I have just purchased the subject distributor. The gear does not match mechanically.
The direction of the teath are at 90 degrees compared to the older gear. Please advice: 1. Can the same distributor work with the opposite direction Gear? 2. If the answer to (1) is positive, can you specify the Cat. # of the needed gear? 3. If the answer to (1) is negative, how do you specify the required Distributor? |

what yr engine, and type of drive/tranny do you have?
if the gears don't match up then it's not going to work unless you replace the gears ar you sure it's not a DV model? ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

where are you located, can you take pictures of both, what was installed and the new one?
can you get a model number off of the old dist. Do you have a 1:1 BW velvet drive and a RH prop? or do you have a 1.23:1 PCM with a RH prop. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

No i'm not near the old one...
This is all the details i onced copied from the old dist' D3JL-12100B 2 D T PRESTOLITE IBM 7008AS R i dont know what trans i have but the prop is RH for sure. i just got summit on the phone and at first they said to replace the gear from the dist' shaft,to take what i have on my old one and to put it on the new, but i wasn't so sure about it and when we took second opinion from another technician the answer was DV isted of CV !! 79 that what you ment when you wrote DV? |

I don't think you have a 351W.
Was the prestolite distributor in the engine before? did it run with that distributor? What I've been able to find is the prestolite 7008AS is a 351C or 460 application and won't work on a 351W engine. The mallory unit is the correct unit for a 351W rev roation engine. The question is do you have a 351W and is the prestolite distributor the orginal dist out of the engine? ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

no, did the old dist come out of it and did it run with the old dist in it? personelly I think you have a 460 and not a 351 and that new distributor will not work. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

I did a search on the 7008AS number and it looks like it's a 460.
Look at the bolt pattern on the exhaust manifolds and see if they are centered side to side on the ports or centered top to bottom on the ports. another way to look at is, are there two rows of bolts per side or is there one line of bolts per side. two = 460 one = 351 ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

thanks 79
Tomorrow i will check this i have the PCMsvcmanual pdf and ther is adiagram on how to know what kind of engine you have by the model number and it looks like i have 351W,but now im thinking maybe one of the owners of this boat changed the engine and moved the metal part with the engine details... This is the details i have on the angine Pleasurecraft - v8 marine engine Model - PRD-WR-R10 Serial - 22528 Engine no' - 2c449aa-d22-2d22h |

look at the bolt pattern like I said that will tell you in a hart beat, whether it's a small block or big block.
The numbers really mean nothing to me and if the engine has been swaped then there meaningless as well. You could measure the dist base's and see if they match up exactly, compare the dia's and length's, helix location of the gear, oil pump drive configuration on the end of the gear, if everything matches up then you should be able to swap gears and install. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

Hi Yanivsai
Looking at the pictures in your other post, you most definitely have a 351W and you also have the wrong gear on the new Mallory distributor. I most definitely have a Prestolite right in front of me that has the same 7008 AS number and it came out of a RH rotation 351W engine and has the same gear as your old distributor. I'm not too familiar with Mallory stuff, but I do know that your gear is wrong for your engine's rotation. We'll let 79 nautique tell you what to do about gears for the Mallory. keno |

hi keno
First, thanks for your help What it means RH rotation ? i'm having truble to understand this.why the same engine will turn right or left ? and where,when its going out to the gear ? When i asked about the rotation of the distributor i think it was 79 who told me it doese't metter... Are you sure the engine in your case is RH ? How do i see if my is RH o LH engine ? yaniv |

Hi Yanivsai
Earlier you said "Engine rotation: When I look at the engine from the front of the boat backwards, all belts turn counterclockwise" This tells me you have a reverse rotating engine and you need a distributor with the gear cut the same way as your old one. What you have is a distributor for a normal rotation engine. If you search the posts you'll find out lots of info about reverse rotation engines and what parts are different. What is directly affecting you right now is the camshaft and distributor. All you need to do is swap distributors for one for a reverse rotating engine or get a new gear for the Mallory you already have. Due to the cam gear cut and the distributor gear cut, no matter which rotation engine you look at, the distributor rotor rotates counterclockwise when looking from above. It's confusing but what you need is the proper gear on your distributor and you'll be all set. I have no idea if you can swap the Prestolite gear onto the Mallory shaft or not. keno |

