Prop spins in neutral

[millerda68]

Brought my 2010 home for a thorough cleaning and to test a fake-a-lake I built. I noticed the prop spinning in neutral. I don't think there should be any spin at all. Any ideas on what/where to check?

Spinning slowly?

[millerda68]

Yes slowly.

Ok, I say it's normal. You can check your strut bushing for play by grabbing the prop and seeing if there's any movement. You can also check your engine/shaft alignment. Both my inboards moved slowly in neutral and were properly aligned and my strut bushings were good.

I've been hearing this same thing about outboards, IO's and inboards my whole life. That's why we always shut down when a rider is in the water near the stern.

even on a fake a lake, isn't there water running to the dripless seal? would that be enough pressure to rotate the shaft?

Yes water is running to the seal, no there is no physical reason the water flow would spin the shaft. The shaft is spinning due to fluid flowing through the transmission. Completely normal.

Thanks for the replies. Much appreciated.

Though I dont recomend it. You can reach down and stop the spin. It is just as mentioned, the mere shear force on the fluids.

I was getting more than just an idle spin on the prop. It was under power. I took it to AWS to get checked out today. The clutch plates are warped and thus the transmission is not disengaging. So, sounds like new transmission time. I have asked them to check into the warranty from indmar to see if anything is covered there.

Complete bummer! But I guess the good news is we are near the end of the season and I only had 3 weekends left that I could have been out on the water. They should have the parts here in about a week and then some labor to get all changed out. With any luck I can have it back and still get on the water before the weather turns crappy.

Any thoughts on what caused the warping?

Abused by the prior owner.

Throw in new plates, not a complete transmission.
