Hi All,

I have a 23CC engine lying around and had an idea with winter coming up. Similar to a Zen engine but it's a Smartech brand and there's a few different mounts. Instead of a hovercraft I though about making a snow boat. Kinda like those Florida swamp boats but I'd use it for snow only. There's a few tihngs I wanted to ask.

1. I wanted to use a prop. Should I use a 2 or a 4 blade?
2. What prop size should I look at?
3. Will this set up be enought to push something 10- 15lbs on the snow?

Thanks,

Joe

Hello Joe,

Well, I don't know too much about what your engine will push along the snow, but I do know that I built a similar project last winter.

Mine came out at just over 4 lbs, with a ringed .40 up front. With this setup, it goes as fast as you want at half-throttle, but you need to give it a shot of full throttle to get it moving (especially if it has sunk into the snow a bit).

As always with props, 2-blade gives more thrust, but 3-blade helps with clearance.

Here are a couple of pics of mine, it has been sitting since the snow melted:

+ YouTube Video

I posted a build thread here if you're interested.

Hi Ben,

Thanks for the info. My engine alone is about 5lbs and from what I've see with the US builds the hull will be 20" x 36" or longer. The main things to look out for first is the adpater and prop. The rest will be fabricated with aluminum pcs.

It moves without even using the throttle!!

That looks awesome! Can't wait to see it go full throttle!
