Ricko, Good luck with the surgery. Hope it all goes well without any problems so you can get back in that boat!
I can only think of one thing regarding the shop wanting to reduce the number of wires. Some times through the life of a boat, things (with wires) get added on or problem are corrected by adding wires without much thought. I've seen some real "rats nests"!! Maybe the shop wants to start over with the wiring to clean it all up. Considering your ground problem, that's not a bad idea. |

Ricko,
I'm in SW VA, which isn't as far from you as you might think. I also have a '69 Barracuda with a Chrysler 318. Mine got a Dakota truck block, too, but I made sure I stayed with reverse rotation. That meant a special cam, since I used a roller cam block. Judging by your posts, I'm betting that doesn't mean much to you, but I encourage you to hang in there. I started reading Car and Driver as a young teen and didn't understand half of what they were talking about, but eventually I caught on to the specialized terms. Do some searches on this site and you might find answers to the puzzles and extra missing pieces in other threads. As for my prop, I went oversized and don't regret it a bit. I'll have to check the size and brand. I celebrate the day I whanged the tiny original prop on a very solid rock and destroyed it. The prop, not the rock. Performance went steroidal. Final note: when my boat "slipped" it turned out to be a seriously trashed transmission. After a couple of rebuilds, I finally opted for a new tranny, and haven't looked back since. |

Good Evening my Friends,
It has been a crazy summer and my apologies for not being on lately. Had a problem with the ole boat. Seems one of the ground disintegrated. I had to take her in to the shop where they put on a new coil, new module, and did something to the distributer. Nothing worked. The boat would still not fire. After tracing about every wire, they found a ground that had essentially withered down to nothing. They did some re wiring of the boat and it is running good. Real good. They said I should bring her in over the winter and have all the wires re done. They also said they wanted to do something with the ignition to reduce the number of wires? Any thoughts on this one. Any way, I took her for a spin and it was great to be back on the water. Next problem, Ricko is having surgery next week so my season is about over in a week. I will not be allowed in a car for 4 weeks, I asked the Dr. if that included boats, he didn't find it to funny. I did hear some good news for my fellow owners of these awesome boats. Seems the value is steadily rising as first fiberglass boats are now becoming more and more people are looking for. I am going to bring her back to orginial and keep it that way. It's All Good has been a lot of fun and I enjoy having her. Take care and have a good evening. Ricko |

Pete, just to throw a wrench in here- I have what appears to be a 13" prop on my Skier. Hull clearance is ~1/2", maybe less. No vibrations to speak of at all- and the boat runs strong. I have no idea how long this particular prop has been on the boat (probably not long), but I have no markings or discoloration due to the minimal clearance, let along any damage. My plan is to swap it out for a 12x13 OJ as soon as possible, as I think thats the ideal prop for the boat- but it just goes to show that every boat responds a little differently.
If the OP has 1" or more clearance with the Acme, I say run it and see if you like it. I bet he will. My guess is that it will leave some top end on the table compared to the OJ, but all around performance should be awesome. |

Ricko, I'm going up north for a week and will be taking the 540 that didn't work on my Tique with me. The plan ever since I tried it on the Tique was to try it on my friends Barracuda just to see what happens. I'll take some pictures and post them a lond with the results. It should be interesting!!! I'll have the results after the GL reunion.

Quote by Woody: "Replacing 12" Props On the older non-Nautique Correct Crafts (like my Mustang) that came fitted with a 12" prop, you can move up to a 13" prop. Woody from Southeast Correct Craft recommends there be a minimum distance between the prop blade and the hull equal to the shaft diameter or there can be damage to the hull gelcoat over time. After you have installed your new prop, measure at a 90 degree angle from the shaft at the point where the blade is closest to the hull. If the distance is less than one inch and you notice extra vibration or at the first signs of marking on the hull right above the blade, you can send your 13" prop back to Acme and they will trim a little off each blade so that it fits you boat properly." Ricko, I'm one of the guys who had bad luck with the 540 replacement for a 12" prop. The vibration was so bad that I knew what was going on and only ran it for about 20 minutes! Trimming is not a option as far as I'm concerned. (and others) Why buy a fancy CNC prop and have it turned down - get a OJ prop instead! BTW, I really don't think that Acme is as "tuned" into the older boats like they would like you to believe!! |

