Could be something as simple as the prop hub, or it could be that you have more than one problem. I’m assuming you checked/changed the gear lube and the gearcase wasn’t full of water. Are you sure the shift linkage is adjusted properly? It is easy to misalign that shift rod connector and strip the clamp screws, causing the engine to jump out of gear. I don’t think the missing shift rod cover can have much of an effect, except for a big exhaust leak/noise. I suppose it is possible that the engine is breathing its own exhaust, but not real likely.
The engine might be running on one cylinder, I don’t know what would cause it to sputter and die.
It would be helpful if you could post a video of the engine running/misbehaving.
