2002-2004 Mercury 40HP, 50HP, 60HP Throttle Link Adjustment
Adjustment
NOTE: For remote control models, remove remote control throttle cable during throttle link adjustment. For tiller handle models, throttle cables remain attached and throttle twist grip should be used to advance throttle during throttle link adjustment.
- Lightly hold throttle body arm against idle stop.
- Slowly push throttle lever forward until you feel the throttle body start to move. The center of throttle arm roller should line up with the throttle cam alignment mark. If adjustment is needed proceed to next step. Tolerance may range from mark to 1/8 inch (3.2 mm) after mark.
- Remove lower cowl. Refer to Cowl Removal section 5A.
- Disconnect the throttle link rod from the throttle arm and throttle body arm.
- If the throttle body arm engages (throttle shutter opens) before the center of the roller aligns with the throttle cam alignment mark, shorten the link rod by turning the socket clockwise. If the throttle body arm engages after the roller aligns with the throttle cam alignment mark, lengthen the link rod by turning the socket counterclockwise.
- Snap socket onto throttle body arm and push rod end into throttle arm.
- Repeat steps 1 & 2. Adjust if necessary.
