For future reference, it's good to know that if the shifter binds up again, I can pop the four bolts off the side of the transmission and free up that part without having to get the whole gearbox out of there.  Though it may be a good idea to pump the fluid out before taking it off, unless you want to leak fluid in your bilge.

We noticed one of the seals on the gearbox was leaking badly so he's ordering a replacement set while it's out.  It's also good to know that the gearbox, which got seawater inside, is otherwise okay.

I think that you have to take the whole end cap off and then install them but don't hold me to it. That is on my todo list though.

What part is cracked, the stainless or the aluminum part of the gooseneck?  If it's stainless, I'd take it off the mast, grind out the crack and refill it with a stick welder, then grind it flat again.  Stainless is a really poor heat conductor so it warps all to hell when you weld it.  I'd guess when it was welded they left some internal stresses in the parts.  How old is it?

I have found two things that help a lot... actually three.. one is a clothes hanger with a hook bent into the end.. The next one would be one of the extending magnetic pickup tools. Third is a long grab claw with the claw on one end and the hand grip on the other that you squeeze to get the grabbers to close. The only thing I have permanently lost down there so far was a stainless washer that the magnet thing couldn't get a grip on.

 

Our goose neck had to be re-welded on the port side where the original weld started to crack. Since it was re-welded it has seemed fine. Original welds looked pretty but I'm assuming someone didn't use the right current or something when welding it as the weld must have been a bit brittle there.

After I got in there it wasn't so intimidating, I haven't gotten a call from the dockmaster telling me that the boat is sinking, so that's good too.  I did all this in the marina without the help of a boatyard so it's good to know that I can get to the engine in a pinch without needing to have vessel assist tow me.

 

The good news is that the transmission repair shop actually turned around the repair rather quickly.  Evidently the gearbox and clutches are fine, but the shift assembly had some corrosion in it that prevented it from operation.  They dunked it in some diesel and I guess it's bench testing fine now.  So I know my project for this weekend -- getting that back in the boat.

 

I went and picked up one of these today which should help me align the engine back on it's mounts. http://www.harborfreight.com/1.....t-996.html  If I were to do the project again, I'd probably use this from the start.

 

I'd offer to help you with your engine, but I sadly live on the wrong coast....ha!  I guess my next project is rebuilding the gooseneck when my new welder shows up!  Happy sailing.

I know in a few years I will have the engine project and am not looking forward to it.
