Looking to supercharge my boat and try to run a 26p prop

[jokergerm]

so i am new to this whole prop thing. but i currnetly have a 21ft milan and i can run about 50mph with my high 5 19p i want to supercharge it and go to a 26p. i think i will have the power with my supercharged 5.7 to push the 26p to 4700 rpm that i am currnetly pushing

does any of this make sense?

do you think that i will be able to get to 65mph with a supercharger and the proper prop?

please dont make me sounds stupid about this im new

To attain 65 from 50, you have to effectively increase your HP by 255 from what you have now.

I think you would be better off to get a boat intended for more speed.
Your motor and drive train won't hold up well pushed to its limits artificially.A boat pushed beyond it design limits can be dangerous.As suggested it takes a lot of hp for a little speed.
