Alarm issue?

Today I had the boat out on the water after two months of sitting. It was running fine until the alarm started to sound. She still ran good after the alarm sounded but the alarm was a concern to me. It did not sound like the typical alarm that sound when there is no oil. It sounded like it was sorting out somewhere. Did not over heat and water was coming out of the pee hole. The motor is a 1987 225 evinrude, great motor. If anyone has any idea what it could have been so I can know where to look. Also I want to change the vro-pump out for a straight fuel pump. For some reason I believe it has to due with the vro-pump failing. Any help will be appreciated.
 
It could be just a horn going bad. As far as the vro, disconnect the oiling system, mix your fuel 50:1 and use the vro as a fuel pump only.
 
Never though of that but as far as the vro pump the nipple that holds the hose that is connected to the gas tank has broken off. So I used J.B Weld to clue it back together and the mechanic said if that does not work I would have to buy a new one. But if I am going to eliminate the oil section could I just buy a fuel pump?
 
You should be aware of the different sounding alarms and what they indicate. Which of the following did you receive?

(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.
 
Thanks Joe, yea it seems like it was steady but it also sounded like every other second. I believe that the vro-pump has a air leak. Like I said before the nipple of the vro-pump is loose because I can see gas coming out of this hose. I had her at around 4500 rpms and to me she seem like she was not going very fast. The horn does beep once when I go to turn on the motor. I did remove the black plastic cover to clean out the box because it was full of dirt. When I took the boat out of the water and took her home to clean. I started the motor and the alarm did not beep like it did in the ocean. It did beep before I turned it on so it works I guess. The alarm just sound
