Shift alarm

[srl]

When backing around after starting the engines to get out of our canal an alarm starts the V. V. says shift alarm. The alarm continues for about 2 mins and the rpm on that engine won't go above 800 rpm. After the alarm turns off everything operates normally. The drives are Bravo Seacore, any ideas?

Do you have DTS?

Try this.

I wrote it up last year when I had a similar (but not exact) problem that you are describing.

Yes Espose4, I do have D.T.S. Thank you for the info, looked at your pics. I think we probably have the same engines; can you tell me about where on the engine the switch is located--it's hard to tell from the pics. Where did you buy the new switch?

It’s a simple 2 wire switch that mounts to the same plate that the shift actuator is on.

It’s right on top of motor, near the starboard exhaust riser.

If someone shifts in and out of gear while you watch, you can see the small pin on the switch as the arm moves from forward to neutral to reverse.

I don’t remember the part number, but it’s a very common item used in many mercury engines, even outboards.

You’re welcome.
For future reference, here are 2 pictures with the switch location circled in yellow.

Follow up: I installed the switch And after I realized that the spacer under the switch fell out of position; I installed it correctly and no more alarms. Thanks again Espose4
