Well today me and my bro took the boat out, and about 2 minutes into the ride we started hearing a loud constant beep. I throttled down, took the manual out and it shows that if that beep occurs it could either be the intake grates clogged, or the engines overheating. I started the boat back up and slowly took off making sure a steady stream came out of the 2 holes on the back of the boat. I read sometime in the past that if water is coming through those small holes then the engines are not overheating...I jumped out felt and tried to look to see the intake grates, didnt feel anything in there...So we continued to ride around that immediate area..Every 2 minutes or so I would stop and the beep would still be there, so after about 30 minutes I decided to head back in...Got the boat back up on the trailer and got under it and could see the impellers fine, nothing in them at all...30 minutes after the boat had been off I got home and put the lanyard back on and it still did the steady long continuous beep...I need help!!!!!!!!1

Look in the engine compartment--- at the top of the engine. Notice 2 black hoses and an arrow on each head. One point to teh engine, the other away from the engine. The hose coming into the engine should come from the pump housing, thru the transom. This is the water intake the manual speaks of. There are holes inside the pump where the impeller actually forces water up through them into the engine, like a water pump. The other hose, leaving the engine, goes to the flush fittings on the transom and the top of the engine compartment. Using these fittings "backflushes" the engine. Try to flush the cooling system and see if it cures your problem. Or, disconnect each intake hose from the head and try to flush water through them. The water should come out the pump nozzle. If not, it is clogged. Let me know. If you try to flush with the water hose, remember to crank the engine first and then turn on your water.

so while i am flushing water through the engines they need to be running? do one at a time?

by the way, when i got home earlier i put the lanyard on and it did the regular 2 short beeps...maybe no problem now?

[tiggerman]

Yep, one at a time. No need for both at the same time. Running just one lets you hear noises that are unique to each engine if there are any. Any time you hook the hose up to the engine to run water through it, the engine needs to be running.

well i flushed both engines, i didnt want to let them run too long, did one at a time, and they seem fine...guess i will find out when i actually put it in the water again!

If you hooked up the hose to the flush fitting and cranked her up and ran water thru it, you should have seen water coming from the pump outlet thru the nozzle. That would tell you that you had water flow and no obstruction....

oh yes there was plenty of water coming out on each side when i did them...so maybe it was something else that caused it? maybe freak accident? maybe it wont happen again i hope!

[tiggerman]

Hope ya got it covered. It could have been trash in the intake hole.....

well, today we took the boat out, wanted to test everything out since next week we are going to florida with it...for a while it still did the continuous beep, but i decided to drive it more anyway and it stopped eventually, we rode around for about an hour or so, so i figure if anything bad was happening it would have already happened, maybe some sort of false alarm?

[tiggerman]

Did it start immediately or after you ran it a while?

it started immediately, then after we ran it a while it stopped...

[tiggerman]

Sounds like the temp sensor in the head has taken ill....It could be either engine, though. When running, unplug one, then the other to see if it stops. If the noise started immediately, chances are it's not overheating. If water is flowing from where it is supposed to flow, its probably OK.
