How fast would my boat go?

Question

how fast will a 20hp 4-stroke tohatsu outboard with the stock prop push a 14' x36'' flat bottom aluminum boat?

Answer 1

i dont no how much it ways but my jetski is fairly heavy and has a 75 HP motor and does about 35.  So if its aluminum its probably pretty light so i would say maybe like 20 MPH  

Answer 2

Isn't that boat rated for 7.5hp max?

Answer 3

go to you're nearest sporting good store and get a GPS and use that.

Answer 4

Hay, listen to the experts like, Jtexas, get a bigger boat!  It's not safe to overpower john boats.
