We went for a great ride here in Central NY, Colors were just beautiful. Headed east went through Lock 23 on the Oneida River out to Oneida Lake. About 1 1/2 hr. to the lake. Got to the middle of lake and had lunch. On the way back about 1/4 mile from the marina the engine alarm went off (same problem summer of 2006). We turned off the Port engine and turned it back on and the alarm stoped. Last year we had the impellors changed and the problem stoped so we though the problem was corrected. Oil and water temp are good. We have also changed the fuel filters, oil filters and Oil.

Does anyone have any idea what the problem could be:smt013
 
Could you have picked something up blocking your intake? Were temps spot on or slightly higher?
 
I assume you have a systems monitor at the helm/dash...which tells you which system is causing the alarm?
 
Nehalennia, the port engine has always been 5 - 10 degrees higher then the st. engine since we purchased it in 5/2007
 
Consider purchasing a heat gun to shoot on the engine(s) the next time this happens.
 
The sensors for the gauges are different from those for the alarm.

Check the alarm sensors.

Mine has a loose fitting on the oil pressure connection that caused intermittent alarms, even though the gauge was happy. A new connector and everything is fine.
 
"The sensors for the gauges are different from those for the alarm."

Correct, but he said he heard the alarm go off.

On our boat, both sensors are on the thermostat. I had to replace one of the system monitor ones this year. The alram kept comign on and would not go off. I swaped them and the problem was resolved, so I knew we needed a new one.

The originals are no longer manufactured. I have what sea ray says should work. Unfortunately I will never know unless the engine overheats, so I try to trust the gauges more and put a heat gun on them every so often.
 
Connie, the problem is probably transmission temp. I had mine go off one time after about three hours at 22knot cruise. The trans does not have a gauge or a light on the systems monitor, just the alarm. It took me a while to figure out what the alarm was. After I realized it was the trans I put the engine in neutral and ran it at 2000rpm to get plenty of cool water running thru it while it wasn't under any load. It took about 1 min before the alarm stopped sounding and the trans cooled down. The problem ended up being the engine alignment was off just enough to create some heat that built up if I was on a long enough cruise. Since the alignment was reset it's been fine. Mark

I am curious, how did you or a mechanic figure this one out?
 
Greg, through process of elimination, nothing else was wrong until we checked the alignment. I was told by a mechanic that it's not that uncommon for alignment issues to cause the problem I had. I think Sea Ray should have a better way of monitoring transmission temps (a gauge would be nice). If I remember correctly my 370DB at least had lights on the systems monitor for the transmission temp but my 370DA only has the alarm. It was very difficult to figure out where the alarm sound was coming from when it happened. My engine gauges were all reading normal so I started to shut down my electronics one by one but the alarm didn't stop until I shut down one of the engines. At that point I pulled out my owners manuel and realized the alarm is connected to oil pressure, engine temp, and trans temp. The oil pressure and engine temp where fine so I knew it was the trans. I hope this all makes sense to you, you probably have the same set up on your boat. Mark
 
Our systems monitor has a light for transmission. Wonder why they got rid of this in your 98 model?
