Re: what causes a boat to porpus. A boat porpoises when the bow is being forced up into the air. It will will reach a certain attidude and then the bow will fall back down causing the up and and down motion. As to why your specific boat is doing this I can't say. Maybe try shifting a bit more weight toward the bow.
This can often be a concern even if there is not a reduction in performance. The most common causes of noise are: 1. Cavitation: The jet unit is starved for water, and usually sounds like a rattle or a can of loose bolts in the back of the boat. Most likely a blocked intake grate.
