Hello all, I just put on a 2004 Optimax 200 on my Cobia. This thing runs nice compare to what I had on there before but while testing it today I was able to go WOT and I had issues.
It appears when I go about 4000 rpm and above it starts to chug ( for lack of better terms).
For example, if I run it at 5000 rmp it will run fine for a short while but then loose a little bit of power then go back up again and then loose a little power again. It continues this cycle whenever I run over 4000RPM.
So issue is running at 5000 RPM drops to 4000rmp (for like a second) goes back up again to 5000 rpm then looses some power again.
I hope this explains my issue clearly.
Does anyone have ideas? Does it sound like a fuel issue?
