    Volvo Penta AQ131A & 275 OutDrive

    I was just wondering what problems these engines have. My issue with my boat is not with the water neck and my guess is the original poster doesn’t have this problem either. I am pretty confident he has a warpped head and or bad head gasket along with a clogged heat exchanger core.

    Volvo Penta AQ131A & 275 OutDrive

    What kind of issues did these engines have? I don’t know anything about their history other than the Volvo guys love them and boost the crap out of them and the ones in these boats are severely under powered.

    Volvo Penta AQ131A & 275 OutDrive

    I look forward to hearing about your progress. What is your plan with the boat? If you plan to get it running and want to use it and you have it out of the boat already I wouldn’t bother compression testing it. You will have to rig up a way to start it, get water to it etc and it’s not worth...

    Volvo Penta AQ131A & 275 OutDrive

    I have the same engine and have posted here as well. (You can find my threads by looking for overheating Volvo Penta 230b) I had/have 2 threads going and I haven’t found a fix. Biggest head scratcher I have encountered and I have fixed or replaced everything but the heat exchanger. The...

    Volvo Penta 2.3L AQ131 runs better with timing advanced

    Good idea. I will check that. I did think this was a full 12v to the coil system all the time but that is from memory and that only gets worse each day!

    Volvo Penta 2.3L AQ131 runs better with timing advanced

    I triple checked. I was responding while this post appeared and explained it below. I didn’t line up the marks on the belt because well rules are for others and not for me! :) Thank you for the electronic ignition part number. I was looking to do that next year. Just trying to make sure...

    Volvo Penta 2.3L AQ131 runs better with timing advanced

    Not sure about the cylinder heads being a common problem. Mine was resurfaced just last week because it was a bit out of shape from a severe overheat from the person I bought it from. I am sure I am not off by a tooth. I triple checked. Only noticing because when I got the boat it was...

    Volvo Penta 2.3L AQ131 runs better with timing advanced

    I know when I was messing with the distributor when I forgot my timing light I could definitely hear ping then I backed it off and it went away. I can hear my Buell ping on hot days. Plus you lose a ton of power. The dwell is perfect at 61 degrees….which I think is high personally. The thing...

    Volvo Penta 2.3L AQ131 runs better with timing advanced

    I have been fighting an overheating problem and have given up, just going to run it until melt down. However, I noticed tonight that the boat runs way better with the timing advanced a bit. It’s starts easier both cold and hot, idles much smoother, comes out of the hole without hesitation, runs...

    1992 Volvo Penta 230 with SPA-1 Overheating

    Been out for a bit. Tried the sniffer and it did not detect combustion gas in the heat exhchanger. I removed the head again. Brought it to two cylinder head shops both said it was fine. I had it cleaned up anyway as it was out about .003” in the center. Tried it again and it is still...

    Will be trying the gas test tonight. Picked up a kit this weekend. I will report back.

    1992 Volvo Penta 230 with SPA-1 Overheating

    Swapped the thermostat. I haven’t swapped the heat exchanger cap yet. It does release pressure, even days after running, when opened. It doesn’t boil over, but maybe I will get a new cap. Thanks!

    1992 Volvo Penta 230 with SPA-1 Overheating

    Well the engine is from the 70’s. Don’t know about the outdrive. Their seatbelts are wonderful I suppose. I do understand this is supposed to be a pretty rugged setup. IDK…They run hot from the factory which doesn’t leave much head room for small problems.

    1992 Volvo Penta 230 with SPA-1 Overheating

    Agreed on the water flow. Replaced both pumps already. I am stuck on the exhaust. I really think at high rpm the raw water can’t get out. To be fair I don’t understand how the exhaust bypass and exhaust tube work. Unfortunately, I will have to pull the engine and the lower unit again to...
