I have a KAD42 in my boat, i have noticed a slow drop of max speed during 5 years or so, as i test always when the boat goes into water in spring i know i have almost the same test environment. Latley the engine have started to give me some things to fix.
the engine runs very nice, starts direct, when i rev up to get in speed the engine revs up quick to app. 2600rpm, the compressor disengages, and then the rpm drops to app 2300(still with open trottle)then the compressor kicks in again push the rpm up to 2600 and then disengags but this time the Engine revs up very slow to 2700, 2800 and then the turbo kicks in and the boat rockets up to max rpm.
Any ideas?, the turbo? the compresor or any sensor for the compressor? I feel the compressor disengages to early? any ideas to fix?
