    Unhappy More 2001 Virage Issues - HELP!

    So I went to put my 2001 Polaris Virage in the water today. I got it out, fired it up. I put it in gear and hit the throttle to take off. Here is where my problem started. It would not go anywhere. I pulled the seat off to ensure the drive shaft was spinning and it was. So I have no clue where to start. I just spent a few days rebuilding the motor and now this. Will it ever end?

    What do you mean by 'put in in gear'? The impeller is always engaged - there are no gears.

    Is there any unusual noise, like a grinding or metallic gear sound?

    Did you water test it at the launch ramp ON THE TRAILER before you launched it for a test ride?

    When you rebuilt the engine, did you inspect the drive line while you had the jet pump off? Splines on drive shaft, impeller and PTO engine coupler all looked good, not worn?

    Well what I meant was that in forward or reverse it didnt go but maybe 3-4 mph tops. And it was topping out at 5-6000 rpms with no go. It just sounded like it was hesitating. I checked the splines on the drive shaft and they were great. No issues at all with the drive shaft.

    If the engine is spinning at 6000RPM and you are not getting thrust, by definition the splines are slipping, or the rubber bonded coupler has failed.

    It is a direct drive system; engine turns = impeller turns.

    Often you can't tell just by looking at it how fast the drive shaft is turning, compared to the engine RPM. Out of the water on the trailer, with no water load, even a slipping drive line will spin the impeller. In the water under engine torque, that is where the slipping will happen.

    Remove the jet pump and drive shaft, and inspect all four splines, and the drive coupler on the engine for signs of slippage.

    So what kind of things should I look for when I remove them? Just the splines wore down? The drive shaft splines looked good when I had it off but didnt check the coupler

    Yes, you can often clearly see the splines worn or rounded over, when they should be fairly square shaped.

    You can clean the grease out with some solvent and a toothbrush, then have a look-see.

    Do NOT stick your finger inside the splines - metal splinters are not fun.

    Check the impeller splines, and drive coupler splines.

    I am gonna need a special tool to remove the impeller from the drive shaft correct? Do I need to remove the drive shaft coupler to inspect it properly or can I do it while still connected to motor? If I need to remove it do you have any tips to do it easily?

    Special Impeller Removal tool costs $10 from Overtons You only need this tool if you need to remove the impeller from the jet pump. The drive shaft just pulls straight out from the impeller.

    You can inspect the coupler on the engine with a mirror, but it is easier to do so with it off the engine.

    Use the 'rope trick' to hold the PTO piston while you apply a large wrench to the coupler. It unscrews in the normal direction.

    What is the "rope trick"? I will have to try that. I am getting ready to go out there and remove the housing and all to see whats going on. It's only 100 degrees outside. I may have to do it in small 15 min increments so I dont keel over.
