SKY,
PM sent earlier. I was having a difficult time finding this thread. Here is the question: Where does one acquire the special fin extration tool? Direct fro NIAD?

I heard they would rent or loan them.

After reading a few more threads, I called and went ahead and purchased direct fro Niad in Connecticut. So, if you have a need within a reasonable distance from Memphis or Pickwick lake on the Tn river, I will have one in a few days.

What is the cost?

Sorry. I missed the PM.

Yes, Naiad has the tool. It is just a hardened jack bolt.

Order the seals, the retainer ring and new screws for the ring as you may need them.

Getting the fin off is often the most difficult part. You will need a long extension on a 3/4" drive ratchet.

What is the cost?

The cost is $386 for the tool.

The fins fit up on a locking taper - no keyway.
With the centering pin in place, lift the fin up into position and barely snug the bolt. Measure from the center of the leading edge and trailing edge of the fin to the keel. Adjust the fin angle until both measurements are the same and tighten the bolt. Remove centering pin and you are done.

If alignment is fine before you pull them off, just trace around them with a Sharpie onto the hull. Then line them back up with that outline and you don't have to measure everything.

This is a very useful thread. I will be tearing mine down shortly. Good chance it will need bearings and races. If so I will continue where Sky left off.

Appreciate if anyone knows where to buy the hardened steel bolt and the hard hydraulic tube that plugs into the bolt to jack the fin off the taper?
