Anytime, Tom.
One other source of a clunk would be the dampener. This is a metal plate with a
splined hub in the center. The plate bolts to the flywheel and the transmission
input shaft slides into the hub. The dampener contains springs which absorb
torsional vibration. If the springs are damaged or if the bolts are loose, you may
get a clunk.

Yes, the transmission is bolted to a bell housing on the engine so that it
sits at the same angle as the engine. The prop shaft also assumes this angle
since it is direct coupled to the transmission. This is what is referred to
as a "straight inboard". On many newer boats of this size, the engine is
mounted backward with the front of the engine close to the transom. A V-drive
is then used to connect the engine to the prop shaft. On this type of
installation, the engine is not angled as in the straight application since
the prop shaft angle is accommodated by the angled "V" drive design.

Hah!! See, learn something new every day.

Thanks for the info Jim.
