Purchased a 89 wj 500. While in the water after about half hour something sucked into water inlet. Pulled out if water and flushed system while taking apart water hoses. Found small debri in one tube and cleared line. Now I started up while runing water threw hose. Blimped throtle and sounded fine from when overhead warrning was on. Took it to river and before puttting it in the water it sounded like the warrning again. What could of happened.
