Help!! Trying to remove Pylon on ’83

I am doing my first stringer/floor job ever. My first major snagg is that I can not get the pylon out. I have searched this forum along with ccfan and the2001.com and cant find anything pertaining to that year nautique (I realize they are probably the same for other years).

Questions:
1. Am I correct?.....There is a brass looking tube coming out of the hull about 3" tall. There is a shaft that goes into this tube and has a bolt going thru the two to keep them together (I have removed the bolt.) Mounted on the top of that shaft is the aluminum pylon and there looks to be a roll pin that locks the shaft into pylon.

2. If this is correct, is there a secret to seperating the two? (I have taken out the 4 bolts attached to the engine cradle, mine had bolts, I think others have 2 U-bolts).

What I have tried...
1. soaking 2 days now with PB Blaster.
2. Tried twisting with Pipe wrench with 4 foot extension for torque.
3. Sledge hammer from every side to try to jar loose.
4. Pry bar using blocks of wood on the hull (I ended up bending the pry bar).
5. lifted boat with chain hoist on pylon (seperated floor from sides of boat more!)

The only thing I havent done, not for lack of trying, is removing the roll pin thing in the pylon about 7" off the hull. I have also managed to loosen the fiberglass at the base of the brass pole that goes into the hull (I will worry about fixing this later!)

next step....Sawzaw?????? If I do sawzaw it out, would i then be able to get this shaft out somehow?? Please Help!!

Thank you, and sorry for the long 1st post,
Lance

Also try to work with wrench below the bend so you get a clean application of force... you will put teeth marks in the pylon.

I havent pulled it out but it does appear there is a plate there, if it comes out (likely if its already loose) your going to need to remove the engine and transmission and then the cradle then pull the pylon out the bottom of the cradle to get the pylon, pin socket base and all to a big bench vise to remove. Since your doing the floors, and stringers anyway i would say get to it, pull everything cut out the plate and have at it. Better to cut out the plate carefully than to tear it out messily.

I have my 83 down to the stringers at this point myself waiting for the material to come in to replace them.

have you tried spreading the craddle under the pylon some? also are there screws going through a plate at the base of the pylon on top of the deck? not at the hull but the decking?

Got it out tonight!! I ended up grinding and chiseling away the epoxy around the bottom plate. The base is only about 2" x 3" or so?? You can see in the pics below that I did not have to grind away that much!



Now the next fun part tomorow is trying to get the brass piece off as I still cant get the pylon out of the cradle! Luckily, I do have at work a large vise mounted to a steel table mounted to a 52 ton machine, oh, and a 3' pipe wrench with about a 8' pole for leverage. Something has to give!!

Thanks for the help!
