Thought I might as well ask here to see if anyone has a "spare" 540? Does OJ make an equivalent? ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1117&sort=&pagenum=6" rel="nofollow - 64 American Skier 62 Classic.. 73 Ski Nautique |

Hopefully Zach can help you out... but dont get your hopes up *too* much. IIRC, Delta's price (with the CCF discount and free shipping) is basically line on line with most dealers' cost. Add in Delta's liberal return policy and they can be pretty hard to beat. Ive had dealers try and do me favors and match Delta's pricing, and they simply cant do it. ------------- |

Tim, Somehow, momma doesnt see this in the necessity column like I do. Just starting to look early, been saving some coins up. Hopefully ready to pull the trigger on a deal somewhere. ... 9 degrees this morning...no urgency. btw, I've probably asked before, the 540 (13x12) over a 430 (13x13)? I know they arent the same, but I think the 73 is running a 13-14 Federal. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1117&sort=&pagenum=6" rel="nofollow - 64 American Skier 62 Classic.. 73 Ski Nautique |

Yes, you want the 540. You need a much higher hp engine and/or a lot more cubic inches to turn a 430, generally speaking. Not sure why some CC's shipped with larger props (my Skier came with a 12x15 instead of the typical 12x14, just like your boat would normally have come with a 13x13) but the smaller wheel (13x13 or equivalent like the 540) will improve performance in every way. And I hear you on cost... new props arent cheap! The 540 is worth the money though... and if Zach can do as good or a touch better than Delta (~$345 with the discount last I checked) then youre doing great. ------------- |

Al, The Ellis is what I've been running all summer. The 73 had a Federal 13x14 Super Cup when I bought it, but only ran it on the maiden voyage. She would just touch 49-50 on both speedos. (no gps) The trailer that the boat came with is for a newer/wider inboard. When I loaded the boat on the trailer the first time, somehow the boat dropped off one of the bunks and I bent the prop on the guard. I put the Ellis on and lost 2-3 mph on the top. The prop is not bad, but not perfect.. the boat has a bit of a viberation in the upper range. The bad thing is ,I have never run a tach (didnt work when I bought the 73 and I sent it out for repair.... 5 months ago, but thats another story: ,)so I dont know where I'm taching out at WOT. What prop are you running on your 74? ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1117&sort=&pagenum=6" rel="nofollow - 64 American Skier 62 Classic.. 73 Ski Nautique |

My favorite is the Ellis 13 x 14 Runs faster than a 13 x 13 and a 13 x 14 Federal. But the Ellis (my favorite) developed a slight vibration. Ellis now builds surface drive props. I keep meaning to call (during business hours) to see if they still service their old inboard props. |

Some of those Acme props are weird FYI. They tarnish very quickly and others stay shiny for long a long time. My buddy with the Malibu bought a bran new one and it looks like the oj before I had it re worked after one summer. My 540 still shines like a new penny so far. I had a 208 that had been opened and looked like it had some condensation water marks on it. I sent you a still sealed new one ;) ------------- |

Is the 208 a pancake prop? If you set it down on a flat surface, what does it rest on, blade tips or hub? If the blade tips, how far in the air is the hub? ------------- |

Must be a pancake Timmy. They told him if he wasn't barefooting and just driving the boat they would suggest the 208 with but 540 if he were a footer. Hope the 208 performs for him. ------------- |

Why must it be a pancake? The difference theyre talking about could easily be explained by the difference in blade count and pitch as well. ------------- |

Tim, I spoke with ( I think a Jim) at Acme on Monday. He said with the 270 Crusader and the way we use the 73, I would be "splitting hairs" performance wise with either the 540 (12 pitch) or the 208 (12.5 pitch). He figured the 208's top end would be within a MPH of the 540. Since Zach only had one 540, (and the 208 was a bit cheaper ) I decided on the 208. Like he said.. Either would be a big improvement over what I'm running and I will have a big smile with either! ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1117&sort=&pagenum=6" rel="nofollow - 64 American Skier 62 Classic.. 73 Ski Nautique |

