    Tow rope wrapped around drive shaft

    Hi guys,

    New member here. My friends and I were on the lake enjoying some tubing with my ‘19 GP1800R this past weekend, but our fun was short lived due to the tow rope getting sucked into the intake and getting wrapped around the drive shaft killing the power to the engine. We towed the ski to the dock and loaded it on the trailer and took it home with the rope still in place. After a couple hours under the ski, I was able to get the rope off, but boy was it tight on there! It was all wrapped around the end of the shaft going into the engine bay, but I was able to cut it off without removing the intake grate.

    Could the rope have done any damage? Is there any sort of o-ring in place as the shaft enters the engine bay that I need to worry about having been damaged? I just need to know whether anything needs to be replaced and if I should take the ski to the dealer. I posted a picture below of what it looks like after the rope came off.

    Luckily the yamahas don't have any kind of oring or seal that goes around the driveshaft, just the coupler hose. If its intact you should be fine. I've done the same thing before. Had to pull the whole pump to get the rope out.

    Trick: Remove the spark plugs, then turn the driveshaft/impeller backwards to unwind the rope. I've removed ropes undamaged before.

    Thanks. Can you please clarify what you mean by coupler hose?

    Good to know moving forward! Hopefully won't need to go through it again.

    When pulling tubes or other things, I make sure either the rider or the person sitting behind me is responsible for pulling the rope in when we stop. It sucks when you loose time on the water because you've got to remove a rope.

    The short black hose about 8 inch long, 1.5 inches diameter, when looking in the rear of the ski under the seat. The impeller shaft goes through there.

    You're good to go other than that little scuff in the paint.
