Hey guys, I recently lost throttle on my 30 hours 2015 spark. I do not see anything in stuck in the impeller and I was in deep water. The prop seems like its having a tough time spinning but the drive shaft spins freely. What can this be?

I just bought it from a previous owner and it has the SS wear ring and prop on it.

Is the drive shaft supposed to spin freely when I rotate it from under the ski? Maybe the previous owner did not tighten down the prop / impeller enough?

If the driveshaft is spinning freely, then the splines are stripped. The shaft has a splined end that goes into the crankshaft of the motor. You shouldn’t be able to spin it by hand. Known issue with these.
