Acme 1236 v. 1464

[OKWAKEBDR]

I am considering purchasing a new prop for my 2005 210TE. I live in Denver, so I am using the boat at 5-6k + ft of altitude constantly. I have been running the Acme 856, and it does really well. I also have a 644 which does okay, but doesn't get the boat up as fast I would like, and it won't hold the speed as well. We typically run 1200 lbs of ballast (and lead) + people (another 600-800 lbs).

I'd like to add another prop to the arsenal...either an Acme 1464 or 1236. I know the 1464 will get out of the hole faster, but do I really need that aggressive of a prop, or would a 1236 be sufficient?

Thanks.

I run the 1236 on my 01 SAN and it is great! I have run 2500-3000lbs at 4500ft and got on plane just fine. I typically run close to sea level and sometimes run 4000lbs and it still gets on plane pretty quick.

am considering a more aggressive prop myself. i have heard several recommend the 1464 and i see white lake offers the 1234, both of which are .105 cup with an inch difference in diameter. thats the first ive heard about the 1236 with .150 cup, am wondering which is most aggressive ? im guessing the 1236, but am probably wrong on that ... anyway, then on to where the best deal might be had on one ???

[OKWAKEBDR]

1234 will not fit a 2003 SAN. The diamater is too big.

Best deal I have found is Delta Propellars with the PN discount.

The 1464 and 1236 are the exact same diamater and pitch, just have different cupping. The 1464 is .105 cup; the 1236 is .150 cup. I understand the diamater and pitch measurements and how they affect performance, but I don't really understand the cupping. I'm guessing more cup = less "slipping" which would mean that the 1236 would be a slight bit slower out of the hole than the 1464, but may have a slightly higher top end speed?

[obd666]

thats interesting because they have the 1234 as a direct replacement for the 644, which i had been thinking was what came factory on my 03 (without having taken it off to confirm of course ) ?? i know it is an inch bigger though like you mentioned ... anyway, im with you regarding the cup metric as i dont exactly know its effect on performance. i would think the .150 of the 1236 would grab more, thus being more aggressive. but you're right, it would also seem that it would be slower so im not sure good info though, thanks

The explanation I was given by Acme when I called about a new prop was that the cup would give a little better fuel efficiency. By the prop grabbing the water and not slipping it is spinning less RPM's which equals less fuel consumption. You could argue the other way around to with the 1464 getting out of the hole faster, if it does. The only way to settle this is with an old fashioned duel!! Anyone with the 1464 and GT-40 want to have a sacked out drag race to 24mph?????

Acme told me the 1464 is more aggressive.

I'm not anywhere near the altitude you are (660 ft) but I love my 1464. It was a night/day difference from the 644 I was running. I can't really see thee being much of a difference between those two props. I guess it really comes down to how far do you go to get to your riding spot? If you drop the boat in the lake and start riding or do you need to run for 30 minutes or so to find good water. I may want more economy if I had to drive a bit to get to my riding spot, but if it's basically right at the ramp there's no need for economy IMHO.

How much is .045 cup really going to make after all? I wouldn't think it would even be noticeable.

So the 1236 is better overall? I am going
to Powell in a couple weeks. So long drives will be on the menu. What prop is the stock 2003 SANTE?

[core-rider]

536

With either of those props youre looking at straight up holeshot rather than any kind of top speed or fast cruising. I pretty much only go about 25 when rolling to the riding spot. With the 1236 im above 3500rpms at that speed. At 30 im above 4500rpms.

seth, I run the 1465 (which is the same as the 1464 except the prop rotation) on my 08 210. I had the 645 from the factory. There is no comparison between the two props for hole shot. I also disagree with what Acme told you about the fuel efficency if you are running a sacked out boat. My 1465 gets the boat up to wakeboarding speeds so much quicker with less drag that I get a lot better fuel economy out of it. When running the 645 with the boat loaded up I couldn't even get on plane unless I had people moving to the bow of the boat.

core-rider, I had approximately .020 cup taken out of the 1465 that I have and noticed a difference from what it was originally. That being said, my 1465 is not a standard 1465 anymore. It is a 1465 with about .085 cup.

I was talking about the 1236 vs. the 1464.

What is top speed with the 1464? I am looking for the best overall prop. For slalom wake and surf. I would also like to be able to go atleast 40mph.

[obd666]

is a good point and what my concern is. i definitely want the big torque when loaded down, but would like to know it will easily go 30 - 35 when empty without turning big RPMs

[core-rider]

IIRC, I run about 32-34 MPH at 3500 RPMs. I don't push the engine much harder than that for extended periods of time. You may make 38-40, but it would be at the engine's "listed" rev limit I think.

Bimmer, I think you need to stick with a 644 if your looking to go that fast. That's what I had and it is still my back-up prop. It would get my boat out of the hole, just took more time than the 1464. My plane off time weighted dropped big time and the engine doesn't have to work nearly as hard doing it.
