Had code 25 pop up under way. Raw water pump leaking.Replaced pump. Under way the following day and within a hour...code 25 again..long story,andUSboat tow back to marina...the water pressure senser was bad as well..my suggestion would be to replace ...
Good morning,I had the same situation..I tapped a plastic air bleed valve into the discharge line and I open the valve when in the water until all the air is bled out.I know...another hole in the boat..but it works.
