    Arrow How to make your own PW-47166 MSX driveshaft coupler removal tool

    Thanks to Keddano for providing the outline tracing.

    You will need the ability to machine metal if you want to replicate this SPX tool.

    To use the tool you remove the rubber spider from the center of the coupling. This of course requires the jet pump to be removed and the drive shaft slides back as far as it will go.


    Make sure the removal tool is fully seated into the coupler and fully engaging the coupler 'legs'.

    The poor-man's substitute is a chain type Vice-Grip wrench wrapped around the coupler.

    I have even used a hardwood broom handle, but the stress on the coupler ears was worrisome.

    Here is the outline of the tool. The original was made from thicker than 1/2" steel, as I recall.

    The square hole in the middle is for a 1/2" drive ratchet or breaker bar with a long handle.

    These couplers are really torqued tight by the engine in operation. Getting it loose requires several grunts. Don't hurt yourself or the watercraft

    The attached PDF file is to be printed at 100% and used as a template. Use the measurements in the next post to confirm the size is correct.

    Note that the measurements were set to exactly line up with the pen outline. The camera lens makes it look like the calipers are set slightly wide, but this was not the case.

    Make the square hole either to fit a 1/2" or even a 3/4" drive tool, if you have one

    I can attest a pipe across the coupler ears... is not the best option.

    The thanks goes to Richie, He loaned me the tool. Which I have to get back real soon. Doing the square could be tough as they are normally broached, but you could drill the 4 corners. machine the center out. Maybe better would be to use a extension and cut the male part off and drill a hole in the center of tool and weld the extension to it.

    Why not just buy one that's already done?
    Its expensive, but it fits perfectly and wont damage the fingers of your coupler. I have a few, but Zig at Watcon has taken over production.
    The price is $85.00, but I don't think you can make one for less unless you have a machine shop & broaching tool. https://www.watcon.com/tools/drive-c...drive-couplers

    Have a great Thanksgiving!

    POLARIS driveshaft coupler is normal right hand thread.

    But often VERY tight, so can take a huge torque to break it free.

    You have a Yamaha, correct?
