What you are experiencing is cavitation. If your carbon seal has never been changed it's overdue.
This can also be caused by something stuck between your impeller and wear ring. If you haven't replaced your wear ring recently you will need to do that. Having an engine out of alignment can wipe out your carbon seal and wear ring.

You will find all needed parts here in the Green Hulk Store

The carbon seal parts will be in section "propulsion system internal"
You will need parts 37, 35, 36, 34, 40 and 41

The wear ring will be in section "propulsion system external" and it's item 2

The engine mounts are in section "Engine and air intake silencer" and are items 13 and 6

Hope that helps!
