John, 
where can I get a setup like that?
+Think about it you running along and the bottom starts to get shallow the center engine flips up and your port and starboard keep running.
+You get to the dock early and want to take a slow ride use the center engine
+You get to the dock late use all three engines.
+ Center engine won't start use port, port don't start use starboard, what are the chances 3 won't start
+No oars, whistles, flairs needed what are the chances of 3 engines not working
-  I can't think of any
 
You think you can help my set up my barnaget with 4 engines?
