Can you run a boat without a prop

[jjgag60]

I need to fix a noise coming from inside my boat while in gear at a specific rpm (under 2,000). I thought about removing the prop and backing the boat and trailer into the water and then starting it. Does anyone know if you could damage anything by doing this? By leaving it on the trailer i can spend more time finding the noise.

You will be fine. Do not let the motor over rev. It might be that the noise needs the thrust load of the prop, so do not be surprised if the noise goes away.

Would it not be the same to just rev it in nuetral?

If you have cruise with the rpm feature, use it.

Thank you for the suggestions. I think Daniel is right, my noise is only in "gear" so without the prop the noise may go away. I will try the RPM cruise and then have someone drive, while I look and listen. Thanks everyone.

Get a stethoscope from the auto parts store....don't stick the rod or you body parts in rotating engine parts.
