  • @austincoon1850
    @austincoon1850 Před 2 měsíci

    13mm trim tab anode bolt. 1/4” drive. Also, the alignment for the gear shift is important. You have to stick your hand in there as seen in video, but not mentioned.

    @pwcopy1 Před 2 měsíci

    This procedure also applies to several tow boats with direct- and v-drive inboards and engine-mounted pumps like my 1995 350 EFI Magnum Tournament Ski. I pull the the whole pump and use dish soap for the impeller.

    Terrible advice from this video. Was probably created by an AI bot. There are at least 5 other things more likely to cause a no spark condition other than the coil. Coils are almost NEVER the problem in this kind of motor.

    Great video!! I am not wanting to remove the wiring as my wires appear good but the guts are not. Bought new Merc parts.. The alignment mark part is not clear.. ..Is it the space between the teeth?? One of my new ones came where the actual tooth is on the mark. And the other one, the space between the teeth is lined up on the mark.. Plz advise..

    Do you have any idea if the prop shaft on one of these would fit inside the gear case of an old 200 black max? I’d really like to have the dual prop set up on my flats boat so it could hole shot better and run really shallow.
