    Volvo Penta 5.0FIPNCSCE SLOW mode

    So I pretty much ran the engine there at the dock. I think the fuel is so bad in it it just eventually stopped sputtering and running when I got down to a quarter tank. Debating whether or not to drain it first or get some fresh stuff in there. When I changed filter the other day it smelled...

    Volvo Penta 5.0FIPNCSCE SLOW mode

    Didn’t know that! They only seem to have 89 but I’ll go lower octane then. Again, Ty for your guidance as it’s greatly appreciated

    Volvo Penta 5.0FIPNCSCE SLOW mode

    Well oddly enough I’m sitting at the dock and now the OTHER engine is running rough idle and the original is smooth. I swapped the coil from one engine to another, no difference. Temp good, oil good. I think it might just be older gas. It runs well then kind of jumps a bit. I’m running it...

    Volvo Penta 5.0FIPNCSCE SLOW mode

    Wait a second- The temp gauge wouldn't cause ECM to go nutty but a tach would? Who engineered this motor?!?! :D

    Volvo Penta 5.0FIPNCSCE SLOW mode

    I hear you, and that's exactly why I'm hesitant to start breaking things down and replacing air sensors, coils, wires, whatever because it could be something else entirely! I will add it's not just the RPM's all over at idle- After my last outing it first went into SLOW mode, though it also...

    Volvo Penta 5.0FIPNCSCE SLOW mode

    I didn't even think to check/replace the Ignition coil or the https://www.amazon.com/Volvo-Penta-3852217-Ignition-Coil/dp/B00OJ4KL5M https://www.napaonline.com/en/p/SME187492 I just have to figure out if I have both or one of these and where they are ha

    Volvo Penta 5.0FIPNCSCE SLOW mode

    I went to the marina and unplugged the breaker today and the rpms still jumped around. In addition the cooling system is all good per the gauges and temp gun. As I came back to the marina after SLOW mode started, the RPMS were still kind of all over. I'm wondering if it's that air sensor...

    Volvo Penta 5.0FIPNCSCE SLOW mode

    Their website is a little confusing. When you look under the picture it has the engine listed under it, if you click the wrong picture it takes you to the wrong place. For one it shows the engine as having a coolant system but mine clearly doesn't haha! When you clicked on fuel system, look...

    It's fuel injected, actually 5.0FI Volvo Penta.

    Volvo Penta 5.0FIPNCSCE SLOW mode

    Side thought- same gas in both engines and the other engine runs fine. The problems w the other engine seem to be intermittent. Not sure if and how that factors into fuel quality. ty captain!

    Volvo Penta 5.0FIPNCSCE SLOW mode

    Thank you, Dodge! I saw you give feedback to another member and was hoping you would weigh in! I still have half a tank of gas in there in a 75 gal tank. Should I add more fuel or try to have it drained first? Sounds expensive haha! Did you see my post about the Air Charge Sensor? What are...

    2004 5.0 OSI-EF not going over 3000 RPM

    I have 2 Penta 5.0fi. Oddly enough when I went into slow mode last night, the other one wouldn’t get above 3000 rpm’s, or it struggled to run at full capacity it seemed. I read through your checklist and didn’t see the impeller. I know they’re supposed to be changed every year. Just I didn't...

    Volvo Penta 5.0FIPNCSCE SLOW mode

    That's a good idea, I read something similar on another post where a boater was having a similar issue. I just ordered the sensor and itll be here next week. I'll go ahead and give that a try. The boat runs well for a trip around the lake and then it just goes into slow mode. Now it's...

    Volvo Penta 5.0FIPNCSCE SLOW mode

    So I disconnected the oil breaker and no change. Now maybe I'm thinking a bad Air Charge Temp Sensor? It runs rough at idle and always kind of has since I bought it. https://www.hardin-marine.com/p-23781-air-charge-temp-sensor-volvo-3854158.aspx

    2004 5.0 OSI-EF not going over 3000 RPM

    Did you replace your impeller this year? VOLVO has a good manual on how to make sure the cooling system is in tact. Cooling is one reason for SLOW mode.

    Volvo Penta 5.0FIPNCSCE SLOW mode

    That's what I was afraid of! The breaker is 170 dollars and there's no Sierra or other aftermarket part. I'll switch the port and starboard breakers to see if it has any effect before purchasing another at that price. It could still be a cooling issue for all I know in the end but the gauges...
