    OMC stringer thump sound from the rear.

    I cannot raise it or lower it, but the forcaes under water may be stronger than I am. It is more like some play it has. Here is a video of the play I’m talking about. I will try tightening the screw.

    OMC stringer thump sound from the rear.

    Thanks Kenny. Yes, my original thought was that the tilt clutch is allowing some slip and letting the complete drive raise and then come back down. I rebuilt the tilt clutch packs 2 years ago and everything has been working as far and up/down motion. I also thought that maybe the Allen head...

    OMC stringer thump sound from the rear.

    I cannot edit the post anymore, but here is the lower drive drain plug removed after about 3-4 hours or usage time. The drain plug went in clean the other day when I added new fluid.

    OMC stringer thump sound from the rear.

    I have heard a thumping noise from the rear and I think I felt it too. It’s only happened 3 times and it happens fast enough to where I can’t pinpoint what’s really going on. Best I can describe it as is: The thump/feel feels like when you’re lowering/tilting the drive into position until you...

    OMC 3.8l dying at high rpm and weird cranking issue.

    I feel it ran a bit better today, but it may have been a placebo effect. Got up to 3k rpm on plane and it was fine. Wanted to go a bit faster so I went up to 3400/3500 rpm and a few seconds later it died. It starts back up and gets to 3k rpm no problem. 3k rpm feels decently quick, no real...

    OMC 3.8l dying at high rpm and weird cranking issue.

    New fuel pump installed. I noticed the fuel line was a bit stressed when the trim was up, so I re-routed it. Made sure all dist wires where seated. The wire from coil to cap appeared to be loose/have a poor connection at the coil. New battery terminal installed and grounds cleaned...

    OMC 3.8l dying at high rpm and weird cranking issue.

    I found this one. https://www.ebay.com/itm/353230954261?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=3a7l1vf6svi&sssrc=2349624&ssuid=zsUQ7sCKS_6&var=&widget_ver=artemis&media=COPY

    Yes thank you. I am going to just permanently hard wire those 2 connectors this week.

    OMC 3.8l dying at high rpm and weird cranking issue.

    I’m going to get a new battery cable terminal for it and clean the ground wires. Oil pressure switch? I thought it was just a pump and wiring. Where can I find a new pump for $45? Do you know what year and model of truck has a pump that I could get from an auto parts store? 3.8 liter v6 GM.

    Missing exhaust flapper?

    I’ve just read another thread here from a member, where a missing exhaust flap have issues. I see nothing that resembles a flapper on my drive nor in the manual. But I’m curious if it’s needed or used? It’s a 1984 OMC 3.8L V6 stringer sterndrive. Thanks.

    OMC 3.8l dying at high rpm and weird cranking issue.

    Thanks. I hadn’t heard of oil on the flare fittings. I applied sealant on the threads and oil on any flare fittings between the separator and carburetor. Short story. Cranking issue may be due to a loose + battery cable. Engine died on the way back to the dock. Wired in electric fuel pump and...

    OMC Stringer ESA not working-Adapter housing not centering.

    Took it out today. Shifting was a lot better. The ESA did not want to work this morning though. I pulled the wires with pins out of their boots and connected the wires and all went well today. Shifting in and out of gears smooth. I felt 1 clunk from the rear when the boat died towards the end...

    OMC 3.8l dying at high rpm and weird cranking issue.

    Ok thanks. I am going to check those lines and maybe use some Teflon paste on them.

    OMC 3.8l dying at high rpm and weird cranking issue.

    It was 1 solid hose. The only lines I have not serviced are the hard lines. Hard line from separator to pump and pump to carb line. They are all tight. Would an air leak in those cause issues?

    OMC 3.8l dying at high rpm and weird cranking issue.

    I don’t understand how or from where. It was a line attached to the water separator and directly into a fuel can. Do I need one of those hand pumps that pumps fuel From the tank?

    OMC 3.8l dying at high rpm and weird cranking issue.

    I hooked up a clear hose to the pump and ran it to a 1gallon fuel tank. Here’s how the fuel flow looks. Is it normal to have air pockets in the line? If it’s not normal, is the pump bad or how do I get rid of the air pockets? It idled for about 10 min and then 5 min at 2K rpm and the flow...

    OMC 3.8l dying at high rpm and weird cranking issue.

    What do you mean a lot of media? I ordered this one. Does it look good? FRAM G3 In-Line Fuel Filter https://a.co/d/cyTXe6i That is fresh fuel in the tank. No strainer in sight. So adding the fuel filter. Is the engine starting issue just something normal that I have to deal with then?

    OMC 3.8l dying at high rpm and weird cranking issue.

    I removed the tank and the pick up tube cannot come out. I was able to look inside the tank a bit with my camera. The pick up tube does not have a a screen on the bottom. I stuck a 1/4” wire down the tube and it was free of any other blockage. I can’t get the last piece of rtv out of the anti...
