If you mean those 600s with flux rings there are two in my trash box you are welcome to.  B- - - - - awful current hungry things.

In a word Stav, DONT.
Not unless you want your tug to leave your Perkassa standing.
They are fast motors but VERY power hungry.
If you use them at all run on 6 volts with a heavy ESC.
On 12 volts they kill ESC's easily as they draw horrendous current.
Why not try the recommended geared motors?
On 12 volts they run at aprox 19000 rpm, but as stated on here previously the stall current is OVER 100 amps EACH.

Stavros,
The geared 500 motors should power the yorkshireman with decent brass props.

Can always try the model motors direct they supply the 777 motor bearing at each end 7poles run really smooth and at 6v will turn a 50mm prop and only draw something  like 5amps amazing motors and the same size as a 540  O0
