I have twin Kad 42's and the starboard has a compressor problem.
revving the engine in neutral, the compressor cuts in at around 1800rpm but the engine revs immediately drop 300 rpm and the compressor 'whine' drops down too. Opening the throttle more does bring the revs up a little, but it 'dithers'. The belts are fine and the 'spinning' plate at the front of the pulley, can be freely turned by hand. On test runs, with throttles wide open, the port climbs swiftly to around 4200rpm, but the starboard climbs slowly and struggles to reach 3700rpm - can anyone help please!
