Can a faulty starter motor stall an engine?

[HueyHuey]

I might have a starter motor that does not disengage after starting.
I have a Yanmar 3jh2tce motor. Whilst underway I heard a scratchy strange sound coming from the motor immidiately before the motor stalled. Upon anchoring I found the starter cable had broken. I replaced the starter cable then found the relay had burnt out. I jumped the starter solenoid and the motor started but still had the sound, it ran underway for about 15 mins before stalling again. I changed both fuel filters which were overdue. Started the motor and the sound was still there, after about 10 mins the motor shook once (like when you remove a spark plug lead on a car) so I immidiately hit the stop solenoid to kill the motor.
My initial thoughts were fuel supply....
But now I suspect a faulty starter motor not disengaging and perhaps after heating up it puts a load on the motor and stalls???
This may explain the broken starter cable???
The starter is quite hard to access and would have to be done by feel only...

Assuming the bendix stuck then eventually the starter is going to seize, and yes that can lock up an engine

Not sure what you mean by starter cable, many years ago starters were engaged by pulling hard on a cable, that engaged the bendix and on some it also closed contacts that powered the starter, I have a 1946 airplane that is done that way, and if you have ever driven an old car there was a pedal on the floor that did the same thing.

What kind of engine do you have?

My motor is a yanmar 3jh2tce.
I just started it again, it starts easily. By the sound is crackle scratchy sound that gets worse with engine revs, eventually stalling the motor.
I ran the motor for about 5 mins changing gears, increasing revs in neutral then cut the motor. I checked the temp of the starter motor by hand and it wasn't hot.
I restarted the motor and shorted the wires to the solenoid and it ground the starter gears.....
So my way of thinking is that the starter motor must NOT be stuck in engaged because it tried to re engage again.
So if not the starter what else would cause the noise and stalls the motor?
Could they be unrelated problems as my start battery got really hot and died as well???
If I was back at port I would get a mechanic out... but I don't think they will come out here...😫

The starter cable is the main positive power cable to the starter.

Sounds more like a drive plate dampener just as a guess.
But that’s just trying to think of what could make the sound your hearing is all.

Would this stall the motor after 10 to 15 mins?

I think if you pull the starter you will be able to tell if the bendix is stuck out.

I had this issue on my 2001 universal 35. I have a starter button and it would stick after start. I only noticed it because of a strange noise. I punched the starter button and it unstuck and the starter disengaged. I eventually had to change the button.

Brief history
Kohler 5 E - water cooled , marine generator
Twin engine cruiser ,

Started generator from cabin , after 5 minutes of running a HUGE
MOUTANIN OF BLACK SMOKE coming from under deck ,
Looked like boat was on fire
After this happened starter would do nothing , Jumping solenoid
nothing , Getting too starter impossible , engine has too come out

Port engine came out recently , access too generator
Starter was fried , THE burning smell that looked like boat was on fire
came from starter .
Starter got stuck in start position causing the SMOKE
Discovered Crank Shaft was frozen , would not turn .
Don't know if crank shaft froze causing starter too freeze or two
un related issues occurring at same time ? Heat exchanger might
be cause leaking water into cylinders ,

Put transmission fluid into the spark plug wholes , After a week
crank shaft turned
Installed new starter ,solenoid ,battery cables , Engine starts ,

I was always under the impression starter just starts engine , never
had a starter smoke too this degree
