Volvo Penta 5.7 , 300 engine code issue

[Regal35sc]

Hello All,
I just bought a 2016 boat with twin Volvo Penta 300 5.7’s. About 30 seconds after getting on plane My port engine codes out with check engine. Oil pressure is fine, temp is fine, oil dipstick reads in the right zone. Checked the paper oil filter container first time and saw the top was leaking a little. Fixed that and ran it in neutral at dock. Brought the rpm’s yo to 3700 for one minute. Oil pressure was 68-78 PSI on port and 58-70 on Starboard. No codes. Took her out got on plane and coded out again once under load. I noticed when I got it back that the oil canister on The starboard side once opened was 1/2 full of oil which I would expect. The port side however was empty. Oils are running through as the filter is wet but...( is this normal) anyone have ANY clue as to WTH is coding me out. This time of year I can’t get anyone to come out soon to connect computer to it. I feel like it’s something minor but I don’t know. Oil pressure from one engine to the other have been averaging 10 psi difference since I got the boat. Any input would be great. First time on this forum. So far good info

What is the temp running?

Check the oil pressure switch too

 

[Regal35sc]

Temps are both around 165 at 3700. How would I check oil pressure switch?

 

[Scott Danforth]

With a pressure source and a volt/ohm meter

 

[Regal35sc]

Ok. Thanks. I will try that. You think it would still show the oil pressure changing as the engine runs even with a bad pressure switch?

 

[Scott Danforth]

your gauges run on a different sensor than your ECM. you should have two gauge senders and an oil pressure switch.

I don't think this is true for this engine. But can't be sure what version of 5.7 Regal35sc has. would need a serial number to be sure.

I don't understand what you mean by "code out" .
Are you getting a warning horn?
Is it a "soft" or "hard" warning?
Is the engine going into "power derate" or "low rev limit"?

Please don't run your engine at 3700rpm with no load, it's pretty hard on the engine and doesn't really serve much in the way of diagnosis.

The amount of oil in the filter housing has a lot to do with how long the engine was shut down and engine oil temperature. Don't think that has anything to do with your "coding out" nor should the difference in oil pressure between the two engines. But both should be looked into once the MIL light and/or warning horn is taken care of.

Welcome to the forum, we will try to help. But we do need to know which Volvo Penta 300 5.7 you have and a more precise description of the way the engine operates.

I am not sure which engines they are I will get serial numbers for help ( thank you) both engines were down for 25 hours but showed different levels which made me question. I wouldn’t typically run the engines that high was just trying to see if it would code out ( beep , showed check engine on both The tach gauge and ecm. Once I went to neutral the beep stopped and reset I imagine. The check engine symbol stayed on on the ecm display but not tach. Not sure which it is going into power derate or low rev. As soon as the alarm sounded I backed off and put in neatral afraid to damage anything. Obviously the motor is ina regal 35 sport coupe. Not sure if that helps at all

If your your boat was registered, a hull number will allow me to see exactly what you have. A picture of the dash will also help with what displays you have that might be able show any codes.

Regal is a a high quality boat so the chances are good that this might be a DIY fix.

 

[Regal35sc]

Tried to upload By pics but wouldn’t allow me but the symbol on the tach was a triangle with a question mark saying che k engine. On the ecm it said check engine also but after clearing it showed a little engine block pic like a car. The hull number is RGMVH245F516. Much appreciated also good to hear they are quality boats. That was what I had thought also

 

[Regal35sc]

Not sure y those loaded lok

I have basically the same engine . Mine is a 2011 5.7 300 C. These engines are a nightmare of electronics, I had a lot of trouble getting mine repaired. It sat a the dealer for over 90 days. I bought a Rinda Diacom and finally repaired the boat myself. It was the best 700.00$ spent. If you take it to a dealer they will charge 500 just to hook it up to their Rinda. I still get a long term fuel failure code that derates the engine 2500 rpm. I reset the alarm, and it runs for about 3 days, The days of the carburetor were so much more reliable. There are hundreds of alarms possible, you need to find out which one. I wish you were close, I could at least tell you what you have. Dave -R

 

[Regal35sc]

Just got her so it’s frustrating that I can’t really see what she’s able to do. Thanks for all the help guys. It’s much appreciated

The hull number RGMVH245F516 doesn't come up as registered on the Volvo Penta network.
I have run into this a few times. It's possible the dealer that sold it to the first owner didn't get everything right.
Gonna need the serial number off of an engine, drive or TSK.
There are some Quality Campaigns going on with these engines.

http://www.volvopenta.com/easyconnect might be something other than Diacom.

Thank you for your help. I will get serial # today

Your engines are V8-300-CE-B and you have EVC control Ver. E2
Have you had the Volvo registration transferred to your name? This is something you really should do. There is some warranty coverage that runs until 2020
There are no open campaigns for your motors.
Earlier you posted that you saw "triangle with a question mark" is it possible that was a exclamation point instead of a question mark?
You also posted "On the ecm it said check engine". The ECM is mounted on the engine, so I don't think that's what you were looking at. Can you look in your operators manual? It will list all the displays that your boat could have. We need to know what display you have so we can see if any fault codes can be accessed.

If you had both the engine block and triangle with exclamation point while in RPM reduction mode. That's a pretty serious fault and should be addressed before using the boat again.

I highly recommend that you talk to a Volvo dealer and have them look at it! That's a very nice boat you have and I think you will be real happy with it once the problems are worked out.

I'm happy to help any way I can.

Thank you. So I ran it today to verify. It did not go into rpm reduction mode as I first thought. it did show an exclamation point ( sorry for the misrepresentation) it is only the port side engine. I have a video of us starting at low speed to getting on plane. Can’t load. It takes approx 1 min on plane to beep. It is one beep. I backed it down then went up in rpm for a short test to see if it went into low rpm and that did not happen. It beeped again so I went to idle then neutral. Checked everything in the Bilge. Engines perform perfect and seem to be in synch. No leaks. No strange sounds. idle is dead on. Psi seems ok. At the cockpit there was a faint smell of plastic or similar when it beeped. Not underneath where engines are and it went away instantly when we stopped ( voltage on both batteries read 14.3 ) . As far as ecm I guess I was thinking the ecm is the small display under the rpm bezel that shows coolant temp, voltage , oil psi,fuel percentage and a couple other items. There it shows the small triangle/exclamation icon. In the rpm bezel it shows the same. A little baffled. I truly appreciate your knowledge as you seem to know quite a bit about it. I’m hoping to be able to trouble shoot it soon. Hard pressed to get any calls back nm someone to come put a computer on it
