Recently purchased 353 with twin 525 efi's with bravo xr's, 196 hours. Got alarm--double beep every minute from port engine. Manual says alarm indicates low drive fluid. Added 1/4 quart drive fluid to port engine. Reservoir indicates "full". Boat has been driven three times since adding fluid, but alarm still sounds every minute. Does system need to be bled? How do I reset alarm?

Could be the float stuck to the bottom of the bottle, it could also be like 12 other things. Two beeps every minute is a common alarm, does it go constant over 4k RPMs ?

two beeps every 60 seconds at any rpm, neutral, forward, and reverse. fluid was def low, but has been topped off. The merc manual lists low drive lube as the only problem with two-beep alarm. My old 496 gave two beeps for three or four problems. Is the low drive lube sensor in the reservoir?

my low gear lube alarm in my 292 a constant alarm, not a double beep.

Yup..... mine does the same thing. Constant beep.

On mine its in the bottle, on the bottom.
