I have 2012 Challenger 230 / 520 and my Starboard engine is noticeable louder than my Port side engine. Has anyone every noticed this before on their boat? Could it be a bad resonator on that engine, or a noisy Supercharger? I bought the boat in March and had to work through various issues to get it to run consistently, which it is running fine now. Now I am going through and taking care of the things that "bug" me, like the sound level difference. I did not that the Intercoolers are not the same, the Port side engine (quieter one), has had the Intercooler changed as it is slightly larger and had a vent line running to the back of the transom, the Starboard side does not. The part number on the Starboard engine IC is 276000273, which according to the Seadoo Parts Warehouse is not the correct part number. Although, if you search the web, this number should work on this year and model boat. Any input would be appreciated.
thanks.
thanks.
