So we were out all day, no issues. We came back to the dock and then this grinding started. Its a 2000 Moomba Outback. Transmission fluid is nice and red, does not smell burnt, and checked and saw no metal shavings in the fluid.. Anyone have any ideas? Best part of the video is my wife saying "Thats not good"

Let me know if the link does not work.
Does it do this in both forward and reverse gear? Would the prop still turn when u put it in gear?Quote:

Hard to tell 100% but it sounds real tinny. Just taking a wild guess but almost like flexplate/torque converter sounding. Almost as if the studs sheared off on the torque converter and are grinding on the flex plate.
Engine recirc water pump. Put your ear up to it and check. I was on a vacation when this started and we ran it to failure as the water temps were fine. The show was over when the pulley disintegrated and fell into the bilge.
Sounds to me like the starters engaging while the engine is running.
That is exactly what it sounds like to me as well, but I’m not sure how/why it would be engaging only when it goes into gear and not at idle. This leads me to think it’s something clutch/pressure plate related. Maybe a pressure plate spring broke and is lodged between the pressure plate and the bell housing? I’m not very familiar with boat transmission internals but assume there are some similarities to automotive (which I’m quite familiar with).Quote:

It really does sound like the starter engaging but as others stated it would do it all the time. I can’t imagine anything in the transmission would make that kind of a noise. Maybe the prop shaft is loose??

Thanks everyone, tonight I am going to hook the hose up to the boat and turn it on and see if it does it in idle. Not sure if I should try to put it into gear, to see if I can replicate the sound to get a better idea where it is coming from. I did find this article which has a video of a very similar sounding grind, let me know what you guys think. Thank you for everythingQuote:

So just for clarification, is it making the noise when the trans in gear or in neutral?
If it’s making the noise in neutral and stops when you put it in gear then I’d absolutely look at the ignition switch/starter electrical circuit and the starter itself.
Could be as its not loaded till its in gear, only free spools. Starter was my first guess but wont do that in gear, it would do it all the time and typically isn't as tinny sounding more of a growl.Quote:

Wouldn't think the sound would quit in neutral though being a water pump, guess it could seen stranger things happen. Need a more pin pointed video to see what its coming from I thinkQuote:

Well good news, I got the hose all hooked up, go to turn it on and boat would not longer turn over. I could not get it to putt, click or anything when I turned the key..Battery is at 88% charged.
Also, I had a bucket of water to keep bearing wet and lubricated if I was able to put it into gear. And like you said, it would of only been for a short period of time.
Also I did find this video which sounds very similar to the sound I am having. And in this thread there is this link, which then says its the ignition switch does not go back to 3/4 after its started so it almost acts like the ignition is still engaged. So I got some lubricant for the ignition switch but never put any in because it would not even turn over. I wanted to recreate the issue, and then lubricate to see if that fixes the issue. Here is the other link:

Go ahead and put a new ignition switch in it, and if it still won’t turn it probably needs a starter.
I took out the starter today, taking it to Auto Zone to get it tested. I will let you know. Thanks for all of your help.
Was the starter the issue?
