Prop Alternatives to ABC?

[dmitry100]

Hey guys,

Since it seems its pretty much impossible to get any specific ABC left/right prop pair from their prop spec sheet... Are there any other good prop alternatives to ABC in terms of rake, BAR, etc ?

Looking for something in the area of around 17-RAKE ANGLE and 45-BLADE AREA RATIO...

Does Prop Shop have similar props like this?

[dasboata]

none <<<<<<<<<<<<<<<<ABC new line is very unique I can custom cut octura or PS but the ABC 17* are the way to go !!

[kfxguy]

What props are you looking for?

[dmitry100]

dasboata: mannnn.... custom cutting an octura or ps can come some-what close to that kind of a rake/bar ratio?

ABC still being dodgy lately? I'm gonna assume they're just completing orders for the most popular of the props or something for places like OSE, etc....

I can do 17* but you will loose pitch,blade area and cup so it must be compensated with a larger prop

Ah, so i'd have to get use a bigger prop in general?

Anyway, maybe ABC's are not be the best option for dihedral twin drive hulls... as it may create too much lift especially when theres a lot of pitch.

Dasboata: Anything special about props from Propshop in comparison to Octura? besides being stainless steel, etc.

If your your boat is dialed in well with an octura prop and then you switch to an abc and do not take the time in getting it dialed in again for the abc...it's simply going to be undriveable and keep flipping. The selection of abc props is so much more vast than octuras there's no reason you can't find a suitable setup. You might simply be trying the wrong things.

kfxguy, I'm just mentioning things others have mentioned about the ABC's with the hull combination (keith and others). Maybe I'm mistaken, but I was just giving myself a reason not to wait up longer for ABC lol... maybe once they start fulfilling prop orders later on... whenever that is.
The props have to be cut down cuz there was no particular one without being cut but anything that is a left/right pair that can be cut down to 42mm and with pitch of 1.8 for a total pitch of almost ~3 (2.97).

[dmitry100]

dasboata: What is ABC's excuse these days? Oh well, maybe we could just order the 17-17-45 CLL & CLR from OSE... they're in stock and total pitch comes out to be 2.89 -- I can live with that for now.
(Unless theres anything else that can be done to it to increase the pitch slightly).

Should I just go ahead and order them to you then?

[dasboata]

I have a set of 1814/17* or 1815 in stock if that's any help ?? That's fine have Steve send them to me !!!

Just trying to help here but not act like I know everything. With that being said I'd like to point out a few things. First thing is if your running a Lehner motor(s) then they (in my experience) might not like all that pitch. Second, abc props (what I've been told by James Schaefer the owner of abc) is that those props have extra pitch casted into them. In other words if you try to compare a 1.8 pitch octura vs 1.8 pitch abc, the abc will load things more, and usually be faster. Case in point. I've done back to back testing of a m645 vs a 1815. The 645 is a 1.6 pitch and the 1815 is a 1.5 pitch. Both right at 45mm. The 1815 would soundly beat the 645 by at least 10 if not 12mph. At one point I actually went faster on 5s with the 1815 than I did with the 645 on 6s.


You can take my advice or not, but if I were you I'd start out with a set of 1714-17-45 or a set of 1715-17-45 and dial the boat in on those. I don't see you being disappointed once you figure out what the boat wants with those. I'm so confident in what I'm telling you that I'll loan you a pair of 1715's and if you like them just get a set from Dasboata. Btw, the 1814's that Dasboata has are EXCELLENT props, that's how I got my stock zelos to 76mph. Those would work great too but for some reason you seem to want around 42mm.

kfxguy, were you keeping track of how much amps that thing was pulling between the 645's and the 1815's ? It's good advice and I think I've read you mentioning it before as well.
I have a pair of 1715's and 1815's and they'll be all good for initial testing. Just trying to get more stuff to test afterwards as I know the those will only take me so far.
My 2 hulls are almost done, probably a few days to a week left of work, so I'll have some videos of them posted soon... they took way too long to build... lots of procrastinating and overthinking, etc (Mostly just wanted to get it all done the right way first... to avoid major mods later).


dasboata: Those 1817's are they 17* and .45 bar?

sorry typo 1815/17*

[dmitry100]

dasboata: Check your email. Your usual address from your biz card is fine to ship those props from OSE?

Btw, is there any particular way that you bolt-on ABC props onto prop shafts? The 3/16 and ESPECIALLY the 1/4 sized ABC's have a lot of play when sitting on the shaft (before being tightened). I wonder if there's a better way of going about it...

I'm actually using some 3/16 to 1/4 spacers from Octura for those 1/4 ABC's you cut for me. Do you have any better spacers by any chance? (Or able to make something better for them?)
