Hi,

I recently replaced the water pump in my engine and in the process I had to remove the gearcase. When I try to put it back, the whole piece slides in and then stops about 1 inch before it is flush with the top half of the engine. All the screws are going through the holes, the water pump shaft goes in and as far as I can tell the shaft connecting the propeller to the engine is going in correctly also. Is there something I'm missing?

I recently replaced the stator to this engine also and had to remove the flywheel. Is it possible I need to spin the flywheel around until the shaft of the propeller aligns internally with the crankshaft?

Thanks,

Gordon

The splines of the drive shaft have to fit into the splines of the powerhead. Just rotate either a wee but and it should go together.
