I know that Kryptonite built at least one 27' with outboards. It ran about 15mph faster with twin 300's than a 600hp IO version would run. So not too normal, but apparently it works for some hulls.
I wouldnt mind having a nice OB powered boat, no standing on your head in the bilge, instead you are standing in your driveway. Plus, you blow one up, you can get a new powerhead slapped on and be back on the water in a week or less. For a whole lot less money at that.

Hey good advice on this stuff!! My plan would be to install the outboards with a bracket not directly to the transom. I did have a 32 active thunder Face Off sold it two years ago then was told bank took it then went to auction don't know who has it now if anyone knows let me know!! The active thunder was a perfect boat I'm just sick and tired of working on IO's and the fuel it cost to run these boats I know you have to pay to play I understand that but outboards just seem the way to go!! I look at it this way if I blow an outboard I can purchase another about anywhere take it off myself and be on the water the next day!! Also speed is not a big issue with me not anymore anyways. So if I buy a hull that has the motors out of it what would be the steps to putting on outboards with brakets?? Thanks you guys its good to be back on offshoreonly again also any pics would be nice!!

He's got some very good ideas, will be much stronger then simply closing up the transom, adding knees and bolting on a bracket...
More work but much stronger

You would probably have to add some knees to brace up the transom. Not difficult for an experienced glassman. And we can change out a powerhead and be back on the water in less than an hour. Personally I won't ever own an I/O boat or cat.

Some boats will porpoise pretty bad when converted to outboards
since they were not designed to have center of gravity that far back.
Just depends on the actual hull it will be done to..

I just finished converting my older 30' v bottom with Merc 300XS. I absolutely love my boat again. I did it for all the reasons mentioned. There are many more. Call me (315)382~8828. Too many things to say here, I hate typing. I have pics that I can email. Thanks

I know everyone says "outboards use less gas" but that's just not always true. If it's a larger heavy boat you need torque to get up and to stay up. That's where the old adage " there's no replacement for displacement" really rings true. So if you put two large outboards on say a 34' Venture you have to stress those power plants to get what you need- if you had two stock 6.2's in the same boat it would ride better( more weight "in" the stern of the boat to mash the waves) and as the motors produce more torque it's going to be a more fuel efficient boat. My buddy's got a 26 Pursuit with a single 250 Yamaha 4 stroke and get's 1.85mpg at cruise. I have a 28' Pantera with twin 6.2's and get 2mpg at cruise... and I'm cruising at 40mph - about 10 mph faster than the Pursuit. Now maybe with blown performance inboards all that changes, but in my opinion on heavy boats, and dealing with stock power, the inboard rules on the efficiency front. I've never seen any actual MPG comparison numbers to disprove that.
