I have a wooden boat and no strength to row after work so i decided to take up a challenge of building small outboard for cheap. I bought grass trimmer pole with axle for 22USD:

i got hold off 2 Audi 200 quatro turbo fan motors for 34USD. They are 12V, 500W, 2600RPM:

The axle with gears gives a reduction of 1:1.33, i had a 55T and 9T sprockets from cheap Chinese scooters which will give me a further reduction of 1:6.1 so total 7.4 so at 12V it should spin at 351RPM, just a little bit shy of 420rpm as per Jeremy Harris propeller on hes thread.
Left to do - propeller.
