Question

How fast will a 9.8 mercury push a 14' flatbottom boat?

Answer 1

I had one ona 10 foot tinnie and I'd say the first 2 answerers got it about right. If you know what pitch your prop is and you have acess to a tacho , you can go here and calculate your speed for yourself                                                                      http://www.rbbi.com/folders/prop/propcal...

your gear ratio's 1.7:1

10% prop slip should give you a fairly accurate speed.,

Answer 2

15 mph

Answer 3

probably around 15 mph with one person .  the more weight, the slower it goes.
