PS...

You can take a round steel disk,,, cut your own slots,,, and bend the pitch you need using a heavy duty bench vice...

Start with very little pitch at first,,, then add 1 or 2 degrees of pitch untill you hear and feel the engine slow down,,, then back off the pitch 2 degrees...

Home made propellers work great with home made low hp engines ...
Try to keep it symmetrical the best you can,,, set up the bench vice and a stopping point for your pipe wrench so all 3,,, blades are angled too the same pitch

i paid 10 dollars for my prop if i remember off amazon... it was worth it, but i intend on 3d printing props in the future, i did do that before and it worked.... its just i graduated HS last year and dont have access to the skools 3d printer, but i will buy my own for 100 bucks soon...

Check with your local libraries, some of the larger ones have excellent 3D printers.

?! nope ours doesnt, but they are dirt cheap, around 100 dollars a pop from aliexpress.

3d printers are getting so affordable i can't believe everyone doesn't have one already. The parts are decently strong as well. Got wheel hexes i printed holding up nicely in my rc car and a blade disc for my mower that's holding up great as well just printed in pla.

I was thinking a vertical shaft push mower engine could be converted to a boat motor.

Yup, all you need is a leg and a coupling, and some mounting hardware.

couppling some people get away with hose clamps and some thick rubber tubing.... could work if your in a pinch

update: I tested it out in the ocean. First thing is i need to mount the propeller backwards, / upside down....
Its not rotating the right way so its pulling not pushing...
second. the waves were to powerful and big and overpowered it. i think lake / pond testing will be my second attempt.

Just strap it to the front like a front wheel drive
