I have a custom hull in a v shape thats about 18 inches. The motor and esc on this link http://www2.towerhobbies.com/cgi-bin...?&I=LXLVH2&P=0. And a 10-Cell 12V 1100mAh NiMH batterie. I also have a servo, a 2 channel radio, and a transmiter.

Missing parts a prop some layout for a rudder, a flex shaft, a coupler, a prop, and a brass tube.

Do you think the motor will be strong enough to have fun I mean I'm not expecting 20mph but I hope I'm not building a tugboat?
Also what pitch and size prop should I buy?
And last question is what angle should the prop be pointing pretending like the botom of the hull Is a flat plane and the prop is stiking out making a line with a measureable angle?

Thanks for all your help Ron!
