Default Bravo 1X Shifting Clunk Normal?

Replaced my failed Bravo 1 upper with a reman Bravo1X. When I shift into forward or reverse, the shift is quite firm, with a audible clunk. With the old upper, the shift was smooth with a slight delay before the prop starting spinning fast enough to start propelling the boat.
I'm running an Imco -2" shorty with a 1 1/4" prop shaft and a Merc solid hub kit.
Is what I'm feeling/hearing normal?

I've had a few Bravo drives over the years and some bang into gear and some shift smooth as silk. My current drive bangs like a cheap ho. Has from day one regardless of shift cable adjustments. Still bangs 400+ hours later even after a full rebuild including new cone clutch. You can't adjust it out of it. It is what it is.

My Bravo's always had that clunk.
When I got boat with trs's, I couldn't believe how smooth it was going in & out of gear compared to Bravo's.

Two different animals.
TRS drives are controlled by a transmission, hydraulic and smooth as silk.
A Bravo is a version of a crash box, the cone clutch design takes the edge off the shift, it can only do so much. The newer swept back design does shift better due to some changes.