My understanding was that the 208 was the 4 blade designed for the 240 horse 1:1 motors and that the 540 has a slight performance advantage it being the latest and greatest and bestest. ------------- |

Im talking about blade leading edges, not the trailing tip. If when set down, right side up (aft end of prop facing up), on a flat surface, a "normal" Acme prop sits on the blades- the hub is nearly 1/2" off the surface. A "pancake" prop sits on the hub. The only pancake Acme Ive tried is the 1868, but I did not like the way it performed at all. While it ran normal on my '90 (which plants the hull pretty much no matter what), it robbed 5+mph from the top end of the BFN by planting the nose at a much slower speed, and much more forcefully. Very disconcerting. I would not opt for a pancake style prop on a boat that runs bow-high (like a 2nd gen SN). No experience with a 208, but the 540 is a known good prop on that hull. If its a "normal" prop with an extra blade and 1/2" more pitch, then I would guess that Acme's assessment of losing ~1mph is about right, and that it would otherwise be worlds better than an old school hand finished prop. ------------- |

What I ment at the top was that the leading edge of the prop sits on it's hub. ------------- |

Date Posted: January-09-2013 at 1:28pm
I still dont follow. Do the leading edge of the blades touch, or does the hub? Or both? Its usually one or the other, and pretty obvious (once you know what youre looking for).  ------------- |
Posted By: phatsat67
Date Posted: January-09-2013 at 1:38pm
|
The leading edge (in blue) does not touch a table if it is set with the Acme 1800 number and down (leading hub side). So I assume it's a pancake style. So when the prop is set with the leading edges of the blades down it sits on its hub. ------------- |
Posted By: TRBenj
Date Posted: January-09-2013 at 1:42pm
... as shown in my picture, right? How about a 540? I didnt compare it, but believe the 540 should sit on the blade edges, just as a 430, 1458/1598, 490, 612, 654, 422 and 668 do. ------------- |

I only use the term pancake to differentiate between the more common Acmes that have proven all around performance on these hulls (especially top speed behavior) vs. the less common "flat" designs that Acme has made. Most other prop brands sit on the hub and not the blades when put on a flat surface- but Acme builds them a little different than Federal and OJ. I think the big difference is the amount of rake (which affects bow lift significantly) but Im not 100% certain. Like I said before, the pancake 1868 didnt perform outrageously on my NWZ hull. That boat runs planted no matter what prop I run. It did run slower, but that was more likely due to the low pitch/high revs than anything else. Maybe a pancake would be ok on a completely stock boat, but I personally would not take the chance of running one on a boat that rides bow high. Especially if you ever plan to throw some power at it. 540 rides great into the mid 50's... the 208 is an unknown quantity. ------------- |

But they may run pretty different!  If I were you Steve, I'd hold out for a 540 unless you got a good enough deal on it that its worth taking the chance on (and you can recoup the $$ if you were to sell it used). The pancakes perform very differently than the traditional Acmes, and not in a good way, IMHO. Pancake vs. conventional Acme (similar pitch/diam) turned our BFN into a 55-56mph boat vs. 61-62mph. The nose dive was hard and borderline violent on a hull that is otherwise pretty docile. While its doubtful you'd see such an extreme difference, Id still be nervous about running it on a boat that runs naturally bow high, even with a stock powerplant. The faster (stock) 2nd gens can flirt with 50mph and I wouldnt be surprised if your bowtie powered '73 is amongst them. Thats not a speed where you want something dangerous to happen! Just a word of caution. Im sure it would be worlds better than that ancient Federal in terms of holeshot and smoothness... and if you never plan to push the throttle down further than 45mph then you'll probably be fine. But if it were me, Id spend the extra to get a 540. Just saying! ------------- |

That 4 blade would be ideal if you put the tower back on the boat. Is the 540 a 13x12 RH? I put one of those on my brother's Century and it was a huge improvment over its old Federal 13x14.