Model - PRD-WR-R10
The "P" means it's a Pleasurcraft The 1st"R" means it's Right Hand rotation The "D" means it's a 351 the "W" means it's a Warner Drive the 2nd"R" means it is a reverse drive the 3rd"R" means it's a right hand prop the "10" means it's direct drive (1:1ratio) Now the 351 has a 5/16 hex oil shaft. Make sure the one you get is for a 351. The 302 has a 1/4 oil shaft. In short, the 302 shaft slot is too small and won't work. You've got the same motor I've got and I just replaced my distributor. It was a great learning experience...  ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1520&sort=&pagenum=1&yrstart=1976&yrend=1980 - 78 Nautique If you're going to do it...

one of two things has happened, a problem with mallory's packaging, or you have a standard rotatation engine, From the other picture post it looks like a 351w engine, the helix's are opposite from the old to the new. So you may be able to swap gears if the shaft dia's match, mostly they do. The Second is to verify that mallory didn't make mistake. Can You take a picture of yout prop? ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

double check the part number on the dist and make sure it matchs what was on the box. And I still would like to see a picture of the prop. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

If you look at the pics of his new and old Distributo gears, the new one is for a standard LH motor. His original is a RH. It does look like the gears are probably interchangable. I'm with you, I think he can swap them. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1520&sort=&pagenum=1&yrstart=1976&yrend=1980 - 78 Nautique If you're going to do it...

Ok 79
Picter of the prop i hope to get in a day or two. I was thinking...keno said that all distributors turn ccw if you look at them from above. So,my engine with the pretolite gear will turn any dist' the right way (ccw) so if i'll change the gears from the prestolite to the mallory it should work right ? |

Hi Y'all
I think there are a couple of other possibilities here for mistakes. When I look up a YLU554CV on the Summit website it is for a normal rotation engine. Meanwhile they list the YLU554DV as being for a reverse rotation engine with an opposite rotation helix. They also list the YLM554CV(what yani has right now) for standard rotation and don't list a DV version of this at all. And then 79 nautique has a YLU554CV, maybe it's a CV with a reverse gear installed on it to make it work right. Maybe it came that way from Summit when he told them what he needed. Maybe you should verify it says CV on it and not DV. There are others here who agree that the old one is for a rev rotation engine and the new one is for std rotation Somebody is wrong here, beats the snot outta me who is, but it's obvious that yani needs the gear for the other direction. keno |

hi all
I was talking to summit 3 days ago and i told them that the ylm554cv is not the right part for me and while i hold ,they talked to a technician and came back with the answer i can chang the gears between the distributors. I asked him for second a opinion and he talked to another technician and came back with the answer that this technician had an old mallory book and what i need is not the CV but a DV wich they dont have. (i see now that they have the ylu554DV,but with no pic) so what i need is someone who have a ylu\ylm554DV to send me a picter of the gear so i can be sure that this is what i need befor i buy and spend another 100$ to send it overseas... thanks yaniv |

you guy's don't know what your talking about and obviously you didn't look at the mallory marine link I posted where it clearly states what model is what and I didn't swap gears on mine. Since Keno seems to have all the answers figure out the bullsh*t on your own. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

If you look at the picture summit has of the YLU-554-CV model the gear is like the one on your old dist. And if you look in mallory marine's catolog they list the ylm-554-cv as a RH. So I don't know where you got your dist or if someone has modifiyed it or not. I know what is in mine YLU-554-CV and it was installed without any modifications and works fine, I have talked directly with mallory " the manufacturer " and their catolog supports what I have stated reguarding the correct model and application. So do what you want, something is wrong and it's not my information that is wrong. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

