I agree, it uppears to have been used in saltwater. Unless it was leaking severely at the seams around that screen I don't think that that is the whole problem.
Inside the pump where that plastic screen came out of. there is a hole that leads inside the ski to the motor. Make sure that hole is clean and clear. It should be about 7/16 of an inch in diameter. I suspect that the hole may be corroded and closed up restricting flow. If there is corrosion, try Forcing either white vinegar or CLR into the hole with say a turkey baster. This should help break down any corrosion. Just be sure to rinse with water after it sets a while.
You can order your needed parts from Babbittsonline go to OEM parts, Yamaha, pwc, yr, model, jet pump 1. Part # 9, & 10 see pic.
