Could someone provide insight with the following:

1) How to replace an existing turning ball located in an impossible to get to location and which seems to be permanently fiber-glassed into the hull

2) Does the turning ball need to be removed when installing a retro fit up-haul device and if so how is it done?

are you sure yours is actually fiberglassed into the hull. i have a '96 C250 and mine isn't. it has this inside the fiberglass tube. if you remove the exhaust hose you can see down there more clearly

i had to order a new one recently because the bronze sheaves corroded completely on mine and were frozen solid.

Thanks for the information. Unfortunately it seems, as per image below, we have the original turning ball which according to Catalina Direct must be removed before installing a new device.

Question is how to remove the original turning ball... any suggestions?

dunno. i would imagine that if it's glassed into the hull, it's likely that there is a bronze pin holding it inside a matrix of fiberglass. which too me say's the boat would need to be hauled and the ball cut out. i vaguely remember reading somewhere about someone doing something similar but it wasn't to a C250, may have been a C22 or C25

though for me the bigger question isn't how to get it out. anyone can do that. i'd be more curious how you get it back in!

the simple answer might be that you knock out the existing ball and retrofit in the assembly from the link i mentioned.

but i'm no expert, don't quote me. you could always try calling Catalina, i'm sure they've heard this problem before and might have a solution.

Hi Henk,

Here are the instructions from Catalina Direct for putting the turning ball conversion kit and removing the old turning ball:

I am attempting this today but it seems like a difficult task to reach and cut the old pin.

I let you know what I find out

With much interest we're awaiting your findings of

1) How to cut out, remove the turning ball axle and the tools you're using

2) Insert and install, as per blueprint shown, the turning conversion kit

Hopefully you're able to take lots of pictures of the procedure

Ok, I got the old one out. It was still turning but the alignment was off since the pin had worn a larger hole into the fiberglass tube.

This is how i got it out.

1st, I lifted the boat to about 3.5 feet up. This makes it a good level work under while seated

2nd, I used a hacksaw blade without the handle and added a point with a belt sander to get at the pin in the turning ball from underneath. All my power tools (dremmel, saws-all, etc..... would not fit up into the slot.).

3rd, I sawed for an hour since i could only move the blade back a forth an little bit especially at first.

After I sawed though one side of the pin and the ball would not come out I inserted a broom stick from the top and whacked the ball out from above using a rubber mallet. ( I did not want to spend another hour sawing the other side) It popped out easily causing no damage.

The new assembly fits inside the old and was easily installed and held in place by a pin (this time from the top inside the cabin).

Hopefully this will make my newly refurbished center board easier to lift and deploy with the full range of motion.
