no water circulation at idle, part III

to recap. i drained the block ended up blowing an impeller. i was having problems getting water to circulate from a fake a lake and so i installed a water hose attachment and the boat seemed to run just fine. i took it too the lake and it wont draw water in at idle. which leads me to believe there may be some impeller pieces in the block. is there a high pressure flush system available?

follow the hose from the pump to to the trans cooler pull the hose on both sides and blow out the cooler 99% of the time when an impeller breaks the pieces end up stuck at the trans cooler

In your other post you said the impeller came with a rubber o-ring that didn't fit and yours has a gasket that you reused.Is it possible the the impeller you got is the wrong one since it didn't come with the right parts to fit your pump?

is it possible jay? yes likely? no. everything was the same with th replacement impeller and i cross matched the sierra impeller with the sherwood impeller on their website.
