I noticed on the lake yesterday the boat never got warmer then 130°F, could my whole problem stem from it running to cold, making the choke not fully open and not allowing it to create enough vacuum to open the secondary air valves?

No

I have a 1987 350 same carb.
Bone cold it will accelerate to 50mph with no issues

Lake test showed that everything from what the eye can see was functioning properly,

The choke fully opened
The secondary air valves opened under heavy load
The Primaries were opening as well.

It's got to be a clogged filter somewhere right?

what is the max ignition timing achieved and at what RPM?

Can't say exactly but I confirmed the timing was advancing far beyond the original at 2500 rpms, I did it on the trailer in neutral just to make sure it worked.
