1998, 200hp Evenrude Ocean Pro controls locked up

I had my boat out for the first time this year. Everything was fine for the first three spots we fished but when we went to leave the last spot the controls wouldn’t throttle. Felt locked up, would move enough to shift but no throttle. Then it wouldn’t run, just stall out from neutral. When I got home I disconnected the shift cable at the motor and the controls shifted fine, cable seemed to function normally. the location of the cable at Neutral was about 1.5 inch off from the linkage. At full throttle it was within 1/4". The cable has a lot more range than the linkage at the motor. below is a video of me moving the throttle manually. What could be causing this? Seems odd the it can go from working to this far off without adjusting anything.

The cable is in the neutral position in this video

I think the problem is the timing advance. The timing base seems to be blocking the linkage from moving the timing advance. Is it possible for that to move out of place. I would think the flywheel and stator would have to be removed for it to move. Any help would be appreciated.

Nobody?

Has the cable knuckle at the motor slipped?

SEEN IT HAPPEN BEFORE
FOLLOW THE THROTTLE LINKAGE UP
THE TIMING ADVANCE KNUCKLE WILL SEIZE OR BREAK AND WEDGE IN PLACE

Thanks Chris. Turns out two bolts came out of the timing base and one sheared. Found them laying in the bottom of the motor.

Finally got the boat running again so I figured I’d post what happened for someone looking in the future. The bolts that hold the housing for the timer base came unbolted and twisted. This was blocking the timing advance and made the controls lock. Took off the flywheel and found bolts gone or sheared off. Had to drill and tap where the bolts sheared. Still not sure why there would be so much torque there to shear bolts, but it happened. Got it together and still wouldn’t run right. Found a crack in my fuel pump housing and replaced the fuel pump. Still wouldn’t run. Check compression and spark, no spark on the starboard side. Thought it was the shift interrupter switch, but that would have been to easy. Bought a DVA adapter and proceeded to test the ignition system. Stator was bad. Replaced stator and all is good, for now. Price you pay for running old boats.

Way to stay with it and ride it to the ground. The only good thing about older engines are parts are usually cheap...if you can find them.

eBay is a great place for parts, got the stator on there for $45. Guaranteed to work.

Man what a train of repairs, i dont envy that. Kudos for sticking with it

Just wanted to update this, what I thought was the timer base was actually Crankcase Head & Bearing assembly. Bolts ended up coming loose again. I’m thinking there was vibration due to bad bearings or bad O-ring. So I bought new parts and I am having a machine shop drill tap and put helicoils in. Just wanted to post an update in case someone searches with the same issue.
