Has anyone successfully powered the Ariel with a 9.9 HP outboard?

Currently using a 8 HP 2 stroke Yamaha with remote. I feel she ALMOST gets to hull speed.

I realize that many OB well configurations have been customized over the years and will be different....my Ariel came with an Atomic 4, the prop shaft is still there and can still spin....but I suspect the A4 went a long time ago...possibly when she was named Mischief and came through the Eerie canal system.

Anyhow, any advice would help, as to what a captain has been able to fit.

Thank you!
