35hp Chrysler motor w/ water circulation problem.?

Question

Installed new impeller, checked thermostat, checked and blew out all hoses...water still does not circulate. Where is the water pressure relief valve and what does it do? Any help or suggestions as to why water is not circulating through this motor would be appreciated.

Answer 1

You should check for obstructions in the system.  I once had a family of wasps build a nest on the interior of the water jacket-I had to completely disassemble the motor and drive to find it, and I had to have the power head "boiled" out to get rid of it, but it did work well.  First i would re-check the installation of the impeller, make absolute certain it is functioning.  The relief valve is on the power head, if you have one.

Answer 2

Just a guess---- thermostat is in backwards, take it out and see what happens.
