Hello & Welcome: tim v

The primary problems could be the carbs are either not getting fuel or the fuel passages within the carbs are restricted or blocked.

Additional possible problems are the fuel pumps are defective or blocked up, no fuel is getting into the fuel pumps, carbs or the filter is blocked, restricted or clogged.

Basically you need to determine why there is no fuel getting into the engine. All fuel system and the related parts could be the problem since the engine starts when primed.

Has the boat sat up for a long time? Or is there a chance that the boat was run out of gas, if so the carbs can pick up water in the bottom of the fuel tank. I seen this happen to 2 1995 750's. Check the fuel/water seperator, mounted near the right side, rear, right under the seat. It will have a small cup that unscrews to come off. Also it has a little red ring that floats in the cup, but only floats in water, not gas. So if is floating all the way to the top, it's full of water, and likely the carbs are as well. I've personally drowned one of these pwc trying to do stunts and showing off etc. Bad thing was, it was the end of the summer and when it died, we just parked it for the year. Next summer it wouldn't start. The water in the carbs sat there over winter and ruined parts in the carbs. Found out that there are steel parts in the carbs. It required rebuilding all 3 of the carbs to get it back in shape. DOH!!
