    My understanding is that cavitation in a jet pump is the creation of vacuum ‘bubbles’ in the liquid. There is literally nothing in the cavitation bubbles, no air, no water. Just empty spaces (a...

    Sticky: Resealing the jet pump sections during reassembly?

    Well, air leaks cause pump ventilation, not cavitation. Different causes, similar effects ;)

    There is nearly 1/4" gap between the Worx intake grate and the transom plate on my hull. I may have to craft a rubber 'spacer' to fill up that gap, otherwise it is going to be (even more of) a messy...

    The visible air gap in the sealant was in the lower half, where the intake grate meets the transom plate, so I removed the intake grate.
