I am getting an alarm on my 1992 xr6 mercury. HOW CAN i TELL WHAT IIT IS

what you are trying to say is that the engine wont rev up? or it revs up fine with no load but cant rev up when trying to push the boat? maybe its still running on 5 cylinders

Good Day,
If The Alarm Is continuous It Is Most Likely The Water Pump Impeller Needs Replacing Including Gaskets And Rubber Seal,
If It Is An Intermittent Alarm It Is Lube Oil Level .

Product Line Year H.P. Model Number Model Description MERCURY 1993 150XR6 1150453ND 135/150/175/200/XR6/MAGNUM III https://www.perfprotech.com/

You dont, you go to parts store snd get a new one , they are cheap.

ok , this is true for all cars, and the newer they are the more beeps.
mine beeps if the planets are out of aligment, with 14 on board computers.
this is all covered in the operators guide, why and who. lost that?
is your car a honda. we cant tell, its posted to honda accord
but you then say marquiz. and not 1992 ,.... why?
if a Mercury Grand Marquis , then post to mercury. for best help
not to many honda experts work Mercury. but good luck.

get the operators guide.
or look here for lamps errors.

sounds like a problem with the unit, either the unlock output isn't hooked up, or it's bad...

go to or call an auto pARTS STORE they can tell you the plug gap.

if u got ur title u can get a duplicate key at the dealer for like $8 or u can get one of those pop a lock tools at the auto parts store theyre cheaper than a locksmith and they use te samething u just put the wedge in window and slide the th hook in and unlock the door
