what they are doing.
They were dragging there feet on this, so I started to get involved and called Skiers Choice to expedite the process. This helped a lot, even though my boat was still in the shop for two weeks. Might want to conider calling Anthony or Matt Brown at Skiers Choice, explain to them the problem, where the boat is at and get them moving on it.
