We have a GT 187 150HP Third time the impeller seems to slip off drive shaft and is separate from engine.
Engine runs fine. Impeller is free wheeling with no propulsion. Boat is at the dealer.
Anyone have this happen? Third time for a repair?
Thanks for any ideas.
Terry

I had the opposite happen, The shaft and PTO wear at the PTO side due to lack of grease and/or poor alignment. Any chance the engine has some bad mounts causing it to move? The pump and engine are bolted on such that the shaft size is exact to keep this from happening, so something is funky. The system is not very complex, but with the boat at the dealer they should be able to say what is going on. Their explanation needs to at least make sense and follow logic.

Best of Luck!

The dealer checked motor mounts and alignment. Replaced drive shaft, wear ring, and miscellaneous parts under warranty.
im back in the water for a new season, with fingers and toes crossed. All good so far.
