My two cents - for going way long to the outside, the go-fast outboards got you beat because they can hang 50 to 100 miles out thar, which takes a loooonng time with a 18-knot inboard. It's tough to get a big ole diesel out more than 40 miles and back within 12 hours or so. Remember, most tourneys have a time limit on 'em.
For attracting fish the diesels can't be beat with the bigger hull noise, grumbling engines, larger shadow, more bubbles in the prop wash, nice second or third wave behind the boat, and wider trolling spread. This ain't true all the time but I'm just talking in general here, maybe even some superstition or something - hey just look at all those dinky panga boats catching marlin off Cabo, right?
