I have a single Volvo Penta KAMD 44 EDC. It is hooked via a jackshaft to a Volvo DP-E drive. It has dual stations. These engines are all fly by wire.
The engine will start and if I press the N button and give it full throttle it will rev up to 2,000 RPM which seems normal. If I put it in reverse and tilt the drive up a bit, the engine will rev up to around 3,000 RPM. If I put it in forward, and give it full throttle it will not rev up higher then about 600 RPM. It seems to shift OK, the tilt gauge seems to work OK.
Boost from the supercharger is right around 7 PSI which seems normal. No unusual sounds, air leaks or fuel leaks that I can detect. It is not revving up high enough for the turbocharger to kick in.
I had the turbocharger rebuilt (the shop that did it said that the old turbo looked fine) and I replaced the lift pump. No change in performance.
Any clues, suggestions, hints on what I should be trying would be appreciated.
Thanks
