2000 AC 500 issue

Recommended Posts

My 2000 AC 500 started acting up today on the lake, first on the tailer it started fine and ran for a while then killed for no reason, finally got it going again then ran fine the rest of the time until on the way into shore we were going along it started making a popping sound and eventually killed, couldn't get it going again so we pushed it for a while, then it started again and ran fine all the way to shore, then started popping again and killed. Got it going again and while idiling it killed. What would cause this? I pulled the plug and it looked fine, would it a bad coil or carb issue or both? It has plenty of power. I replaced the plug and it still does the same as above.

Sounds to me like bad gas. Perhaps you have water in it. Try adding some seafoam to the tank. May take a while for it to work through the system though.

have you changed your fuel filter recently? This would be a good time to do it. Also, I believe that model has a fuel selector switch with reserve right? Try putting it on reserve (regardless of how much fuel is actually in the tank). The pickup is more toward the bottom of the tank and perhaps that will make a difference.

My old man has had some problems with fuel lines and the connections. They would leak, not so much that you would leak gas out, but that air would get in and it would lose vacuum. He replaced all fuel lines and went with some steel threaded cable clamps (along with replacing fuel filter) and no issues since.

Thanks for the advice, I will try the above mentioned and replace the plug. I will replace the fuel filter as well. It is getting low on gas, so I will top it off with some 91 octane and add seafoam and see what happens, I just don't want to get stranded on the lake and have to push it again so I will do some test runs at home first and see how it acts before I bring it in for service. It does have the reserve selector on it as well.

    • Heavy rains across northwestern Wisconsin last weekend and early this week have flooded some roads and caused washouts on some highways, roads, state parks, forests and trails. According to the National Weather Service the area has received 7 to 12 inches of rain from Friday through Monday.Several park system property or portions of properties are closed due flooding. Amnicon Falls State Park, closed temporarily but has reopened, though some roads, trails and observation areas remain closed. Pattison State Park is open for camping only; all trails, observation areas, picnic and day-use areas are closed. There are washouts on the dam that forms Interfalls Lake and Highway 35 over the dam is closed. A campground and horse trail are closed at Governor Knowles State Forest and the day use areas along the river at Interstate Park are underwater.Water was roaring over Little Manitou Falls at Pattison State Park.Photo credit: Gervase ThompsonAll rivers in the region are running extremely high. The falls at both Amnicon and Pattison are roaring, but road closures mean observing the falls now is challenging. The Bois Brule and Flambeau rivers are high enough that some canoe launches and campsites are underwater. The water is making its way downstream and the Lower Wisconsin River is running very high with all sandbars submerged and canoeing and kayaking not recommended. The river is expected to crest Muscoda this weekend at 40,000 cubic feet per second. .
    • I'm still going to smoke this fatty while camping this weekend whether Leech likes it or not.....😋       See you fellers on Monday........
    • Rick didn't like all the "My Grills bigger and better then yours" posts!  😅
    • We switched to a new server. Had a glitch in our dB that lost a couple days of posts.
    • I ripped a hole in one of my favorite pairs of fishing shorts just need a decent sized patch to cover her up
    • I am not sure what happened either but we lost all of the posts last couple days not just this thread. And it looks like the same thing happened over on FM site as well. I know the site was down last night while I tried look at it.
    • We had no problems but only brought 10 extra gallons over.  We fished 5 days, pretty much running wherever we wanted and ended with 7 gallons remaining in the boat.  So, we burned 30 gallons of fuel in a 1785 Lund with 90 hp Mercury 4 stroke.   I thought that was pretty good!
    • Seems to me that we are missing an entire page from this thread that was here yesterday.... what gives?
