Sounds like it's in need of some serious carb tuning.

I've noticed blown motors don't idle at a steady RPM, they oscillate or pulse when they idle. What causes that? Is it compressor surge like someone mentioned earlier?

Surge is supposed to be there I think. You're supposed to shift during the down lope. At least that's how my tcm800s were

thanks guys...

thats right.....the idle will clean up at 1400rpms but its hard on bravo drives to shift into gear anything over 1000rpms....it surges from 700 to 1200rpms and i shift it on the downside...

sounds great!! what exactly causes that surge?

running rich at idle...rich then lean at idle is the surge.....cam size duration timing and other factors are involved....mine is set up conservative....

Power and speeds?

If that thing is set up conservatively, I'd love to hear one set on kill. lol

Awesome boat.
