Water reversion was a cam issue on the 465HP. I never heard of it on the 450HP. If there was an issue it was either cam or vertical drop of the pipes from the elbow to the tip. Dry exhaust cures all of it. My dad, chuckbeecher would know how complicated it is to install dry.
I felt the cam on the 465 was a little radical. Just stand next or behind one and reminded me of being up close and personal with a Nascar motor.
Doller also felt it was the drop to the transom.
Again, dry solved everything except noise.
We had no laws regarding it in Texas.
But i do remember a digruntled group at Shades on Lake Travis and flying bowls or salsa!!
But we were told to leave Broward County when the boat had wet.
They are just Bad Azz sounding.
If noise laws will be a problem for you I'd try some "cans" on the back.
A another friend had triple 465's in a Scarab with dry and no problems.
The Gills were O.K. but I'd change to some type of tubes or Stainless Marine. Gills are so old school.
By the way ours had little pisser tubes out the transom for each side of the exhaust on each engine.

I just had not heard of these engines, & wanted to learn a bit about them. It seems, after reading thru all the input, they are a good, reliable engine, & as with any engine, ya gotta do the maintenance to keep em running .
A 32 with the the HP450's should run in the 75-76mph range.
