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.
