Alarm every 1min and 30 seconds while running

[Chap264]

I've got 8.2 L Merc. When I turn the key to start the engine there is an extended alarm that goes off assuming to tell there is an active alarm. When I start the boat, the Alarm goes off every 1:30 seconds.
Everything says Gear Lube Reservoir. I've unplugged the Gear Lube sensor line and the alarm doesn't stop.
The Dash doesn't show any active codes

Gear Lube is full in upper and lower.

Its nice you have a 8.2 ltr. Engine.

Do you have any idea how many years and how many configurations that engine has been used in?

Maybe share ALL THE SPECIFICATIONS OF YOUR BOAT.
YEAR
SERIAL NUMBER
EFI/MPI/ CARBED
ANY RECENT REPAIRS/HISTORY
ECT. ECT. ECT.......

Details matter, specification matter...
