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.
Simply not realizing limitations of your boating skill, not paying attention to the conditions, not looking out for other boaters or others in the water and/or lack of judgment are the major causes of PWC accidents. All of these are easily preventable by being cautious, using good judgment and staying alert.
