Re: something wrong

Idle mixture is still just a bit too lean.

Adjust IN Forward gear while ON THE Water to best idle speed, then turn each mixture screw OUT almost 1/8 turn.

Test acceleration, if ANY hesitation or bog, then turn out just the width of the screwdriver slot and retest acceleration.

Keep at it til perfect.

Then enjoy the ride!
