I am a bit new to the boating world and recently purchased a 2002 25 Outlaw. So far the boat has been great, but yesterday we were out on the lake and when i went to start the boat back up a alarm went off. (beep...beep....beep) I checked all of the gauges and everything look fine. I found that the alarm went off when i gave it one or two clicks of throttle. (a few hundred more revs) When i was coming in the marina i noticed that the water temperature was 190 degrees. This boat normally runs in the 170 range.

Any thoughts on why this alarm is going off? Are these issues related. The boat has 200 hours on it and just got a new belt and a water impeller.

I am going to check the coolant level today the boat was obviously hot and it was also raining at the time.

Thanks

i would check your trim fluid if its a little low it will trip the alram. As for the temp mine was runnin a little hot this weekend too might due to the 100 plus weather not sure though.

Drive fluid level will also alarm so check that also.

Water pressure will also cause this. If your housing is wore on the fresh water pump and isn't moving enough water...Impellers go bad if you get into sand or suck in something abrasive. Might want to look there as well if it was running cooler then suddenly jumped up.

check fluilds. thats a good place to start. mine was running around 190 this weekend as well. its because of the 100 degree weather and the 85 degree water. when you start going over 190 is when i would say there is a problem. good luck on stopping the very annoying beeping.

or pieces of the old impeller in the oil cooler

drive fluid, oil pressure, and temp can all make your alarm sound.

Make sure its not your depth sounder..I've seen stranger things happen...what engine is in your boat?

Is has a 496 mag in it. Thanks for the advise. I am going to just drain the drive oil as well as check the level.

Oil pressure looked normal.

Any other ideas please fire away.

Thanks

Well..496 mag is closed cooling..it should not run hotter than 175*..really ever...fluids..also check heat exchanger for any impeller debris..those older engines would catch impeller pieces in there..the newer ones have an open center so the impeller pieces can pass through...make sure on the depth sounder thing..I have seen it happen before.

I think the alarm goes off at 190* or 200* , so that would be about where you were at there...
