Get an OMC factory service manual and go from there.

Try flushing the fuel system, then try again with fresh fuel. To be on the safe side, use a 50:1 premix in case the VRO has packed it in. Also check to see if there is water circulating. Get an Owners Manual to explain what the horn is alarming about, and a Factory Service Manual so you can troubleshoot the problem

I think I just said that. O 'Well.

(VRO Horn Warnings)
(J. Reeves)

NOTE: I retired around 1991/92. Possibly some of the later V4 engines and others may also incorporate a fuel vacuum switch that would enable a fuel restriction warning to sound as mentioned below, an unknown factor to myself.

1 - A steady constant beep = Overheating - The V/6 engines, possibly some others, have a fuel restriction warning which is also a steady constant beep.

2 - A beep every 20 or 40 seconds = oil level has dropped to 1/4 tank. (Late model engine = Every 40 seconds)

3 - A beep every other second = VRO failure, air leak in oil line, oil restriction, (anything that would result in a lack of oil being supplied to the engine).

NOTE - If the warning horn is the black plastic (overpriced) three wire type horn, the warning horn should beep once when the ignition key is turned to the ON position. If it does not, it is either faulty or someone has disconnected it (a stupid move!). At any rate, if it does not beep which indicates that the horn is non functional, find out why and do not run the engine until the problem is corrected.

On that motor steady horn should mean overheating. Check your thermostats. The water will still come out the pee hole.
