    MR outdrive - no reverse after changing lower shift cable

    And for those of you looking for actual advice and help as opposed to the “admiral’s” self-aggrandizing pay on the back, check the condition of the roller that slides into the shift fork on the cable when re-installing the outdrive.

    MR outdrive - no reverse after changing lower shift cable

    Yes. No reverse and engine dies when shifting into reverse. Even with the cable disconnected from the shift plate I cannot get reverse.

    MR outdrive - no reverse after changing lower shift cable

    If you mean the bell housing, yes. I made sure the outer cable was properly seated.

    Also, when shifting into reverse with the engine running it triggers the shift interrupt switch

    MR outdrive - no reverse after changing lower shift cable

    Replaced lower shift cable. Now can’t get into reverse. Any ideas of what to look for? I dread having to pull the drive again.

    Mercruiser 140, MR outdrive - unidentified fastener

    U-joint bellows. I guess it’s like a prize in a box of cereal. As long as it’s not supposed to be in there, I won’t put it back. Thanks very much for the replies.

    I pulled the outdrive to replace bellows and this nut fell out. Any ideas what it is and where it goes?

    Problem Restarting, Idling and Acceleration when the engine is warm. Merc 140hp 3.0 Alpha 1 Gen 1.

    Here is what the filter looks like. It is inside the pickup tube. You have to unscrew the pickup tube from that junction block to find it. (Ignore the rubber hose and cap in this pic. It was from pressure testing the unit for a possible air leak.)

    Problem Restarting, Idling and Acceleration when the engine is warm. Merc 140hp 3.0 Alpha 1 Gen 1.

    Make sure to check the small filter inside the fuel pick up tube inside the fuel tank. I had a similar situation on a ‘85 Merc 140 where it acted like valor lock but was actually debris from inside the fuel tank getting sucked into that small wire mesh filter. I’ll try find a picture. When the...

    Fuel pressure loss on Mercruiser 140

    UPDATE: I feel like an idiot. Took the boat out yesterday and still had the same problem. Today, I took the fuel gauge sending unit out. I had taken it out a few years ago to fix a leaky gasket and I used plain old RTV to make a new gasket. RTV is apparently NOT impervious to gasoline. It has...

    Fuel pressure loss on Mercruiser 140

    I pulled the pickup out of the tank. Sealed up the bottom end put a short piece of hose on the barb end. Then put under water with air hose to pressurize. No leaks. Figured I’d start there and work my way back. Checked and rechecked all hose ends and connections. The PO had the pickup barb...
