    Easy "stuck" pump removal

    I found an easy way to remove pumps that are stuck due to salt corrosion or sealant. First you need a "Come-along" and two tie down straps with hooks at each end. I used two trucks with my ski still in the trailer so it wouldn't move.

    After unbolting and unhooking all hoses and cables:

    1. attach trailer with ski to truck
    2. attach one tiedown strap hooks diagonally thru the bolt holes, and do the same for the other two bolt holes.
    3. attach one end of the Come-along to both straps
    4. attach other end of Come-along to the other truck or immovable object (tree, ect...)
    5. start cranking the Come-along.

    The pump will just pop off. One suggestion is to have someone else hold the pump will you crank the Come-along because the pump Will hit the ground.

    I have included some pics to help you out. (sorry about the quality, I used my camera phone)

    Looks good but just a suggestion...

    Get some pressure on the pump with the comealong, and tap the side of it with a hammer. If its REALLY stuck, you sure wouldnt want to rip the entire transom out of the boat !!!

    I agree. On mine, after two cranks on the Come-along I could see the pump starting to split. But be careful nonetheless.

    wOw, this is just my opinion, but I would in any way risk doing it by that method. Especially if it were to pop out from breaking loose flying at you.

    I've seen a few stuck pumps, and with a rubber mallet, some heat from a propane torch and a tap of the chisel has always worked for me.

    I just don't like the idea of putting that kind of stress on the transom.

    And I don't like the risk factor that involves. It may work, but, I'm just stating my opinion.

    If your pump has been in there that long you might as well leave it .

    That is not a bad way to remove the pump. There is a very easy way to make it safe. Simply screw the two bolts in the two holes that are not being used. Dont screw them in all the way, just a few threads. That way when the pump breaks loose it will not fly off or fall off. The bolts will hold it on.

    Stuck Pump Removal

    Here is what I just did yesterday to remove the pump on my wife's 2002. Never been off.

    * Pump has never been out. I beat on it for about 1-2 minutes with a rubber mallet. No-Go....

    So, I did this, I applied a bit of "tension" to the stator and liner housing. How did I do this ?, I learned this from some machinists years ago at the refinery I work at. They use this technique when separating blind flanges and valves. But they use Brass Wedges with 5lb mallets.

    Here's what I did:

    * I removed the bolts, tapped a chisel pretty firm/hard in between the "little-ears" between the liner and the stator housing and let it sit for about 10 minutes.
    * Those litle ears are on each side of the pump stator housing and wear ring.
    * I did not tap too hard as to break the ears or bend them, but enough where they are "wedged" in there pretty good.
    * I left for about 10 minutes.
    * When I came back, the pump had separated itself away from the liner by 1-2mm. I then used a rubber mallet and tapped it a little to get it slide out and voila' ! it slid right out.

    The "tension" from the chisel (wedge) helped to break the sealant that was used and help pry the two peices apart.

    hey rx951

    that the same method i used to pull "old school" flywheel off two strokes..
    those thing would freeze on there so bad you would bend or break the flywheel puller bolts right off.

    started just putting tention on them, squirting wd40 on the crank shaft and then going to bed. next morning "surprise" its all laying in the hull.

    time and tention will work better then brute force everytime.
