    Jet Pump problem??? I need direction

    Can you all direct me to threads for direction, I have searched, like Beerdart suggested, and spent a couple of days reading threads. Here is the issue, 95 SLT 750 stock- I was wave jumping and when the drive would not work (towed in) and funny sound. I bought the repair manual and have taken the ride plate and rock grate off, was going to measure the impleller clearance and noticed the drive line has about 1 inch play back and forth(front to back). I think this may be the problem.

    Do I contue with removing the jet pump or look at the bearing housing?

    As you can tell I am the newb but trying to do this myself because I do not trust the local shop.

    Any guidence to the thread or response to would be appreciated. You all do a great job helping others out

    WELCOME to the Green Hulk Forums!!!

    So if the engine revs but the boat doesn't move or barely moves.
    Remove the pump and inspect the drive shaft impeller splines and engine coupler.
    Once out, you can check the pump bearings and stub shaft for wear.
    Oh, make sure nothing got wedged up into the intake grate area.

    Thanks

    Thanks PH , I will pull it out and inspect what you said below. I may have some questions and will hit you up later. I am limited on time and only get an hour here or there. Like I said the drive shaft moves about an inch front to back. This is not normal is it? Should it remain solid in place? I suspect that is the issue.

    They generally won't move that much but I'll bet the rubber bumpers at both ends of the driveshaft are missing.

    Welcome to the Hulk. Check to see if the engine mounts are OK and the pump mounting nuts are tight. The nuts that hold the pump to the hull. There are 4 on the inside and 4 on the outside. Don't remove them, just check for tightness. And DON"T overtorque them as it's easy to do and things will warp pretty easily.

    Thanks x, you and ph have given alot of people alot of help, and I appreciate it. Ph earlier said to start with removing the pump to check the drive line but you said not to remove the nuts on pump. That is where I am at in the manual, to remove the pump.

    Do I need to remove the jet pump to check the driveshaft rubber bumpers?

    It looks like I do in the manual for the driveshaft/pump installation.

    Yes you do. I said to not remove the NUTS attaching the wear ring (part of the pump) to the hull, not the BOLTS. The bolts near the back need to come off to get to the drive shaft. So you need to remove the steering cable, 2 hoses from one end, trim rod if equipped, and the 4 BOLTS at the pump exit, NOT the NUTS way in the front of the pump.

    How to remove a pump

    This is what the back of a hull looks like with the pump removed.

    These 4 long BOLTS are what you remove.

    Here's a picture of the bumpers on each end of the driveshaft,The one on the left is missing it,the one on the right has it.

    Make sure you don't lose them and that they are in place when replacing the shaft.

    Trying to remove the pump but it appears stuck on the upper right side. I have followed all the instructions in the manual.
    Am I just braking lose the silicone?
    I will just keep working it side to side to break it loose at this point. Have spent about 30 minutes.
