496 mag ho suspicious performance
 
Hey guy!

bought an outlaw 25 with 496 mag ho last year … tested it last summer and reached pretty good speed at aroud 65 mph … so this year i put it back on water … a fee day ago i remarked having problem going close to 60 … and yesterday i had same issue reaching 55 mph after thinking about it i remembered hearing an alarm about two minutes after cold start … i beeped like two times then stopped … so i read about guardian mode … how can i know whats going on … is it really on guardian mode ??? Idle is good but just not performing as it should

thanks


Marc

You need to scan it to see if it's in guardian mode.

Sorry,,..no shortcuts with a 496 alarm. Scan it.

What year is your 496? 2001?

My 2002 was not smart craft capable even though it said it on the engine cover. A call to very good mercury tech lead to the discovery.

Might want to check before you buy the vessel view.

people said if i have 10 pin connector i should be able to get vesselview , engine is 2003 , but will it get me the info i need thats the question

The VesselView may indicate a fault, but I don't believe it will give you that much detail. I could be wrong, but you may still need a dealer to decipher the problem. I know with the VesselView Mobile dongle the information can be sent real time to a Merc service center of your choosing. They can then help figure out your problem.

Either way, it is a worthwhile investment if you have 496 Smartcraft enabled motors.

I think 14 pin is needed for vesselview

Ok guys little update here .

just went for a ride … caught 61 mph … and felt like i had lots more power … but started the engine and after a while no alarm until i hit the seaway and open the throttle it did two beeps but did not see major perfomance loss … 61 was what i reached at around 4700rpm

One of my buddy will have it scan … some mechanic told me to check compression but my idle is really good and starts like a charm … thiss beeping tells me its a sensor …
