    1980 Mercury 200 Front half change to an 86 front half 2.4 L

    I have an 80 200 Mercury #5464805
    I have an 200 Mercury 86 front half with carbs (complete)

    Can I put the front half on this engine?
    and will it work correctly with out problems?

    I need to have the electric enrichiner on this engine instead of a choke set up for my application

    The front will bolt on I believe,I haven't done it,look at the crankcase mateing surfaces at the oil pump area to see if they will seal.The block from the 80 will have the inside bolt pattern on the heads,and no fingerports,The 81 225 was basically that block with a 7petal front,rated at the flywheel.The motor should run well,but won't make the power of a later finger ported motor,you'll need to work with the carb jets,Chris

    I alwayz leeve out tha dowl pins on tha block halfs and let tha crank line tha front half...I have had a couple that didn't turn free, and don't recomeend use'in it if tha crank don't turn free after torque'in tha front half on......Also have run into the end seel cap(bottom) lock'in up tha crank after use'in mismatched fronts....

    other than sum oddity type stuff, tha front should juss be a swap!!...Performance differnce won't be enuff to tell(if any at all)...JMO

    I just had that problem, where the the bottom cap was binding up the crank. If I loosened the bolts just a tad the crank would rotate ok. Is it ok run like that?

    I am planning on using the carbs that came off of the 86 block (the 86 block has a hole in it from a piston) hence the swap questionwill I need to re jet seeing that I am using the 86 carbs?

    The block I sent you is the newer style with a good horizontal front half. Is there some reason you don't want to bolt your carbs on that one? What carbs do you have 86' intake?

    I've run inta that a couple times. I removed tha snap ring at tha big bottom bearing and gave it a light smack (bearing) with a tool used to install a new bearing, used a NEW snap ring and tha bind went away (and stayed away after runnin' a while). Sometimes it only takes splittin' a fine red 'unt hair ta bring things back ta where its supposed ta be..............Maybe I've just been lucky, donno....

    And NO, don't run it that way...............