WOT Wide Open Throttle .I dont know about youre specific boat . But I believe you should be running around 4800 rpm at wot .
Also if im not mistaken the acme props have a different rake to them . Which would put the blades on the prop back farther than on {lets say an O.J.} Which will increas the distance between the hull and the blade . You should have the same distance between the prop and hull , as what the thickness of your shaft is .Therefore if you have 1 inch space then you are ok .You still need to check your WOT to determine if you have the proper pitch . I believe if your not running an Acme , you should run a 12x14. This was the most common . |

Good Evening. There is 1" from the top of the prop to the bottom of the boat. I am really spooked at this point. I took her out tonight and opened her up. It felt like something was slipping. I slowed up and brought her back to the dock and trailer slowly. Checked the prop and it was on fine, I pulled on the shaft and it feels tight. Not sure if this whole prop thing has me scared to death.
I am upset because that last prop cost me $480 bucks. I don't blame delta. I just went in and bought what ACME Prop told me. I was told that they are the best by the Antique boat store in Cincinnati. I will call tomorrow and order a 12 LH 13 pitch. This will give me 1/2 more clearance to the bottom of the boat. Again, I have not run it wide open. But it cruises well at 3000 RPM. I have not felt any vibrations or anything like that. Since everyone is in agreement that I need a different prop, I will get it. Any other thoughts, please let me know. |

I bought the prop and bought the BS with it. I will call Delta Prop and have them order me in a 12". Funny thing though, I wonder if I had the right prop on it before. My boat has that rash in the same spot.
The guys from Acme Prop and Delta both said this was the prop. These are the people who are supposed to be the experts. I will take it back. Another trip across town. Thanks for the help!! |

Ricko, I found the other picture I was thinking about. It's on a Ski Tique and they were set up for 12" props. I can't tell for sure but it looks like it has a 13" prop on it. You'll notice the chucks of gel missing but also notice the large area where the gel looks etched. The prop burn or hull rash once through the harder gel, will erode into the polyester hull as well.

Ricko, They sold you a bunch of BS. I'm backing up both Steve and the Doc. That Cuda should not run a 13" prop. Besides vibration/cavitation without the proper hull clearance, you will get prop burn on the hull. It's when the gel will actually get eaten away from the violent cavitation. I'll try to find the picture that was posted here so you can see what prop burn does. Are you just buying what they have on hand and used/rebuilt? It's time to get out your wallet and buy the correst prop. Do check the WOT RPM's.
I can't find the picture I was really looking for that shows the prop burn (some call it hull rash) but here's one. It's on a classic which is basicly the eary version of the Cuda. this erosion is mor around the rudder log but it does show what happens to the hull. Hull rash was so bad on some of the wood boats, that thin copper plates were screwed onto the hull over the prop and around the rudder. Get the correct prop!!! |

Ricko, I will bet the prop is too close to the hull.you should have at least 1" of clearance between the blade tip and the bottom of you boat.
This being said,you shouls have a 12" diameter prop on there,and from 13 to 14 " of pitch. Most of these old boats do not like a 13" wheel..... OJ Propellers builds probably the best prop for that boat and it is called the Legend.Just sent '65 Cuda one for his boat w/318 12x14 OJ Ledgend. After a weekend ask how his worked out. You RPM"s if correct are way too low/Wrong Prop..................Boat dr |

ricko,
Both of my cudas have 12" dia. props. How much room is there between the prop and the bottom of the hull? |

The prop they sold me was a 13 12 LH. He said putting on a larger prop would not make a difference. The folks at Acme said the same thing. I told them what I had and engine size and they said this was the prop. They also said they would do a one time change to the pitch if necessary. Hope that helps. I ran her pretty good the other night. I took her up to 3700 rpms and it ran great. I haven't dropped the hammer on it. Will do this weekend!!
13" Diameter 12 pitch that is correct!! |

