2006 2600SE Audible Alarm - Maxum Boat Owners Club

jdonz · 08-05-2009, 04:00 PM

Just got this boat, love it however last night when pulling up to the dock after a 30 minute run we got an audible alarm. We stopped for dinner and when we restarted the boat the alarm sounded again. We checked the engine oil level and it was fine and there were no other idicators other then this alarm. When we got to cruising speed the alarm stops but it starts back up once we drop below cruising speed or are idling. Thoughts. Only 30 hours on the engine.

check the drive oil reservoir......if that's low..the alarm will sound....

Thanks, would the alarm have gone off though when we went faster even if we didn't fill that? Another mention was an idle control motor? Stinks to have spent money on a new pre-owned and right back where I was when I sold the 93 one a month ago.

it could cause it to pressure to increase and the bottle to expand a hair.....might be the oil sender is corroded a bit too...clean that off...check the temp sensor connection...might be dirty there too....

filled drive oil res and alarm went off, ran for 20 min and then slow run for 20 and then ran for another 2 when pulling back into tte slip the alarm sounded again. Filled tank again and then did a 10 minute run and needed to add more. All said and done added nearly a full bottle does this sound about right or does it sound like there may be a leak.

Just find a mechanic to plug it into a diagnostic machine. My money's on the IAC motor. Should be about $100.

seapuppy · 08-06-2009, 04:29 PM

Wow..you put a whole bottle of gear oil into the reserv..?????...you have a leak my friend....either a bad seal down below or someplace else......but gear oil is pretty stable.....

Hey guys I am new to this forum?? My alarm is going off. Can anybody tell me where the sensors are to the temp,oil pressure and gear oil? I want to test each one by disconnecting to find the problem Thanks John

John welcome aboard.

FYI digging up an old thread usually results in less help as some folks are no long here, some sea puppy has passed away a few years back.

Anyhow what boat model and year do you have?
The lube reservoir is located on the front of the engine, plastic bottle and tends to be the number one cause of the alarm. Check the fluid level. The temp alarm sensor is mounted on the side of the t-stat housing, and the oil switch is located on the engine block just above the oil filter or it' s remove adaptor on the lower port aft side.

Mike

thanks for the help My boat is a 2006 SCR 5.0 Merc I will go today and pull each one. Temp is good and oil pressure is OK Hoping it's the gear oil reservoir Thanks again

FYI next to the temp and OP sensors are the ones for the gauges as well. The two temp ones look alike and the OP gauge is a big bell shape while the alarm sensor is smaller.

Disconnect one at a time to isolate. First verify lube level, sometimes is low but at rest does not cause a fault but then underway was the fluid sloshes around the alarm will trigger because the float drops from the fluid moving about.

Johnnyc · 08-12-2014, 03:24 PM

The reservoir was low I filled it and alarm did not go off Then I pulled the sensor from the oil pressure and it stopped Put it back on and all is good ??? Does it reset itself??
My oil pressure is around 50 at idle and around 80 at 2500 RPMs isn't that high???? it was always high even before the alarm sounded

Thanks for your help
John

mmwjr · 08-12-2014, 08:21 PM

Yes that pressure seems high so I might question the reading, either the gauge or sendor may be off.

The OP switch will reset if pressure is there.

What do you mean by pulled the sensor off, removed the wire and reinstalled or removed the sensor itself?

The wire could have had a loose or corroded.

Johnnyc · 08-12-2014, 09:15 PM

I just removed wire and replaced it It had a good connection???

mmwjr · 08-13-2014, 01:19 PM

So after you reinstalled the wire on the OP switch the alarm is no longer sounding, correct?

If correct than I must assume it did not have a good connection prior to removing the wire.

Johnnyc · 08-13-2014, 06:52 PM

No more alarm sounding I think it's OK ??????

Thanks for your help
