1. Lift engine into boat and position so that enough propeller shaft protrudes through
transmission and output flange for propeller shaft coupler to be attached. Then install
coupler and position engine (no gap can be seen between coupling faces when butted
together). Adjust engine bed height if necessary to obtain proper alignment. Do NOT
use mount adjustments to adjust engine position at this time.
IMPORTANT: Engine bed must position engine so that a minimum of 6 mm (1/4 in.)
up and down adjustment still exists on all 4 mounts after performing final alignment.
This is necessary to allow for final engine alignment.

2. Ensure that all four mounts are still positioned properly, then fasten mounts to engine
bed with appropriate lag bolts or screws and hardware. Tighten lag bolts or screws
securely.
