We have a 2001 Chaparral with a 5.7 GXi A engine. It has just over 100 hours on the engine, and has worked very well until now. We changed the impeller at around 90 hours.
Before taking it out last weekend, i thought i would attach the muffs to the outdrive and get it warmed up at home first. It had been used without problem about 2 weeks earlier so I didnt expect any problems. After running in the driveway for about 10 minutes, the temperature got up to about 180degrees, so I shut it down. I forgot to lower the leg before starting it, so I guessed the hose in the outdrive may have been kinked. I opened the impeller and the fins had all broken off. The casing around the impellor also got hot and changed color. So i got a new impellor and casing. Before installing them i flushed the hose from the Tstat to the raw water pump to remove any bits of impellor.
I then went to flush the hose from the out drive to the the impellor. I connected the muffs to the outdrive, but, there is no flow at the raw water intake hose. I tried to turn the water pressure to full and squeeze the muffs tight, but still nothing. I brought the garden hose in the boat and flushed into the intake hose at the raw water pump, and water comes out of the intake holes at the outdrive. I again connected the muffs to the outdrive, but water still does not come out the hose at the raw water pump. I went back and forth several times, but water only travels in one direction, from the pump intake hose back to the intake holes on the out drive. I tried to turn the wheel side to side, and tilt the out drive up and down several times with no luck.
I have looked through the "overheating diagnosis" manaul, but no luck. Any help on this would be very much appreciated.
