big motor tight budget

[TravelingPencil]

What i need is a motor that has enough power and speed to drive a screw(the kind connected to a boat's engine) that will push a 250 pound boat through the water at at least 5 MPH for under $50. I also need a small screw, say 3" diameter to be driven by the motor for under $30.
many thanks to anyone that can find a motor that fits these needs.

junkyard.
 my sugestion is the blower motor from a car's heating and cooling system.
also see if you can find the screw to a boat there

So you wanna make your own boat motor?
Your pretty darn good if you can find one on that budget!

that might just work but my only problem is finding the motor in the car(how would i take it out of the car,where is it. i know it varies by make and model but a basic rundown would be helpful)

what about a weed whacker off of ebay?

they use it for bikes, why not boats?

behind/under the glove compartment. maybe more toward the driver under the dash

I am going to look into both ideas, but i'm leaning towards the weed wacker engine because it already has most of what i need(like a long output shaft to stick in the water). but then again a blower motor from a junkyard is very cheap so i might use both, one way or another

you could make a mini longtail boat with the weed wacker with very little modification.

I think I should have a blower motor left over from when i was trying to put one on a scooter. so if you want it, you can have it, if I find it.

COOL!!!

a mini longtail is a good idea but there is the question of where to get one, any sugetions

(I think Dunk was just suggesting that the design was proven and tested)
