New to theUL-1 and boating.

Looks as though I'll be going back to the basics to get this UL-1 back up to par on the water. After she's back, I'll be able to install and test my version of an airdam.0

That prop needs a sharp edge on the back side of it,
The front side you just want to clean up to meet the cutting edges of the back.
That prop like it is will heat up the setup fast.

Try a m445, you will be pleased

Just so you know, I used the stock three blade plastic prop on my UL-1 two years ago and was very happy with the result. At that time I didn't have a Grim 40x52/3 prop. I have never run the UL-1 with anything other than the plastic prop.
Fastforward to last month: I bought a used BBY Zephyr and for the maiden I used the same prop, later I used the metal prop, yes, it is faster, but in hind sight, for sport running, it really is not that much of a difference. So don't feel bad if you had a set back, I think you made the big step by doing your own prop, from now on you will gain experience that I wish I would have!
A bit of self promotion but I want you to see how this follow-up run with the Grim Racer prop compared to an earlier run in the video. (Search for the "BBY Zephyr Trial Run...")

Nice vid, I'll take another look at the prop later today .

So your saying it's not sharp enough?

Thanks, my point was that you can have fun and learn alot about setting up the boat using the plastic prop while you take your time figuring out what you need to do with your metal prop. While I can't say anything that I don't know much, Lenny is right, these props need to be sharp---which I think you realize, but actually they need to be THIN! Another words if you make the edges ( leading edge) sharp, your job is not completely done yet. You should post some pictures and I am sure you will get some good specific advice.
The metal props I buy is so sharp that they can cut your fingers if you are not careful!

Thanks for all the info, I'll keep the stock prop on until I get the GR prop correct
I'm doing some battery research to find something with more of a C rating. As of now, I only have 1 pair of batteries at the moment..

I got home about 5:30 and broke out the micro file set. Started filing the 40X57 prop to thin it out and make a very thin and smooth transition to the front side of the prop. I only have 2 more blades to go. After that I'll begin the balancing

Keep at it. I got lucky on my first time doing my own prop and achieved a positive result. I think with a little more work I can make it perfect in my eyes at least.

It's weird that I didn't think to weight the prop before I started .

I now know the importance of a properly tuned prop, here is a video of a poorly tuned prop.

Here is a video of a stock UL-1 prop, It's running aprox. 43mph. Once I get the boat tuned and setup correctly it should run a bit better.
It's all a work in progress.

Here is another video of my boat that I forgot I had. This is the very first run I was able to really open her up.
