why? I am sure it was a bunch of work and looks great. but why convert to outboards when you can have a pair of diesels?

We had two Cummins. Outboards are so much easier, quieter and just work better where we boat. The boat runs better, lighter and is easier to drive. I think Intrepid says it best:

The advantages of an outboard: more spacious, more efficient, more range.
The 475 offers nearly twice as much topside and interior space as comparable sized inboards.

In addition to all the stowage, recreational and living space afforded by the outboard configuration, engine noise and vibration are dramatically reduced. There’s less smoke and fuel odor. The roar and shudder of inboard acceleration simply never happens. In all, outboards add the finishing touch of luxury, with fuel-efficiency and range increased by up to 50 percent.
The surefooted handling and precise response inspire total confidence. The hushed chorus of multiple outboards combines with aerodynamically neutral topside surfaces to reduce noise to “conversation level” even at speeds up to 55 mph. The hull form builds the trim in automatically. Bow rise is minimized, pitching and heeling are reduced, and the shallower draft means quiet seclusion in the shallower coves and anchorages an inboard vessel can’t reach.

Interesting & I like it.

What are the speed differences with the outboards?

Wait I thought you still had the diesels? Is this where you shed some pounds? What did it weigh before?
Any pics of the cockpit?

not in any way more efficient than a pair of diesels with surface drives that is a stupid statement.

What did you do to the space where the motors used to be?

Interesting to say the least. The fuel burn of the (4) gas burning O/Bs vs. the (2) Cummins diesels will tell the story.... No doubt access to maintain is easier. Wonder how it effected the boat's CG?