Now you have me a "bit" worried. While I dont run extended WOT, I want to be able to do it and not worry about potential negative consequences. With the original Federal 13 x 14, both speedo's were just south of the 50 mph range. The Ellis 13 x 14 lost 3 to 4 mph... running in the 46 -47 mph range. The 73 is certainly capable of flirting with the mid century mark. I hope what ever prop I end up with will keep me in the high upper 40's, if not at the 50 mph range. When I spoke with Acme, Jim said I was splitting hairs as to performance between the two, but obviously, he is probably not familiar with the high speed handling characteristics of the hull. Dang, now you really have me wondering.... in your estimation, what hull would be a good application for a 208? ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1117&sort=&pagenum=6" rel="nofollow - 64 American Skier 62 Classic.. 73 Ski Nautique |

Steve, I'm watching this thread to see what your thoughts are on the 208 after you try it. That's what I have on my boat, and it seems to perform very well for my purposes. Which are wakeboarding and slalom. I get between 42-43 and about 4,300 rpms, but that's with less power and a slower/heavier hull than you have. No complaints, but I also have nothing to compare it too. I know Horkin, who never really comes around any more, was running a 208 on his warmed up Martinique and liked it. Not sure what he was getting for numbers though. I do know he was a lot closer to the 50mph mark than me, if not past it. |

Steve, not that I dont believe you, but those Airguides are only as accurate as theyre adjusted. Get a GPS on that boat! If its a slower running hull (some 2nd gen SN's run nose-lower and are only good for 44-45mph) then you may not lose much performance with the 208. Ive been somewhat disappointed with Acme's tech advice since Bill left (he was their lead applications engineer). No one else seems to have the same experience with the props- at least not the ones specific to Correct Crafts. Ive seen some interesting recommendations come out of them. Remember, Acme simply cant trial every prop on every potential application- they rely on customer feedback for their database. Along with all of the good data they get, I would imagine a lot of it comes from "Average Joes" who may not be as careful to collect good consistent data (accurate RPM and speed data, holding all variables constant when assessing differences between props, etc). I think the best advice youre going to get is going to come from folks passionate about props and these specific boats... ie, right here on CCFan. Brian, the NWZ runs so nose-planted that Ive found that the prop style has much less effect on running attitude (and thus, top end) than the nose-high hulls. The pancake 1868 returned "in-family" performance numbers based on its diameter/pitch on my '90, versus the "normal" Acmes. I wouldnt be surprised if you were to pick up 1mph with a 540 though, based on the lower pitch, 3-blade vs. 4, etc though. I suspect Steve would see a bigger difference on his older hull. ------------- |

Tim, I dont mean to "brag" about the speed, I never had a working GPS to use. I do now. I understand the actual speed and what the speedos report could be two different numbers... but thats all I have to go on for now. Other "problem" is the tach didnt work, (which reminds me to give Dale a call), so I dont know where the engine is spinning either. The combination of no gps or tach ,makes it kind of hard to establish a solid base line to start with. I will keep watching for that "smokin' 540 deal". One good thing, I still have a few months before I can even begin to think of getting her wet. I think I will start with the existing Ellis... gps and tach her and go from there. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1117&sort=&pagenum=6" rel="nofollow - 64 American Skier 62 Classic.. 73 Ski Nautique |

I am really curious to see what the 208 does so I can have better data for future potential customers. The 208's are cheap as I have had those on the shelf for a while. I just cant sell the props with Delta in the mix. If that 208 turns out good that might be an option for the 86 Chris' friends up in Iowa just purchased. ------------- |

I would bet that the 208 would be a better prop for a 2001 than a 2gen SN... Larger/heavier/slightly lower attitude hull that wont run more than 45-46 under ideal conditions (with a stock 351w and a 540). Steve, I know you werent bragging... and Airguides can actually be surprisingly accurate across the entire band, IF they are calibrated. Gotta find out if they are, first. Its too bad that the older ones are so hard to adjust... they were dirt simple by the late 70's (hex screw out the face, later a finger knob). Obviously you need SOME data to go on- if you had either a known RPM or speed, combined with a known prop (Fed 13x13 or Acme 540) there are enough people running that combo on your hull to fill in the blanks. Cant do it with too many unknowns- like that 208 or Ellis. ------------- |

Steve, I don't think that 208 will kill you if you are operating the boat in a matter it was intended for. ------------- |

