johnydi 0 Report post Posted June 26, 2017 2000 262 cruiser with a 5.7 mercruiser engine....after operating boat for about 20 minutes the warning alarm keeps beeping loudly, the engine temp read 160F the oil pressure is normal at 40 psi, the voltage is normal at 13 volts or so...I can't figure out why this beeping occurs, the depth gauge does not work and I keep it in the off position but the beeping is non stop, really cannot use the boat until this is corrected, it is very annoying, any advice as to what could be causing this?

Rip5 0 Report post Posted June 26, 2017 Your float in your drive lube reservoir is likely stuck. Pull the wires from it and see if the beep stops. If so, order a new one. Common wear and tear item on Merc's Quote Share this post Link to post Share on other sites
240ES 0 Report post Posted June 26, 2017 I have a 2001 240ES and had a similar problem that turned out to be from low gear lube oil (different from the motor oil) see pics. Hope this helps you. Quote Share this post Link to post Share on other sites
marfi 0 Report post Posted June 29, 2017 I know that engine, there is some sensors on that engine, maybe is a faulty sensor, if all levels are correct and the gauges show everything normal, proprably is a sensor. Call a Mercruiser dealer with a cable to connect to the engine and read the error. I have this on my GPS, so if any problem occurs on the engine i recibe the info with the code and fix if available Quote Share this post Link to post Share on other sites

johnydi 0 Report post Posted July 6, 2017 turns out it was the stern drive reservoir float that was reading the incorrect oil level, alarm buzzer is gone now....you guys really know your stuff, thanks Quote Share this post Link to post Share on other sites

Can anyone tell me what SAL code on my depth finder stands for? Are you in saltwater? And what does that guy have to hook it to his GPS? Where do I get one?
