I'm aware that the internals on the A are larger, but the 3A only had a 100 hp up in horsepower rating. I've destroyed several with my old 41 with 900 a side, so I'm not sure what's inside your friends but 1200 in a heavy boat is atypical. 1200 a side in a heavy boat will push a #6 past it's limits. Obviously if you are inside the drives regularly (and with 1200 hp regularly would be like 20-25 hrs) then your life expectancy does go up.

I checked with my friend again, he ran #5's on boxes on his heavy 38 non stepped cig for 5 years with absolutely no drive failure.
Now running same motors with #3A's with out boxes absolutly no problems last 3 years.
Granted, you can break anything if you try hard enuff.
For the amount you would spent on #6 with the rerigg , you can buy alot of # 3-5's .

Big job- basically a re-rig. The X dimension on TRS boats is almost always too deep for the prop advancements since they were discontinued- and the III is longer.
There's only one common-sense approach- the Konrad. It's power handling is 50 hp more than the III and 50 less than the IIIa, but you can use XR props on it. It's a tad shorter than the TRS so that cures the X issues. And it's a direct, no BS bolt-on.
