Rudder casting

OK I have been beating on, heating up, and swearing at the rudder pins ( brass). could this be OEM, did they come with brass? The gudgion screws came out like they were installed yesterday. When I removed the last of six screws I was holding the lower casting, expecting the unit to fall off but to my horror I saw that the rudder pin goes through the deck. So how do I get the pins to come out?

If you can't saw the pin off you can saw the back of the deck hole out. I know that seems a little extreme but, in the old days, racers would do that in an attempt to force more rudder rake. Both of my deck holes have been opened up. That hole doesn't really do anything as the gudgeon takes all the load. Don't be surprised if you can never free the pin either. I had to throw a lower casting away when an aluminum pin was forever corroded in place. My boat was left for many, many years in a saltwater environment with the pins in.

Thanks Sunvista,
The pins look pretty corroded, I put a block of wood and a bottle jack under the casting and beat the daylights out of the pin but could not get it to budge. I have about an inch of pin sticking up above the deck. I figured that if I could get it to move then I would cut it off just above the casting to remove the flared part of the pin. So if I cut the deck then there's no harm no foul?
I just want to remove the castings to repaint, and it would be nice to remove the rudders for trailering, but, @ 170.00 (each )new, I think I'll cut the deck and live w/ that.

You can use a hacksaw blade to cut the pin above the deck and on either side of the gudgeons to get the casting off without cutting out the deck.

MBounds, If I cut the pins how hard is it to drill out whats left, knowing that the pins are brass and the casting is aluminum?

Also, when gluing the frames togather, when I am done restoring the hulls, do I glue ALL frame parts? That is, all cross bars, side bars to the corner castings as well as the castings to the pylons?

i had the same problem with my starboard rudder pin. I ended up cutting the hole out on the deck so i could get serious with the pin. I soaked it for days in PB blaster and even gave it a little heat but nothing worked. I ended up giving it to my mechanic and he cut the pin and left only the parts that were inside the casting. He then drilled out the center of the pins to relieve some pressure and pushed them out with a hydrolic press. Even with the press he wasn't sure they were going to come out.

1) Once the castings are free from the boat, you can put them in a drill press to deal with the remains of the pins. Start with a small bit (1/8") and work up to the 3/8" diameter of the pins. You could also install plastic bushings in the castings which require a larger hole. That would eliminate the corrosion.

2) The usual glue job only includes the casting/pylon joints. You can glue/re-rivet the crossbar/casting joints if the rivets are loose. Do not glue the sidebars to the castings, since they are not structural and need to "float".

Once you get the pins out using the previous posts drill the castings and fit the Hobie nylon bushes and new pins.

Stops corrosion with the real benefit of taking the slop out of your rudders.

I did this and the difference is amazing.

man ... flashback ...

I had to do this last spring when I bought my 85 H16 ..

the good thing is the pins saw off pretty easy heh heh
