Err 33% more than it's rated for? If I'm reading your first post correctly, it sounds like the older version of the hull was rated for 40, but now 30? I would hazard a guess that with the older boats they found transoms and boats weren't staying together!
I had a chat with Humber about my new boat - turns out its the grandaddy of the Ocean Pro, but were I to drop an 80 on the transom (as per current O-Pro), I'd probably end up trawling the bottom looking for it! To put it in perspective, mine's rated for 60Hp.
Also remember if the 40 takes your transom off, your insurers will fall about laughing if you claim against it, as you've exceeded the max.
