rumble in lower unit

[dan313]

Good Morning,

I've noticed a rumble from my Bravo 3 drive. When I move the drive up or down under a load I hear a rumbling noise. After I set the drive the noise stops.

Any ideas?

Thanks,

I heard strange noises from the trim pump when I had a hydraulic leak in one of the hoses. Once the level was low enough to let air in the pump it made all sorts of noises.

Thanks for the reply. I had the trim hoses changed because of a leak. I did not have the noise before I changed the hoses. I will have to bleed the pump and see if that fixes the problem.
