Mercruiser 5.0 MPI Bravo III
I have a 2004 Sea Ray 220 Select with a Mercruiser 5.0 MPI Bravo 3 engine. I am attempting to replace my impeller but seem to be having a difficult time figuring out how to get to the thing. Do I need to remove one of the idler pulleys to get to the hoses to disconnect the inlet and outlet hoses? Should I take the serpentine belt off first? Any help with this frustrating problem would be appreciated. Thank you in advance for reading and responding.
 
If I remember correctly,
Remove serpentine belt.
Unbolt the pump and let it drop.
Remove inlet and outlet hoses.

CAUTION!!!!
If the boat is in the water, raw water will flood the boat through the open inlet hose.
Plug it and don’t leave the boat unattended.
 
Remove the three bolts holding the pump bracket to the engine.
