We have triples on a 48'er Sunseeker with 502MAG's and bravo drives. Never had a drive failure but tons of engine issues.....and I dont' think it's the boat's fault even though it is over 19,000lbs. I've had a engine issue and had to run on two and can still get up on plane. 
It's been proven a few times!
Since June we have been rebuilding all three drives, all three motors, bottom paint and next is a dash/electronics redo before spring. Somebody will get a nice boat next year!
I would image that that the center of gravity (COG) would be affected quite a bit if you removed an engine.

What is your opinion of taking a triple engine boat and removing the center engine and driveline and reglassing the hole in the transom.
If the tripples gave a top end of 75, would the twin version (with new props) reach 60? Leaving the remaining two engines exactly where they are in the back of the boat.
I fully understand that to do this properly, you would want to remove all three, reglass the transom, and then install higher HP twins on close stagger. But, if you could get a tripple at the right price, you would also result in a spare engine and drive as part of the deal.

I am sure it would be affected, just may not be negativly. Didnt they made the 45 Sonic as well as 50 Outerlimits in primarily triples till they opted in favor of twins? I think it would also depend if it is a large displacment performance boat (like yours) or say a 47 Fountain lightning
