Great. There was a design change in 2016, I need to see which one you have to best help you. The only way for me to do that is with that serial number for the engine.

Close, that is the model number. All Mercury engines are categorized by their serial numbers.

Customer: replied 8 months ago.
That’s all I have. Right now
Customer: replied 8 months ago.
Any guess
Expert:  Charles replied 8 months ago.

Lets look at the cables on the engine. Remove the hood, and look to see where the shift arm is currently with the controls in neutral. Then shift to fwd and see if that shift moves any in the forward direction.

Customer: replied 8 months ago.
The throttle moves freely
Expert:  Charles replied 8 months ago.

If the shift cables does not move at all, take off the nut, or pin that holds the cable end to the engine, then try to pull out of the black part of the cable end. See if it moves any at all.

Customer: replied 8 months ago.
