    slow on plane

    pick my boat up from just getting air pump,2 injectors and plugs replaced from
    air pump going bad [would not run]
    went out today ran fine all morning then started to notice slow to get on plane
    when hit throttle would feel like bogs down for about 2 seconds then respond.
    and get on plane and run good.
    I know this was not dealers fault and i am not blaming them.

    Re: slow on plane (hemi1)

    Suggest you get it back to them asap.

    The problem MAY, or MAY NOT be related to the failed air compressor....

    One thing commonly missed when a compressor fails, is that the air inlet fitting (for the air pressure line from the compressor to the Starboard rail) is VERY small, and can sometimes trap small pieces of debris from a failed compressor (which can later block the fitting, or even eventually pass through it, blocking direct injectors).

    Another common item is that spark plugs can easily become fouled after a compressor failure (due to an inappropriate air/fuel pressure ratio at the direct injectors).
