I have a 7kva Onan Marine Generator
which I just removed broken pieces of impeller out of inlet to heat exchanger
Now when I start this unit, motor
runs as normal but there is minimal outflow of raw water
plus the outlet hose from impeller housing is very firm (as if there is excess pressure in this hose).
With unit shut down & this output hose disconnected from impeller housing, I can not blow through it (ie through heat exchanger). With outlet side of heat exchanger
removed, I can blow through this hose. Is this normal? I assume not. What could be causing this blockage?
Note, before I cleaned out heat exchanger, generator
was working normally.
One step forwards, two steps backwards!
I would appreciate any input,