Ricko, Hopefully you have got the prop on correctly - you sure don't want to go through this again!!! No, if you followed the prop install proceedure, the prop will be drawn up on it's taper and there isn't any kind of "seating". Go for it!!
60's hulls (as well as earlier boats) ran bow high. This is normal. It's not a I/O with a power trim! You said they sold you a 13 12. Typically the first number is dia. and the second is the pitch. Hopefully you have reversed the numbers. Please confirm that. The true test of proper prop sizing is the WOT. You really don't want that 318 to see much more that 4400 RPM. |

Well, the prop saga continues. I purchased another prop today at Delta Prop. They sold me a LH 13 12 with .08 cup. I put it on and took the boat out for a spin. It seemed to run pretty good. I noticed the bow seems to be a little higher, but I don't know if the boat was propped correctly to begin with. But as it stands right now, I am back on the water. Do you need to go slow for a bit to seat the prop, or just go for it?
I called Acme prop today and they told me to purchase this prop, and I was lucky that I live about 30 minutes from Delta Prop and they had it in stock. When I am at a good speed the RPM's are running about 3700. How does this sound. I greatly appreciate all help on this matter. Now that I know I am not the only correct craft person around, I look forward to meeting you all. I want to keep my boat original, and I guess I am going to have to re work her over time to keeping it original. I was told this Acme prop will give me better performance since it is not cast. |

Ricko, This was the first recommendation by steve (62wood) and I seconded it:"12" dia. Pitch in the 13-14 range"
Then you said: "They sold me a 12 RH 15 x 1". The 15 I feel will be too steep a pitch. Was the 15 a used one they had? Just trying to figure out how you ended up with it. |

Does anyone know the pitch for the prop? Delta sold me a 15 X 1 RH. Any thoughts would be greatly appreciated.

Wow, didn't see that coming. Many if not most of the folks who come to this site don't know that an older Correct Craft engine is typically reverse rotation. Accordingly, the group is always on the lookout to be sure folks get reverse rotation starter, props and other parts. There's a post going right now, where it appears the problem is a standard rotation starter was put on a reverse rotation engine.
An unfortunate mixup. I don't think very many people would have guessed the motor had been swithched out for a standard rotation motor. Most prop places will exchange the prop. BKH |

Pete, I could be the culprit,in my first response I made note to the RH rotation... never thought about someone changing to a car take-out ricko, what prop did you buy?(size/pitch) / where did you get it/ will they exchange it? sorry for the bad info.. |

ricko, Confirm that the engine is a LH. Keeping in mine that a LH will be counter clockwise viewed from the rear, looking at the front it will be running clockwise. Get a LH prop with the same diameter and pitch.

Well... The old prop is at the bottom of the river. It fell off. I went diving for it, but no luck. I do know that the engine did come out of a Dodge Durango, so I guess they did cheap out.
Any idea on the pitch or cup? Let me know. That stinks that they went cheap on the engine. I never knew that mattered until your post. They went all out on the Carb, etc. The engine looks good, real good. I guess I need to take it back to original. Thanks!! |

2 pages and no mention of the prop rotation!! Wow!
Ricko, Your boat should have a RH prop on it unless some one put another engine in it! Sometimes people will cheap out and put a "quick and dirty" LH block in from a car!! What does the old prop look like? Looking from the stern forward, a LH will turn counter clockwise in forward and obviously a RH will turn clockwise in forward!! |

HELP!! OK... I bought a RH prop as suggested. My dad did some work on the Shaft and was able to get the nut on. Big Problem. I put the boat in the water and reverse is forward and forward is reverse. I had the prop on correctly. Does this now mean I need a LH prop? If anyone can tell me exactly what I need to do, I would greatly appreciate it!!
By the way... 7 Days on the Ocean was absolutely great!! Thanks for the help!! |
