    93' OMC 5.0 EFI - Struggling with hot starts, sagging drive and overheating at idle.

    Open the throttle a bit next time it has a hot start problem. If it starts easily, check the resistance of the ECT (Engine Coolant Temperature) sensor- if the resistance is too high, the ECM will deliver more fuel than needed because the resistance and temerature have an inverse relationship...

    Rough and stalling idle. Repeatedly stalls when prop is engaged.

    Take a fuel sample. Loosen the fuel fill cap- if it wants to run, it could be a clogged vent line. If possible, use a fuel tank for an outboard and if it runs better, find out why. How did you set the idle screws at point 9 turns, by eye? Has anything else changed since last year?

    Long steady beep 1999 Mercury 115

    Assuming this has a sensor in the oil reservoir, did you check that?

    mercruiser shift cable install tool to help it tthru the bellow

    You can also push the tips of needle nose pliers in (make sure it's smooth), to stretch the opening a bit. That alone makes it easy to insert the end of the cable- that's how I did it. Once it has been passed through, the ring is crimped and it seals.

    Mercruiser 4.3L Battery Cable Lengths & AWG Sizes?

    If it's intermittent, do a wiggle test. Best to only create one thread. Can you post a photo of the starter- the old style didn't use gear reduction and the new ones do- they need less current, although they still need a lot. Do you have jumper cables? You can use those to bypass the existing...

    Mercruiser 4.3L Battery Cable Lengths & AWG Sizes?

    Is it cranking slowly, or taking a long time to start with normal cranking speed? You should be able to have the starter tested by a decent shop that specializes in automotive electrical work. You can do a voltage drop test to find out if the cables are at fault, but it's also a good idea to...

    “Pre alpha” leak

    You won't blow it up if you use higher pressure- look at the diagrams for the drive- it's not going to bypass a paper gasket and if it causes leaking through O-rings and oil seals, it may be time to replace those because they don't last forever. When the bearing carrier was out of the lower...

    “Pre alpha” leak

    The O-ring distorts and fits into the area as well as it can, but since the back edge isn't smooth, it may hold pressure for awhile, just not for long. Use denatured Alcohol to remove the sealant, especially if it was Perfect Seal or something like the Permatex mentioned before. Be careful...

    mercruiser shift cable install tool to help it tthru the bellow

    Yes, it does, but I remembered that the V-P kits came with Glycerine from working at the boat dealership and since I had some in my garage, I didn't need to search.

    mercruiser shift cable install tool to help it tthru the bellow

    I don't remember exactly (because it was several years ago), but I think I wrapped some tarp tape around the end to ease the edge, then put some Glycerine on it to lubricate. Glycerine is the lube hat comes with Volvo-Penta raw water pump kits and it won't damage metal or rubber. Woodworking...

    4.3 Mercruiser - randomly dies

    As I mentioned, my small Craftsman slip joint pliers make it easy and I can go in from many angles in cramped compartments. If I had a dollar for every boat I worked on for a no start problem with loose wing nuts......

    Did you make that?

    Shifting to Neutral for starting

    I lubed mine with Quicksilver 2-4-C but that was because I needed to disassemble for replacing the shift cable. Mine is an '84 4 Winns, so it was overdue for clean & lube.

    4.3 Mercruiser - randomly dies

    True, but the battery manufacturers could save money by omiotting the nuts. OTOH, that will give dealers something else to biatch about (as if they need something else). They often have the larger posts posts too, but the threaded studs are great for adding low current accessories if the boat...

    4.3 Mercruiser - randomly dies

    I think someone should tell the battery manufacturers- I still see new marine batteries with wing nuts. Wing nuts are OK for low current but I have seen a lot loosen form vibration, so I usually tighten them with a small slip joint pliers.
