throttle lever/cable problems??

Jason, you have 2 separate issues.

First for the throttle I think you probably need to replace the control cables. Get under the gunwale and remove the cotter pins on the cable swivels. Pull the swivels out of the control levers on the MV2 and DO NOT Spin the swivels on the cable or you'll mess up your adjustment.

Now with those removed push your throttle lever back and forth and see if there is a difference in the way it feels, should smooth as silk. If it is, just order some new cables and you'll be fine. If it is still sticky you'll need to remove the MV2 and clean and regrease it.

Do that step and let us know what happens. We'll walk you through either situation to get it rectified.

For your other problem please post a little more about your engine and ignition system. Since your boat is not a CC I'm not sure whats in it. My first thought on the popping though is timing or lean condition with the carb. What is the condition of the tune up on the engine and who performed it for you last.

If your not sure what you've got in the boat just post a photo of the motor.
