As far as economy goes, I had a Formula 20 SC with a 330 horse 350 engine. We could run from the boat launch to Passage Key and back on about ten gallons. The same trip in my fishboat burns about 50% more, not to mention oil.
The newer OB's are pretty efficient. Our 25' Whitewater with 200 HPDI Yammies see's 2.3 MPG @ 40 MPH constantly, and has seen 2.5/6 when you really play with the trim etc. Nice thing is when one goes, four bolts, a few cables, and ya just kick it to the curb...
Some like chevy some like ford, some like CC and some like long deck, some like relaible power that was designed for boats and some like inboards that was designed for trucks, some like the mother some like the daughter......
Be happy with what you have or trade it in to something you are happy with, inboard or outboard - your choice...
2 merc 700/ nxt packages. 160 grand + or -.1400 h.p .3000 lbs. 100 hr rebuilds, 3000 for props if your lucky. aint hackin plowing some fat fisher around for 100 hrs.
5 verado 300's, 75-80 grand, 1500 h.p, 3000 lbs, 2500 for props, and will last 1000 hrs and push the fat fisher with some good speed as well.
Every since i went to outboards I have not gone back to I/O's...when I think about it and go climb in a I/O boat I remember how much I hate being in the bildge and working out outdrives and how I love being on the water.
Outboards work well for me.
Long term on the new motors, guess time will tell.

Hey HighLife - nice to see someone from Hingam on here - I lived in crow point for a while - great area.
Good thread and comments from everyone - this was not meant to be a "what is better - outboards or I/Os" discussion. Once upon a time outboards were cheap, simple, bolt on power - times have changed. They are now high tech, far from simple, and big dollars.
For those who want a larger boat - something that can be a performance cruiser (cruise at 30-plus), sleep 5, have A/C and room for all, the choice used to be diesel only. Then with higher output gas inboards you could get away with BBCs for a vessel up to 15,000-20,000 pounds, save some weight and initial motor cost.
I guess I was wonderring if a boat of this size could be moved efficiently with 3-4 300 hp outboards. My next thought was does it make sense cost-wise vs two Big Block Chevies.
My neighbors 2005 31 Fountain with twin 225 Opti's get 2.2mog at cruise and will hit 64mph WOT.
I get 1.5-1.3mpg depending on water and load condition cruising at 50mph 4100rpm with trip 275 Verado's. this is on a 38 foot 10'6" beam 13,000lbs boat with a full top, radar, big windshield and antenna's!
The Verado's get pretty good mpg as long as you keep them 4500rpm or below. Also the Fountain 38TE hull is super efficient too.
With the gas prices today the engines and hull need to be as efficient as can be. In the coming years the boat manufacture that can product good riding efficient hulls will win sales.
