If the boom itself is a single tube then consider adding a tensioner on top about 3" to 4" above the actual tube. It could be welded on of plate standoffs and a rod atop the standoffs.
Or it could be a cable with a turnbuckle for tensioning although you will still need the standoffs.
THe tensioner should be brought all the way down to just above the deck pass through.
I am not suggesting this will get you double the capacity but should add another 100 #. A good fabricator should be able to help.
As for the engine if you figure the 9HP Tohatsu is workable then get the 15hp for the same weight.
I did not have quite this problem but when I was buying our O/B for our dingbat I let my wife talk me into the 6HP Yamaha engine. It would not quite plane the boat with the two of us. I rued the decision untill it was stolen 2 yrs later, no I didn't do it, and then replaced it with the 8hp Yamaha at the same weight. World of difference.
