It's a normal thing for Merc's but make sure engine idle is at spec and you
put it in gear quickly.

Hi,
I've got a 20' bowrider with a 3.0l mercruiser inboard and an Alpha 1
outdrive. Whenever I shift from neutral to forward/reverse, I can hear and
feel a fairly loud clunk sound. Is this normal (it's my first boat) or
should the shifting be smooth? If not, any suggestions on what might cause
this to happen?
Thanks.
