Hi All, I just purchased my first boat, a 17 foot speed boat and it has a 135 Mercury outboard. I have no manuals so Google is my best friend and I turned up here pretty quickly. I have had a good look around the net and have some questions about how I should expect the alarm system to work, and how to test it too.
The Serial Number is 0B333118 which I beleive is a 1988 model, it is a V6 2-stroke with oil injection (seperate oil tank) and I beleive it is 2.0 litres in capacity.
It starts, runs and the gears seem ok Forward and reverse) and so far I have only run it up in a water tank.
As an automotive petrol-head, I wish to make sure it is in good shape before taking it out on the open waters.
So,
1/ after I have inserted the key and when I turn the ignition on, should I hear any alarms or check beeps? (I though I would, just to be sure that the alarm buzzer works)
See here for a pic of my controller, not sure of the model, but it has a kill swith (which works) a choke lever (seems to do nothing) and a "throttle friction" rotary switch.

2/ How do I check the over temp sensor? (will it only work when the engine is running, or can I check the functionality when the engine is NOT running, which I would prefer)?
I read on the net about a tan wire. Is it the one that comes out of the bottom of the wiring loom multiplug and goes to the the top half of the Left Hand cylinder head? if so, I guess I can check the alarm by disconnecting this wire and grounding it?
When I tried this, nothing happened, actually, I checked the continuity and the wire is constantly grounded through what I am assuming is the temp sensor.
Here are some pics of this wire and where it goes to.

Should I remove this sensor, clean it up and check it on a test rig?
The dash on the boat has a temp gauge. I dont know if it works, so I am not sure if this tan wire sensor (if it is one) is the temp gauge sensor or if it is the alarm temp sensore?
3/ How do I check the low oil condition?
I removed the filler lid, to expose the float, and hoped that as the float fell, an alarm would sound, maybe a beep beep beep beep?
Nothing sounded.
I checked the continuity of the float switch, and it works, there is continuity when the float is at the bottom of its travel.
So, are my expectations of how the alarm features should work, correct?
A/ a test alarm when the ignition is turned on,
B/ a constant alarm for over temp condition
and
C/ an on/off alarm for low oil condition.
Many thanks is advance, I did search this site but did not find a comprehansive answer.
