hi there guys

I have a Stock Standard Pro Boat Shockwave 26 , ( components )
1.) BRUSHED 550 Motor
2.)Brushed ESC
3.) Stock servo
4.)stock reciever

i REEEAAAALY wanna go brsuhless and have come across some inexpensive yet good deals , however , my concerns are : will this motor fit the Stock motor mount ? , what Prop am i gonna need ? what turning fins ? and is this too much power on a 26' boat ?

thanks alot guys !!!
