question on a 486ho problem
 

hello guy's i have a 2004 baja ol 25 with a 496ho. the beeper sound every 1 minut or so 2 close bip i really don't know what it is . my gauges and fluid level are ok?? anybody know??

Mine turned out to be the water pressure sensor on bottom of seawater pump.

Probably the easiest and quickest way it to put it on a computer, there will be a trouble code.

Otherwise, what is the last thing that was changed/done on or around your engine? For instance if the impeller was just changed, I would look at the sea pump pressure sender for damage.

your rite, the alarms started shortly after impeller went to pieces..the laptop showed it reporting 40 lbs of pressure and its only supposed to be about 6lbs.
