I ordered a new propeller for my 2000 johnson 150 V6. The new prop is a Michigan Wheel Vortex XHS #992003 with the universal hub kit. My old prop is also a Michigan Wheel but is not the vortex and the hub is already installed with the prop. The problem is that the new thrust washer that came with the kit does not fit onto my my shaft on the motor. So I'm wondering has anyone else had this problem? Would it be wise to use the old thrust washer that came with the old prop?
