what size prop did you use iam building a 2 meter boat running a 2.5 horsepower 4 stroke, and wondered about a prop

[enigma3778]

Greetings. I used a 3.5" diameter 4" pitch silicon bronze propeller from the Prop Shop of England. This is on a chain drive system and I have been trying different gear ratios. You might need something smaller with an engine with less torque. Happy building.

how id you attach the shaft and propeller to the engine. great boat

[enigma3778]

I have a centrifugal clutch on the motor with a chain drive to a 5/8" jack shaft mounted on a pillow block bearing. That connects to a 3/8" propeller shaft by a rigid coupling.

hey great boat

what is it made of and how did you design it?

Cheers

[enigma3778]

Thanks. The hull is made of 1/8" plywood. The joints are held together by wires initially and then epoxy/fiberglass tape. After the epoxy cures, the wires are removed and a second layer of epoxy is applied. I didn't have any plans for this project. I just kind of "eyeball" it.

Is the boat scratch-built or did you buy pre-made??

amazing boat dude! 2 suggestions, batten down the hatch! and put a small amount of weight in the bow! the should be able to then achieve full speed without the worry of it capsizing or sinking! look forward to seeing more vidz of that boat.
