Are or aren't large enough?

you said are?

Aren't large enough(my bad, I have fat fingers and don't always type everything out right).

lol ok thx.

Does anyone know what the warning sounds mean, long steady beep and short beeps.

From the sounds of it you either have a 95 or older, or somebody used the system check to old style conversion harness(96+ used a system check guage that had individual warning lights to tell you what the alarm was for). With the old style system you would get a solid horn for overheat while it was overheating, a solid horn when the fuel restriction sensor was tripped(would stop once the fuel restriction was no longer present), and I believe a beeping horn for low or no oil.

the boat is a 87 with a 96 johnson 200 on it so the CC is 87 and has no warning lights, just a loud high piched beep sound for the alarm.

On my Mercury the warning horn is tied into the low or no oil. Since I removed the oil inject you have to clip the wiring that goes to that sensor. For me the best answer was to install a water temp gauge.

If you turn the key on but not start the motor, if the beep is going off look for the low or no oil sensor and pull that wire.
