A friend of mine was interested to know what speed gains and/or handling gains have been made by blueprinting the bottom of a 25' Thunder. He's planning on putting a 550 HP motor and was interested in what results others have seen and if it is worth the cost.

Thanks in advance!

Hey Kirk
I dont have an answer for you here but was curious to see if you ever got any feedback on this.
I have a 98 running about the HP you are talking about.

I'm interested in the outcome also. Have the same boat and am looking at 550HP next year!!
