Some one else had adapted one to fit inside strut. Both are very cool.

Go back up to April 6 in this thread and Pete gives you a LINK to click on that takes you to Grants site. Really clever tool. Grant is out of StLouis, Mo. Really innovative guy and very interesting to talk to. BTW, he skied last year at 80 years young!!!!!!

Brilliant idea whoever thought of it !! I think I'll use that with my upcoming install. Need something to get the engine fairly close while setting the block in since I have all new mounts (and the originals were no help, since they weren't all that close to begin with)

Yes. I have 2 3 blades that have both been refurbed and not used yet. One is 13x13 and the other that came with the boat is a 13x14.

Can you guys help me confirm my shaft length so I can get the order in by noon for the new system? Otherwise I won’t get it by next weekend. It’s a ‘76 Martinique (seller told me it was a 78 until I got the title). There is a “50” cut into the shaft near the coupling, would guess that’s the length but don’t want to gamble.

Cole,
Your profile says you are a paper mill mechanical engineer. There are hundreds of couplings and shafts in a mill that require alignment. How do you align them? Maybe you could take a look at some and if you don't actually do the alignments ask someone who does for some first hand visuals and pointers. Does you mill utilize laser alignment on couplings and shafts? They sure are handy but unfortunately not practical on our small inboards.


The millwrights do the alignments and our engineering group has nothing to do with them. I am not the machining/mechanic flavor of ME either. If I knew someone here that would do the work for cash and not marina rates I would have just paid to have it done My work is in thermodynamic systems and fluid handling/metering and structural modifications. I have basically no tools of my own because my family had them all up north before I moved down here and I have been extremely rushed when trying to work on this for a variety of reasons I’m not going to post on here. I promise you I am much more competent than my posts would lead you to believe.   I am just not a 20/40/60 year veteran vintage correct craft mechanic. I do appreciate all the help from you guys.

It was Grant MacLaren and his band of old timers that did the laser alignment. There are pictures on CCF or maybe on Grant's website

Edit Here's a link to the CCF thread

Yes, Grant did use a laser but that's for finding the log and coupling center and not the actual coupling face alignment. It's just like CC uses to impress!

You can't measure the difference between the coupling faces when they are bolted together. If you have a gap between the faces when they are bolted together, then you have a major misalignment.

my confusion level and your post count are directly related.

Maybe he's only a mecanical engineer and doesn't do alignments.

Not to beat a dead horse, but any chance you are calling calipers 'feelers'?

I can't see how you could slide a feeler in between the couplers when they are bolted together.

These are

I was being a little dramatic about going hungry    I can swing the ARE. Wish I would’ve just bought it before (as recommended on every relevant thread on this site) and been done with it by now. On the bright side I will have a nice lever to use for getting the strut pointing due north.

If you had a straight shaft, Duane in Indy could turn it into a double taped shaft at a good price, but I suppose if it was straight you wouldn't need a new one

If you google      correctcraftfan general propeller     you'll come up with some reading about ARE and General Propeller.

In the interest of keeping you alive to use the boat, why don't you keep eating and check the alignment the right way before spending your food money? It won't take long to know if it's way out of whack

By the way you can probably save some of that money with a double tapered shaft from General Propeller in Florida

It's been discussed in some older threads here on CCF.

I'm trying to understand how you used the feeler gauges when the couplings were bolted together? The .003" max between the faces is the DIFFERANCE top to bottom port to starboard. As others have mentioned, try the boat out but understand with a .014", that's a lot.

Multiple big whoops took place. Throw out and disregard everything I said about the coupling faces. Couplers were bolted together and I missed a zero on the feelers. Duane I thought the same thing and that was why I didn’t like the measurement and did it multiple times. Sometimes the brain gets a little funny after 5 pm. I think my path forward is clear. I will just order the ARE now and go hungry now and thank you guys later. I got a quote from Elbert but should I just go through skidim to get the discount?

measured again and it was the same result. .0001 fit everywhere with a little resistance and .00015 did not fit anywhere.


Curious to find out how you measured these dimensions. I worked in Tool and Die trade for many years building aircraft engine inspection gages requiring that type of tolerances. Definitely controlled atmosphere type work.
