Shifter is in forward and the

Shifter is in forward and the LU shift lever should be turned CW and pointing at the stern. While holding slight CCW pressure on the prop align the LU w/the UU shifter parts and mesh them together while aligning the LU w/the UU and bolt together per manual. To mesh the shift parts together slightly wiggle the prop. Don't add oil until you are sure it shifts properly.
