So I finally got my boat back from the mechanic and he ran the diag and put it out on the water.
He got error code 3; low water pressure.
I just changed out the impeller.
He has isolated it to the raw water hose that goes from the Bravo III outdrive to the engine.
This is what he quoted me:
To change out the raw water hose and insert and replace the block pressure sensor.
Parts required:
Block pressure sensor
Drive gasket kit
Raw water hose
Insert x2
Gasket
Total Parts $170.02
Labor $ 1377.50
15 hours labor.
I guess the outdrive has to come off and he has to work inside of it.
Does that sound about right? This has not been my year.

On an aside note, the engine was running a little hot so i decided to change out the thermostat. The only thing i found was the outer ring. Someone had punched it out so it was running without a thermostat. I know it wasn't corroded out because it looks like it was cut off. Why would someone do that?
