525efi 3 beep alarm
had a alarm sound on me yesterday. Motor started the day fine ran for a while had lunch and as soon as I turned the key I got a 3 beep. Motor idled rough and continued the 3 beep. Got on plane and alarm stoped motor ran great. Went to put put it on the trailer and same thing, 3beep even with out starting the motor. I put new IAC on it about 8 hours ago. Any suggestions, I got the marina going to run a code scanner on it just wondering if anybody had any thoughts without having to pay for that. Appreciate the help in advance. |
Here is the list of 3 beep codes, and with it idling rough might be the TPS

needs to put up his engine serial number first and foremost. earlier 525 are not set up like the later ones. And depending on engine serial number -- they can have voltage issues. I am coming up with a fix for that end VERY SOON.

it is wise to have scan reports to compare every year - year after year. Matter of fact 2 scans a year is good to have ---the reports can be logged to catch issue(s) before they become bigger issues - (comparing reports can help for that ).
A great example just for one parameter to keep eyes on is water pressure readings to compare from beginning boating season to say mid season . I Print all scan reports and keep them on file for everyone that boats that are in my hands. And of course I charge for the scan.. |
Thanks for the help. The serial number is OM905807. |
I'm putting chips on Red and a bad water pressure sensor :duel:.
Ok that is because we just had that sensor go bad. |
I’ll let you know if your the big winner. Thanks for the input. Did you have a rough idle from that sensor? |

A scan of the engine is needed here. |
and for the record
3 beeps 1.5 seconds long not all will put the engine in Guardian mode. Also from the list above here is more 3 beeps 1.5 sec long. Fuel Pressure sensor and failure and or wiring CAN BUS issue(s) Low sensor power So the pick of guessing can get expensive. A scan is needed and the known parameters to see what any of it pin points to. |
Thanks guys, Ill let you know when the scan is done.

Well I got it scanned just did not want to jinx it if it wasn't right. Finally got to work on it last weekend and it turned out to be a $12 plug on the TPS. The mechanic found out if you started wiggling the plug the values were all over the place on the scan tool. Thank you for all your input Part# HP440 on part plus.com. |
