I have a spare compressor with low hours (Less than 190) that was removed from my 3.2L 300XS. I had lost a reed on #6. All parts were then completely replaced with new during the build process. No issues with any wobble, or anything remotely releated to the compressor. If I am not mistaken this compressor should fit multiple Mercury DFI model's (200-225-250-300XS). Engine is freshwater only. $400 shipped. Thanks for looking.
