Warning Alarm

[kj21p]

I just bought a 2006 bayliner with 3.0 mercruiser alpha 1. Took it out for the first time today, started right up and ran just fine for a few hours. After sitting for about 30 minutes I went to start it up and the buzzer won't turn off. All gauges are reading ok. Is there something I'm missing, I am new to this. DO these malfunction alot.

Yeah they can, but I'd take the engine cover off and check the gear oil in the bottle first before blaming an alarm malfunction.

DO these malfunction alot.

Only when something fails.
3 things can cause the alarm to stay on. Low oil pressure, high temperature, and low gear lube in the reservoir.
The alarm sensors arre seperate switches from the gauge senders, so don't confuse the 2.
First check the oil in the reservoir. If it's full, disconnect one of the wires and see if the alarm stops. If it does, you have a defective gear lube alarm switch.
Do the same theing with the temp and oil pressure switch.

If you go up to the Adults only sticky at the top of this forum, there is a link where you can download the OEM service manuals. You need manual #26. It will show you where the switchs are located.
