Best prop for application

[Juiced]

I have a 40hp 2 Stroke Yamaha on a 4.2m aluminum hull.
It does 55 klm/h @ 5,500rpm with a 11-3/8 x 12 prop on it now.

i would like to know what prop would be best for a lot faster speed.
i have rev limiter disconected so revs isnt an issue.

getting out of the hole isnt a real concern either. just want a lot quicker top speed.

can anyone help please
