1993 60 HP Merc Warning System questions 0d260043

[mytmouse]

Hi All,

Was on bay this weekend getting a lot more saltwater behind dash then I should. Definitely had moisture on livewell switch which is next to ignition switch. Motor ran beautifully, then after a drift, and a 10 minute run to new area, constant beep, beep, beep beep, beep, that does not end. Motor still runs like a top. Usually when switch is turned to on, it beeps once. Now it does not stop beeping when turned on or running. With what I have read tonight I am guessing, oil, module or warning horn issue. Where should I start first? Any tips appreciated. I do not own a workshop manual. Making that purcahse now online after this post. Thanks in advance as always!

I found this from a post from over a year ago on a 1989 90 HP:

Re: Constant Beep, Beep, Beep...Low Oil Warning

The possibilities...
1. You are below 1/4 tank of oil
2. your oil tank sensor float isn't floating or the magnet fell out
3. your oil tank sensor is bad
4. The warning module is bad

1 is most likely, but you probably already checked that
2 is very common on other smaller models, but maybe it happened to yours
3 is possible but not common
4 is unlikely because a bad module usually sends a constant or ghostly tone, or very rapid beeping

If you can see the float inside the tank, try lifting it with a strategically configured coat hanger. If the beeping goes away you eliminated 3 as a possibility.
Fill the oil tank. If the beeping goes away, you eliminated 1 as a possibility.
Disconnect either of the blue wires from the oil tank sensor. If the beeping stops, you eliminated 4 as a possibility.
----------------------------------------------------------------------
I was probably 3/4 full of oil. So 1 is out!
I dont see an oil tank float (is it a red ball or something???) I am assuming I am the common smaller model noted above.
Where is the Oil Tank Sensor located?....is it visible? Is it testable?
I did disconnect a blue wire, got the beep to go away. So 4 is out! (ok, now that I see what I am typing, follow that blue wire to the Oil Tank Sensor...but is it testable?)
Should i consider removing the oil via siphon then removing the tank to find the float and magnet? I see where the blue wires attach at front bottom (with a mirror) and I see where the green 1/4" line or so comes out from the bottom rear. I assume that little square job it plugs into is the oil pump.
I see the tank at mercruiserparts.com 1263-812718T1 Looks like a no brainer for 70.00, assuming the float is in there.
It also contains the cap and its seal. I also see a switch with a harness (Item 10) for 14.00 87-12886A6 any clue what this switch is? Is it the float?


Also, while searching for the blue wires....there is that main big round plug ( I will call it the in from the boat) with 8-10 or so studs that of course plug into receptacle on that same side. coming out the back end of it is a Blue/White wire, a Green/White wire, which are both connected to there respective wires, but there is also a Brown/White Male quick disconnect and a Tan Female quick disconnect.....What are these 2 for? They are not connected to anything.

Thanks in advance

Bump for help.

I went ahead and ordered a oil tank/manual etc thinking it is the float. Still would like some direction please.

Tank arrived today, 2 hours later its in.
turned key, beep beep beep still there
I drained oil
laid old tank upside down
turned key
beep beep beep gone
removed oil line to motor
removed probe pin/harness (simply a screw with a waasher holding in the probe/pin (look like a 3" bolt with no threads)
put in new tank
screwed probe down
attached oil line
filled with oil (took less oil then came out)
turned key
beep beep beep gone


Also, one of my questions I still need help with as the dealer only ordered the owners manual, not maintenance!!!! i have to wait.

there is that "main" big round plug ( I will call it the in from the boat) with 8-10 or so studs that of course plug into receptacle on the same right side. coming out the back end of it is a Blue/White wire and a Green/White wire, which are both connected to there respective wires, but there is also a Brown/White Male quick disconnect and a Tan Female quick disconnect, connected to nothing at all.....What are these 2 for? They are not connected to anything.
Anyone? Are they oil pres and temp ? My gut says the other end is in my dash, not used. oil temp and/or pres maybe?????

help,
thanks,
