    Converting Mercruiser MC-1 to Alpha

    Sounds like a lot of work/figuring to make it work. But I guess parts are just not available to rebuild those old drives. A complete change to the 4.3/Alpha Gen 2 would seem to be the best in terms of finding parts and keeping it going. It is a shame to give up on the old inline 6 but to keep...

    Drain Plugs for 1999 Mercruiser 4.3 Thunderbolt 6 cyl

    Maybe it’s the square plug on the front of the intake manifold. It’s hard to see but would be behind the serp belt near those disconnected hoses on the left side of that pic.

    My boat sank, part II

    If anyone has a roller trailer and a truck or Jeep with a front hitch on it that would be one possible way to get it off. They launch boats from the beach that way in Australia

    My boat sank, part II

    This is why I like my salt water mooring, yes you have to deal with bottom paint and painting the drive/transom mount but compared to docks & lifts I feel that as long as your ground tackle is adequate it is the safest in any kind of storm situation unless you pull the boat. I have a 250 lb...

    Cobra Outdrive Sucked Up Some Sand

    Also search on my user name for the steps to properly set up the OMC Cobra shift linkage. Once it is done right, with a good shift cable, with the ESA working, and all adjusted right they shift VERY easily. Mine goes into gear with a nice solid "THUNK" and goes into neutral with 2 finger...

    Cobra Outdrive Sucked Up Some Sand

    Ok if you have the complete outdrive off, then put muffs on it and flush it with the imeller housing removed so you can see if water comes out of the water port behind it. You will have to change the impeller anyway because it got worn from the sand you sucked up, the wear plate will for sure be...

    Never underestimate the power of the mechanical fuel pump

    Ok this is interesting because I tried to use a brand new Holley on my old engine after I rebuilt the top end. Had a lot of trouble with rich running that I could never solve. I actually pulled out the old Quadrajet and rebuilt it and it ran much better, then decided to replace the original fuel...

    Cobra Outdrive Sucked Up Some Sand

    If its that badly packed, you also need to remove the impeller housing and flush it both from the water intakes up ward and from the raw water intake hose backward. With the impeller housing off you can see if water is able to flow from the water intakes to the impeller and from the impeller to...

    Mercruiser 4.3 woes - help please

    Don’t forget to check the anti siphon valve on the gas tank. It’s a spring loaded ball valve that is supposed to shut off the fuel flow if the fuel line from the tank to the filter leaks. I had this same problem on my boat years back when we first got it. The engine would start and rev fine in...

    New Volvo 250 HP PY20

    The reason given in the article is to save fuel. The amount 'saved' is likely not even measurable, especially on a marine engine. Boaters do better with simple inexpensive to repair engines. Sounds like the electronic thermsotat used on some Benz and BMW engines. A perfect way to take a simple...

    Never underestimate the power of the mechanical fuel pump

    That is very odd. I had the OE pump on mine for about 30 years and then replaced it with a Sierra. Both worked fine, never had a flooding problem. One thing with the Q-Jet is that there is a hanger for the needle valve, and the bracket for the float has a couple of small holes, that hanger just...

    more un-asked for complexity, that in the end, doesn't benefit much.

    I’d check for spark when this happens next time. You just want to cover all the bases

    new carb new issue

    If that’s fuel in the water it would seem that three possibilities exit: Electric choke not staying open Carb floats sticking or needle valve not holding Fuel pump pressure too high That’s way more than what you’d see from the idle mixture being too rich.

    Electronic Ignition and Shift Assist

    They sell an ESA that works with both points and the conversion electronic kits like Petronix. I replaced my old ESA when it stopped working about 6 years back with that one. Call them & ask but I’m my case I just continued using points.
