Warning sound

[phatdaddy]

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.
