Warning sound

I finaly got my boat in the water today and took her for a test drive and she hauled a$$, got on plane real quick and motor ran great, but the entire time the damn warning sound where the key goes was going off, I noticed when I trimed the motor up it would go off for a few seconds then come back on, I checked and the motor was pissing a good stream from the water pump.
Could it be the fact I was using a old plastic gas tank, and maybe the pressure wasn't good enough?

sorry for the noob questions.

One more thing the throttle linkage is terrible, almost all the way foreward and barely any increse in gas, then it's stiff and you have about one inch and that is where if u push hard it's a major increse.
All the way back and had no throttle for reverse, but she shifted in gear just no throttle.
 
are you using the oil injection or premixing? was it a steady beep or an intermitent? do you have a temp or water pressure gauge?

the other sounds like cable issues, either adjustment or replacing the cables.
 
I am premixing, and when it went off it was a long steady beep.
The only gauges I have are fuel, rpm, volt and a picture of a boat that looks like it isn't on plane yet. and a hole where my speedometer goes.
 
sounds like it is the overheat horn, but one of the omc gurus will give you a better opinion. how long did you run it with the horn going off? might want to plan on a water pump and t stats in the future.

on a side note, looks like we're gonna get a blow in the gulf, time to start getting the generators running and pick up the yard furniture.

Hey guys,... be careful down there....Move the important things indoors, or under a shelter... You know,... like boats and trailers.... The rest of the things can stay outside.

I ran it for about a hr, but the water pump was working fine, It had a steady stream of water coming out the motor.

Can anyone else think of any reason this would be happening?

Ohh and what is a t stat?
thermostat?
 
jdog you can ck the thermostats real easy. they are up abouve the spark plug. it is a 13/16 scocket just like the spark plug.take the blace plastic plug out,then the spring then the thermostat. make sure there is no blockage,silt or sand were the thermostat is also ck thermostat to make no slit or sand has it blocked.

This applies to the OLD cross flow V-6's, not the new style loopers. And just because it is pumping doesn't mean it is cooling. You could have a stuck T-stat, a bad poppit, or sand or silt blockages inside the engine. Also the water pumps in the 93+ style 200/225's MUST be in TOP shape for the cooling system to work properly. They work off of pressure, and if tehy don't get enough pressure they WILL overheat(they need about 13PSI or more to open the poppits and cool at speed). And if it seems to happen as your hitting teh throttle, theres a good chance it is fuel restriction causing it to go off. Most importantly, DO NOT RUN IT WITH A HORN GOING OFF! If it is fuel restriction you can lean it out and melt a piston in a HURRY. If it is an overheat you can lock it up QUICK, and if it has oil injection it could not be oiling. Unless you know the horn is a false alarm, DON'T RUN IT WITH IT GOING OFF(unless you like wasting $2500 for another powerhead). These big V-6's are NOT forgiving to overheat or lean out.
 
whoa, ok im officialy crapping in my pants, but thanks for the info. maybe I should take it to a marine mechanic for this issue, but if it's fuel restriction, whitch it could be due to the fact that im using a test gas tank that the guy i baught it from had it hooked up to. he said the real tank has just been cleaned and drained but the hose to hook it up is just sitting where all the cables come out and inside the box i see the fuel/water seperator, I wanted to change that filter before i hooked up the real gas tank.

thx for all the info.
 
If the alrm stops soon after letting out of the throttle, then it is probably the fuel restriction alarm setting it off. The fittings on portable tanks are really large enough to supply 20-22 gallons per of fuel which is what that 200 will drink if you open it up. Find out why the alarm is going off first thing though as running with the alarm going off is just begging for trouble.
 
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.
