My 2000, 200 Ocean Pro experiences an instantaneous RPM drop / power loss. The loss is 1K RPM?s (say 5500 to 4500 RPM instantaneously) The RPM drop occurs at any RPM in the power band and since I do not run at WOT (5,500RPM) often, please note that it just happens when ever it feels like it, at what ever throttle! I have been plagued w/ this problem for YEARS! The problem has been intermittent in the past and has become predictable of recent. (the intermittent nature has cost me +thousand dollars because when I finally had a mechanic present it worked just fine, and you can?t fix what isn?t broke. (It actually disappeared for a half of season). So far this year it is consistently occurring after it runs for a while. Say after 45 minutes to an hour. It is staying broke more regularly this early season too. In the past it would sometimes fix itself. Instantly just come back, and it may or may not reoccur that day. Or occur and not get better. I would neutral and give a couple of short revs and maybe it would come back, or maybe not. So far this year it seems to want to stay broke after it occurs. I have just shut it off for a short while and it starts w/ renewed full power but then instantly losses power/RPM regularly so far this year. PLEASE HELP ME! When the instantaneous loss of power occurs there is no stutter, awkward vibration or missing signature to its running operation. Just a dismal loss of RPM/power, like it is losing just one cylinder? I have pumped the fuel bulb while running, no effect. Bulb does not collapse and I replaced it in the past as a prevention. Compression has tested OK. I have a new 10 micron fuel separator filter. A new in-line factory fuel filter. All battery contacts/cabling has been wire brushed and dielectric greased. Brand new spark plug wires and plugs. I have replaced the Stator and Power Pack! Last weekend I flushed the carburetor bowls and cleaned the orifices/screws that are inside the outer fuel bowl drainage screws. (need to note for others w/ a general maintenance concern that cleaning the orfices in those internal screws made it run much more responsively during the post effort test run (but the RPM loss problem then occurred anyway 45 minutes later). I found the holes in those screws filled in w/ what I assume is standard accumulation/build up but did not find any thing in the bowls that was tell tale of a particle clog, but since that was the only thing I did, doing so proved to be a good thing responsiveness wise). The ignition coils were replaced systematically during one of my mechanic sponsored evaluations. None were found to be defective but I have ordered (6) new ones and will be replacing them this weekend. I?m sorry for the wordy rambling but can ANYONE HELP ME? PLEASE!