Ive seen 2nd gens run 50 out of the box (actually 30+ years old and all stock!), so theyre no joke. CC didnt put speed limiters on them to keep them below 36mph. While they *might*not be far enough up the performance scale to do weird things due to a pancake, its not a totally outlandish possibility. At best, the boat will probably underperform slightly as compared to the proven 540- at least thats what my experince with the pancakes would lead me to believe. If paying new prop prices(even if nicely discounted), spend a little more to go with the proven prop- that was my point. If the 208 is yours and un-returnable, then give it a try. Having a known quantity along for a comparo would be nice too (like a 540) to be able to better qualify the difference in performance. ------------- |

That white boat was an undercover operation between Me and Yours Truly Chris Mars. I was very sad I didn't have a buyer for my boat or that would be in my shop right now. My dad was desprately trying to pawn off his MC to go buy that white beauty. I'm glad I could help out Chris' friends and check it out and help out the owner Jeff to get it sold. Jeff also has a restored 84 that was he and his wifes first boat. Its easily the nicest preserved 86 I've seen so far. ------------- |

Tim , as always I do apperciate your (and all the other CC guru's) input! Most of you have wayyyy more experience than I do. For the time being, I'm planning to keep the 208. (unless someone REALLY needs one! )It would be interesting to see how it stacks up with a 540. Maybe at GL or somehwere we can do a comparison WITH GPS and tach. Talking of pancake props. What I see in "height" difference between the 540 Jeff posted and my 208 looks to be pretty minimal (1/8" or so?). Makes that much handling difference? ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1117&sort=&pagenum=6" rel="nofollow - 64 American Skier 62 Classic.. 73 Ski Nautique |

HW, nothing wrong with that position, but neither is wanting to go fast just because you can. Im not tired of it- at least not yet! Dont you have a 380hp 351w ready to go in your MQ though? Some people may think that building a 50+mph (or 60+mph) ski boat is silly... thats ok, its not for everyone. I think its silly to suggest that a (new and expensive) prop will be just fine- "oh but dont try and go fast with it". At least if that was one of the reasons they bought it in the first place! But thats just me.  ------------- |

I don't think anyone witnessed our GL speed run out to the main body in Tim's BFN. 4 of us Iowa guys were tail weight when Tim punched the throttle over a set of rollers left from a 20' cruiser. I remember seeing the cruiser trolling along followed by the bow of the boat in the air and landing rather abruptly. That's probably the only time I thought seat belts would be useful in boats. Fun ride, but I'm surprised his rear seat vinyl isn't stained brown. ------------- |

Hopefully it'll be at GL with the new owners. If they can't make it I'm sure they'll trade me for the 96 that weekend. Zach was at it again with this deal. An "oh, by the way" turned into another Correct Craft in our extended ski family. I'm sure I'll spend some hours behind the wheel and at the end of a rope with this boat. Mark didn't know he has a salesman in the parts department! ------------- |

I never once had a bow dive (or chine lock or whatever you call it) in the 81 with either Amce prop (540 or 430)but those are both different animals than the 208. I had it happen a couple of times both with an OJ 13x13 at just above 50mph and that is a scary feeling. The OJ always pushed the nose down so it skied pretty good but the faster it went the less I trusted the boat in anything but glass water. Seems both Acmes were trying to lift the bow (or sink the stern), either way there was night and day between the styles of prop. Will be interesting to see what that motor will do in the MQ although I expect it to be propped for pulling a bunch of footers most of the time. Hopefully it gets run this summer or you should make sure it's been fogged. ------------- You can’t change the wind but you can adjust your sails |

Alan, my suspicion is that the 208 is a lower rake prop and will act more like the OJ's. The 1868 never caused our v-hull to chine lock but it nose dived hard enough to rob 5+ mph off the top (I could continue to power through it)... so Im thinking the same type of thing is at play. Agreed that it will be interesting to see how a v-hull compares to the 2nd gen SN speed wise- this will be a perfect comparison! My guess is that it will be pretty fast... a reliable 55mph for sure, maybe a touch more? I would say our BFN came to us with about the same amount of hp (~380hp) and it ran right there. ------------- |