Hey 79
I'm trying to play nice here, so you do the same and look and listen to what I'm saying. I ain't trying to start any pissing contests(I have seen your picture in Tim D's post though)and your replies. Unless I'm totally screwed up here the picture of the YLU554CV in the Summit catalog has teeth that go like this /////. There is no picture of the DV(we probably both agree on that) The teeth in Yaniv's picture of his old distributor go like this \\\\\. His new distributor goes like this/////. This doesn't look the same to me And we probably both agree that Yanic needs some help over there in Israel so let's get this hammered out. If I knew what I was doing with the computer, I could probably get both of those pictures in this post but I don't Later keno |

I agree with your statements regarding the helix angle, and the picture posted in summit for the CV version the gear matches what he pulled out, but the new one he has doesn't match the picture listed in summit for the CV version. My point is the model number I gave is right, what is in question is where did he get the dist and if there was a packaging error if it was brand new from summit. If it was from summit then I whould be asking why the picture they have posted doesn't match what they sent Yanic. Worse come to worse he should be able to remove the gear off his old unit and install it on the new unit and be good to go. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

Hi Again 79
The Summit picture DOES match his new one, Both helix's go like this///// What Summit sent matches their picture. Neither one matches his old one. That helix goes like this\\\\\ Do me a favor and look again at his pics and what is labeled as old(Prestolite) and new(Mallory) I'm starting to feel like I'm in a chat room or something. keno |

hi 79
First of all i want to realy thank you for your efforts.i dont take it as granted. The ylu/ylm554cv both have the gear cut like this //// and the prestolite i have is like this \\\\ and thats a fact. The number on the mallory dist' is ylm554cv and its new. Take a look: http://s32.photobucket.com/albums/d31/yanivsai/distributor/ In the pcm service manual they explain what is RH and LH engine by looking from front to back (pully)of the boat. RH - pully turns CCW LH - pully turns CW - LH is standart automotiv rotation - most of the engines are LH. My engine is RH. They also saing that all distributers in ford engines turn CCW regardless of engine rotation so i think thay are the same except the gear cut.swamp the gear and put it in. I have noticed today that the old dist' shaft have strange marks on it and he is 13mm dia. while the mallory is 12.8mm.its also been cut at the bottom end very ugly and was roughly grided. i dont think this is the original dist'. Im waiting for some aswers about the engine from PCM customer service at ohio. Again,thank you very much for the help.i dont think i could figre this one alone. I'll change gears and try it on thursday ,and i hope to ski that day. yaniv |

All ski nautiques prior to the 1.23:1 transmissin interduction are reverse rotation RH motors from the factory, with very few exceptions. personally I believe you have a LH standard rotation engine from a car and that's why the YLM-554-CV doesn't work. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

"The first r in the serial number indicates you have a right hand rotation engine. The distributor gear will not interchange. You will need to get the proper distributor."

your assuming it's the orginal motor, and if it is then the cv should have worked fine. I've already told you what the issue is, wrong motor rotation identification or a missed boxed distributor. Your dealling with a 25 year old boat and the odds of the thing being orginal is slim and none, show me a picture of the prop on the boat, not a new one you have bought, but the one that is on the boat that the old distributor worked with and then I will tell you if your issue is the dist or your rotation identification is wrong. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

Hey 79
Make sure you read the HEI distributor post that snuck back in here after a couple of years. It seems you have flip flopped from back then on what a DV or a CV are used for. Just trying to understand these Mallory's and get yaniv's problem fixed. keno |

Hi there 79
I've seen that before and it seems to think that every Ford out there is RH rotation and they don't make anything for a normal rotating Ford. Your answer also tells me you haven't really read or maybe comprehended anything that has been said so far. We know that there are distributors for both rotations otherwise think about all those poor Mastercraft owners out there. You even talk about CV's and DV's and your favorite catalog (Summit)lists both along with other places like DIM. Are you basing all this on what that Mallory page says. Come on use that experience you have Maybe you should go pull your distributor to verify what you think. Mine came out last night to verify what I think. I verified it, I'm happy. Well got to head out on the water. I'm done here keno |
