Hello, 2003 Four Winns Horizon with Volvo Penta 4.3 SX will not move FWD or REV. RPM increases no motion. Quick inspection shift cable attached to shift shoe. Shift shoe moves with fwd/rev throttle movement. Also stays neutral with neutral button pressed. Throttle Shift disengage button and neutral button appear to return to neutral in neutral position. Sometimes I’ll need to move throttle back and forth to get it back to neutral position. Propeller is locked will not move with engine on or off. Owned boat for a month now not sure if propeller was spinning freely before. Happened out middle of the lake. Any help is appreciated.

Has oil, did not see any bubbles.
Didn't ask about bubbles. Just want to make sure gear oil in drive us full/clean. You checked the dipstick/monitor?

If so and you're satisfied the gear oil is sufficient you should remove the drive and inspect the engine coupler/drive shaft splines

Is the cable and shift assembly at the drive moving with the helm controls? Yes or No

If Yes, your issue is in the drive transmission (upper gear box)

If No, you have a control or cable issue

This is all you need to know. Something is wrong in the drive.
Time to pull the drive and find out why.

Make sure the cable is being held in place at the outdrive end, sometimes the little 3/8 bolt that keeps the cable in place comes loose or just plan falls out

Fixed throttle spring was out. Initially feedback was as if everything was working properly. Glad it wasn’t bigger issue. Thank you all for replying
