| Hi I'm new to these boats and well boats in general, I bought a 78 correct craft that was missing the rudder. It seems after searching everywhere that they are very hard to find, but as luck would have it I found one in my area for cheap...so I rolled the dice and bought it. I was hoping that someone could tell me where the part number is located because this thing doesn't have any markings on it anywhere I can see...and I believe I'm looking for "11a" is that correct? |

Jack, Chances are high that the 11A is correct since it was used on most models in 78. What model CC did you purchase? You probably won't find a # on it. Post a picture so we can see what you purchased. Doe it fit the port on the boat? ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

| I just bought the rudder so I haven't tried to see if it fits...my boat is a 78 correct craft ski tique I believe...the guy said the rudder came off a 87 but he wasn't for sure of it being that year ...I was hoping he mixed the numbers up lol...trying to figure out how to upload a photo |

Hopefully you got the right one. Your ski tique takes a 27 A rudder. It is smaller than the Ski Nautique 11A rudder Pete mentioned. To see which one you have, the 27A has a 1" shaft, the 11A, a 1 1/4 shaft. If he was right about his rudder coming off an 87, you probably got the bigger 11A, as I dont think any boats had the smaller 27A at that point, as all the 16 and 17 foot boats were done. ------------- _____________ “So, how was your weekend?” “Well, let me see…sun burn, stiff neck, screwed up back, assorted aches and pains….yup, my weekend was great, thanks for asking.” |

| Wow that's great info...just got it home...it appears it may fit both port and shaft measure at 1 1/4 so it is the larger one...I will say my boat is 18ft ...I didn't get a title with the boat I wonder if the guy who sold it to me was mistaken. How do I add photos? |

Are you saying you dont know for a fact that it is a Ski Tique vs a Ski Nautique? If you are sure its 18 feet and sure that larger rudder fits, and you're sure its a 78, then it sounds like it is a Nautique (or similar). Is there no badge on the dashboard to indicate model? To add pictures, you really cant be on a tablet or phone. If you can get the pics to a desk or lap top, hit the Post reply button with the down blue arrow at bottom of thread, a new reply window will show up. It will have an icon with a tree and up arrow. Click on that and select picture from your computer then follow instructions. ------------- _____________ “So, how was your weekend?” “Well, let me see…sun burn, stiff neck, screwed up back, assorted aches and pains….yup, my weekend was great, thanks for asking.” |

Why don't you post the HIN number for the boat? It'll resemble the example below It'll be at the upper right hand corner of the transom just below the rub rail. That will with a little deciphering, tell what your boat is and help figure out if the rudder will be the right one.. If you can't post a picture just type it out

That's a tique with a Nau in front of it So in other words, it's a Ski Nautique and your newly bought 11A rudder should fit right into the rudder port that's in the boat now. |

   the shiny prop is new ( wife cleaned it up nice) but its a 13x13 and the old prop came off the boat its a 13x14...does the difference in number matter? |

Either could work. Try both and see which performance you like best. First number is diameter, second number is blade pitch (in inches) it is the theoretical distance the propeller will advance in one rotation. Higher pitch travels faster (i.e. greater distance per revolution) however, higher pitch is more resistance, so will slow engine down a few RPM. Its a balancing act to get the optimal performance. ------------- _____________ “So, how was your weekend?” “Well, let me see…sun burn, stiff neck, screwed up back, assorted aches and pains….yup, my weekend was great, thanks for asking.” |

| That's great news!! I didn't want to use old one...if you look close it's been peeled back from where (what the guy before me said) it was launched in shallow water and the rudder caught ground and spun around causing it to hit the prop...hence no rudder and peeled prop...thanks everyone for all the help and tips!! |

Is that the photo/camera angle, or does that 11a have a light bend in it??? ------------- 84 SN Sold 98 SN Lund Pro V 1975 Alumacraft |

| I was hoping someone wouldn't say that without me mentioning it...it does seem to have a weird sorta bend to it...it also seems to have a flat surface on the back end of it on one side and a rounded over surface on the other side almost like the wing of an airplane...hope it's useable... |

