Thread: 300 GT Johnson.. Whatever happened to the V-8's??

  1. #1
    It seems the more I try and find out anything about these motors the less anybody wants to talk about them. All I really want to know is if anybody knows where I can find some for sale or to rebuild. Any info at all would be greatly appreciated. Thanks.

    There all blown up by now! Buy two 300Xs and call it good. After all once you go black you you will never go back!!!

    look on ebay, they are on there all the time.

    Somebody told me that they weren't that bad of a motor if you ran the right RPM's... is there any truth to that or were they really that bad of a unit??

  5. #5
    actually they were good motors even to be run hard but the problem was the lower units, so much torque they liked to break drive shafts.

    They are big motors and don't usually like to turn big RPM. 6k tops. Very reliable if you ran them under 6k.

    Is there any marina's or salvage shops that anyone knows of that might carry the 300's??

    I have heard the V-8's run the same gearcases the OMC V-6's run. I know several guys with OMC V-6's that have blown up their gearcases. I couldn't imagine how many cases one would go through with a V-8.
    On another note, has anyone ever heard of someone mating a Merc gearcase up to a V-8? If I ever won the lottery, pig_flyi I would try to mate a highly modified V-8 up to a bravo style IMCO extreme gearcase. eek! That would be one bad a** combo on a 21' tunnel.
