If you can afford the 115, put it on there. DO NOT GO WITH LESS THAN 90! You will be terribly disappointed. Just got rid of a 1650 Alumacraft tunnel hull and like Pat mentioned, hydraulic jack plate, cupped prop and a compression plate will allow you to get every bit of performance out of it.
I love tunnel hulls, as they'll go places a conventional hull won't, but there are trade offs. If you're looking for a speedy boat, stay away from the tunnel. They are designed to go skinny, not fast. That's why you want to go with the biggest motor you can get. Anything less than 90 and that boat'll just be a dog.
