Hi Everybody, My nephew has a 2012 Chriscraft with a 2012 Volvo 5.7L 320hp duoprop. An Alarm sounds randomly above 3500 rpm. If he backs off to 2500 rpm the alarm stops. If he goes back above 3500 rpm it may be fine, or it could alarm again. All his guages are reading normally when this occurs. He's had it to the dealer 2x and the dealer hasn't been able to identify a problem. Are there any Volvo owners who have experienced similar problems? I haven't been on the boat so I have no first hand knowledge. He says there is no pattern in the alarm. It just sounds off. He purchased the boat new, and takes pretty good care of it. It's always been dealer serviced.

Is he sure it's an engine alarm and not an alarm from a depth finder catching some turbulence?

My Admiral & kids sound a similar alarm when I bring the engines near or even above 3500 RPM. things tend to quiet back down once I lower the RPM to under 3000. laugh

Is this a fuel injected engine or carburated? As that would tend to make a difference . . . I assume fuel injected, but wanted to check.

Anything unusual about the gauges (temp, oil, etc) when this happens?

Hi, thank you for the replies.

KDL, when I see him I will have to ask him about the depth alarm. I don't recall if his boat came with a depthfinder, or he mounted one. At this time of the year all of us northeast boaters are out of the water so it will be spring before he'll be able to compare the sound of the depth alarm.

tpenfield, The guages all read normal when this occurs. The engine is fuel injected.

I don't think he's speaking about is "admiral".

Catalytic converter version . . . probably . . . I have come across some discussion about an exhaust sensor on the Volvos that sometimes gives false readings and sounds the alarm . . . but I would not go on a sensor hunt at this point, because it can get expensive. the problem with the fuel injected engines is that you need to hook them up to a computer in order to get any decent information out of them. Too many sensors and variables to do guesswork.

Spoke to my nephew. It is definitely an engine alarm. There is a dispaly that says "engine status" and a red light turns on. He said he doesn't know if the engine is equipped with a catalytic converter. Actually took a short movie with is iPhone.

OH! I forgot to mention that the light does flash in any sequence so it provides no clue as to what the problem might be. it is simply a solid on.

Not a lot to go on . . .

5.7 Fuel injected engine
Alarm is speed (RPM) sensitive 2500/3500
Oil and Temp are within acceptable ranges

Your nephew may want to check over at the MarineEngine.com web forums or possibly the iBoats forums. Not many V-P guru's around, but they are probably at those places.

Is he not wanting to have a dealer/shop look at it? (that approach can get expensive)

An alternative would be to get the Rinda/Diacom software ($500 ish) and take the DIY approach. Probably pay for itself by avoiding a trip to the dealer/shop.

The V6's in my Regal have temp sensors in each exhaust manifold (the one digs a hole in my arm when pulling the riser plug)-- so I'm assuming they may play into the alarm- ergo, has the nephew checked the riser temps while warmed up to see if one's hotter than the other? If so, could be a water flow issue. If not, could be a bad sensor or loose wire to them, or other sensors... (I never trust mechanics to check everything)

Yes, to FR's point, I think that is the most probable issue, without any diagnostic tools . . . either the sensor is flakey or the fact that the exhaust riser is getting too hot. Knowing the exact engine model would help.

Tpenfield, he's had boat to the dealer twice, so it's already cost him money. FR that's a good tip. I'll pass it and the website suggestions along to him. I'm curious, are the temperature sensors in the exhaust manifold associated with catalytic converter models or are they Volvo specific?


Thanks again

It is amazing that the dealer(s) cannot fix these sorts of things. It seems that the EFI/MPI engines have a mind of their own . . .

I'm not sure if the exhaust sensors are temperature or O2 . . . maybe if can get the exact model number of the engine, that might help.
