Seems like lately I can hear the compressor going whoop, whoop, whoop at idle on my 225 Pro XS. Basically I hear it working. But, I don't remember hearing that before. That doesn't mean it hasn't been doing it from day one of ownership. I just don't remember hearing it before. Is this normal or is this dude about to fail? I just pulled the belt about 3 weeks ago and checked the play of the pulley shaft. Shaft had no play and seemed fine when I turned it by hand. Motor is running fine just scared to death that dang compressor is gonna go out and take out my injectors. Motor has some hours on it and it seems from reading the interwebs that this is a point of failure on the opti's.
