Proper Prop...

[Captain Tom]

Will this prop add any performance to my UL-1...GrimRacer 42x55 2-Blade? The Ul-1 is all stock?

Best prop is l40/57/3, but you can try 42/55. I tried the x442, which is, in grim numbers, a 42/58. Worked ok, but needed more lift in my opinion. Hydros need lifting props, and the 42/55 doesn't have ALOT of lift. L40/57/3 has good lift and more pitch. Got 50 on stock setup with that prop

Thanx Dana...Was that L40/57/3 sharpened and balanced? There is no one local that can do that, that I know of...I live in New York State. I'm now using the 40/52/3
seems ok but if I can get better performance from the 40/57/3, that's even better. I will be racing my Ul-1 on the 8-9 of Sept. at Brick Pond, in Elmira, NY. 6 laps races.
Thanx again

He is in NY and does some of the best props around and can probably have it to you in a day or two.
I know local racer here who runs a 42x55 and has one of the fastest boats in our club.
Also a few of them run the 3 blade AQ prop with good success just depends on your preference.
IMO 3 blades are a bit more touchy then the 2 blades.

As Jeff said, contact dasboata. You will need that prop done very well. I've tried several props on that boat, and the three blade works best IMO. The l40/57/3 will take a couple of seconds to hook up, so when you nail it, it will cavitate a good amount, but then when it hooks up, hold on!

thanks Guys

We have tried the 40/57/3 prop...did not work at all on the UL-1 OR on a V hull Delta Force. Just to try that prop on a different hull. The 40/57 made the UL dive and the
Delta Force SLOW. SO, a 38/55/2 was used and it was a MUCH better prop, the UL flew.
