DF33 speed

[blakybob]

For those of you that are running the DF33 with a Neu 1515 1Y on 4s2p I have a couple of questions. What kind of speed are getting? With what prop? How many amps are you pulling?

I was figuring mid fifties and about 180 amps with a x642. Low fifties/high forties and 125 amps with a x442. Is that in the ballpark?

I can tell you that the 1515 1Y in my Sport hydro is slow with a 442 prop. It comes to life with a 445 though. It seems the 1515 really likes the larger diameter props. Even with the 445 prop my hull isn't pulling over 125 amps.

Even with the 445 prop my hull isn't pulling over 125 amps.

Is that a x445 or a m445?

I would also be interested to know what props people are using and what speeds they are getting. I just ordered a neu 1515 1y to replace the 9xl in my DF33. I have a few props to try, x440 x442 x637 m445 x640

I run a M445 prop but to be fair its a different hull type.

I'm running that set up on 4S1P, and a detongued X442. I would estimate high 40s, and less than 125 amps (running an uncooled Barra 125 and it is only warm after a race).

I tried a detongued X642 and it didn't seem any faster, so I went back to the 442. But I didn't spend much time tuning it with the 642.

Going to try an M445 this weekend if the water is good.

Both Doug Smock and I run DF33's, 4S2P, 1515 1Y turning DT x640. Speed low 50's, amp draw less than 100.

Thanks for the help. Doug and Casey know I need all I can get.