Welcome to CCFan Jack and congrats on the New to you Nauti! Glad you found us and even though it looks like you've got quite a bit of work to do on the boat, you'll be glad you did in the end. Old boats are just cool and in a modern day world of Surf Machines and pimped out rides Old School is Cool.! Looks a little bent to me as well but don't fret. It's a slight bend and can be used if it's not binding once you install it. Keep in mind that it can be straightened. I've bent a rudder before and the guys at Delta Propeller were able to fix it. Keep us updated on your post with the progress and a stupid question is one that isn't asked. Check out the FAQ thread on the site as it's VERY informative and can direct you to topics that have been discussed in length here on CCFan by guys who know their stuff. Use the search function when you can and if you still can't find an answer then ask away. Again welcome to CCFan!  ------------- "Morfoot; He can ski.

Jack, The bend can be straightened. If you don't have access to a hydraulic press, then a machine shop with one can do it. Some prop shops can as well. I wouldn't worry about the irregular surface. Rudders being a rough casting have never been that precise. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Welcome. Boat is Good find,and glad you found ccfan These guys can provide priceless excellent info for your restoration So you can relax and enjoy I see no carb, probably need a marine type for safety as well as alternator should have screens over openings (not at Orielly) |

| The man who sold me the boat had robbed carb off of it but when I mentioned it he put it back in boat (it's in the picture of the dash with a hose and funnel I was using to get motor to kick over before removing it again) the carb is an Edelbrock 1407 I believe...not sure why you mean about the alternator but I'll go look at it in a moment ...I've got a no spark issue I'm trying to figure out...I replaced the coil last night but that didn't fix it (coil had a bad primary) now I've got the distributor out and disassembled...hoping I can find some points and condenser at a parts store just to get it running....I'm not super familiar with these engines (I'm 33) only experience with these I have is my 66' 383 charger project that's currently sidelined because I have lakefront property now lol (family demands a boat and 5 yr olds can be ruthless!) |

Here's a little something on how to identify an Edelbrock carburetor You might find a number like 1406, 1407, 1409 or 1410 for example

Sounds to me like somebody did some rudder tuning on that rudder at some time over the years to affect the steering feel/characteristics. You can do a search on "rudder tuning" or "rudder filing" From the factory they were the same on both sides It's usable |

| Yeah it is literally flat on one side and rounded on the other...I think by the end of the day I might have this thing running and together...maybe next weekend will be boat day! Getting really exciting now. |

If you go to NAPA or some marine place, assuming it's the original prestolite use these numbers points 18-5303 condenser 18-5347 NAPA and Sierra part numbers are the same, the NAPA brand stuff is rebranded Sierra stuff in this case. You can also cross reference those numbers to whatever brand the place may carry

An automotive alternator will have vents open to the inside of alternator A marine alternator usually has a fine screen covering those vents opening to prevent sparks in alternator from escaping and causing fire or explosion |

Get that boat out from under the trees for Gods sake and if your wife sees that rudder in the kitchen your gonna be in big trouble mister. Nice rig, Got a '78 myself. ------------- Jesus was a bare-footer............. |

| It hasn't been under the trees but a week or two...my yard is starting to look junky with all the projects I got going on lol...had to store it there...but good news!! I got the motor running (idle) so hopefully it won't be there long...I need to rebuild the carb and investigate the throttle issue...it's either all or nothing on the throttle right now lol...you have a 78 can you answer 2 questions for me....I found this one was lacking a blower motor (completely gone) so I purchased a new 3" one with 8 ft of line...but I have no idea where to mount it...should it be close to tank to evacuate fumes or more near the motor....I also noticed the bilge pump is located under motor but it seems more water collects near rear and I'm not sure if the guy before me just put it under motor or if it's supposed to be there. |

Hi Jack. The blower lives up under the stern cap and to port a bit. Find and follow the yellow and black wires. They end at the blower. The discharge should engage the louver air box seen on the transom exterior. Blower suction hose gets routed down and along the inside of the port stringer to just under the reversing gear. Bilge pump is where it should be. ------------- Jesus was a bare-footer............. |

| A https://www.ridetheducksofseattle.com/rudder-on-a-boat/" rel="nofollow - boat’s rudder system is almost always at the stern, which is the vessel’s rear. They have a straightforward look – a large, flat surface, sheet, plate, blade, or fin connected to the vessel at the rear or aft section. |
