I wonder if your problem is similar to a problem I had where the lower unit
was intermittently not shifting ( my post on overheating at low rpm's).
When the water pump in the outdrive was replaced, there was a spacer that
somehow disappeared when the split drive was re-assembled (not permitting
the shift shaft to fully engage).

Can you turn the upper outdrive driveshaft and make the prop turn (versus
turning the prop shaft to make the upper driveshaft turn)? The gearing does
make it difficult to turn the shaft by turning the prop. Also make sure the
shift lever ou the outdrive is pointing forward (so the unit is in forward
gear).

Hi Guru's,
I took off the foot to install the new waterpump. I had difficulty
getting it back on and noticed that the prop won't turn the drive shaft no
matter what position I have the shift shaft in. When I was removing the
prop, it moved backwards and clicked a time ot two when I was getting it
into position to wedge the block. Any idea's on what the problem might be?

Thanks, Mark
