35 donzi zx center console with 3 300 promax's possible
Everyone is it possible to place 3 300x promax outboards on back of a donzi 35 zx center console. I have seen one with 2 was wondering if the third one would be worth the mpg gain and what would the mph gain be

My 34' fountain with triple 275 Verados runs an honest 65 with fuel, people and gear on board.
Just for interest one day, I pulled the centre engine all the way up and ran on the other two. Needed lots of tab to plane, pretty sluggish but still got to 54 mph with a decent load. Considering it's setup for triples (props, engine spacing, engine height, the weight of the 3rd engine) I was pretty impressed.
Thinking later, if twins were setup properly, the speed gain with triples ain't worth it. Fuel, servicing, initial cost etc, etc. Trips for speed and if you're seriously offshore, you could still get home quickly on two but otherwise, I'd think carefully before spending a lot of cash.
My opinion on you're question, I looked at Donzis with triple Verados when buying my boat and see no reason why 3 promax engines wouldn't fit and you'd have a very fast albeit thirsty rig but for my use, I don't think it's worth it. Nope.
