Grinding when coming into the dock.

[RideMoomba34]

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"

Does it do this in both forward and reverse gear? Would the prop still turn when u put it in gear?

It did it on both. I was able to put the boat back on the trailer. I was also able to freely move the prop once loaded on the trailer.

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.

No that can’t be it since the pressure plate is always rotating with the engine regardless of if it’s in gear or neutral....

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.

The sound is dead on when my water pump was failing. I guess I've seen a thing or two.

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 think
