Hello Sailors

Buying a 2005 250 WB/CB

Did a scuba inspection to fix CB lifting line and to my surprise I found the port side CB shaft bracket hanging low, one bolt missing and the other about to fall out.

I hand tightened the loose bolt.

I was really hoping someone could tell me the size of those bolts so I could install the missing one and tighten them (is there a torq spec?) to prevent losing the CB...

VECTRAN line on order, used a nylon rope to pull up board so I can load on trailer (haven't seen the trailer yet) to clean and possibly paint bottom.

Is it possible to lower CB any when on trailer to install vectran line or will I need to do that underwater?

I will also remove (if not stuck) the bolts and replace all four and install the loctite to prevent backing out and seizure.

It's easy to do while in the water and (nearly) impossible on the trailer. Vectran 5 mm up-haul works best.

No idea what thread or bolt size that would be. Please describe which bolt is missing. A photo would be better. The center board mounting brackets are bolted with 4 bolts if I'm not mistaken

Hex head 3/8-16 x 11/4

Bolts were easy on trailer

Up-haul impossible on trailer.

Thanks

Both my keel hangers fell off while in my slip. I can tell that they were not installed correctly. See these links from Catalina Direct https://www.catalinadirect.com/shop-by-boat/catalina-250/hull-deck/keel/keel-hanger-casting-kit-c-25-c-250/ and https://www.catalinadirect.com/shop-by-boat/catalina-25/hull-deck/keel/pivot-assy/keel-fastener-kit-for-c-25-c-250/
This would probably require a haul-out and jack pads.

Also, I don't know where you are getting your VECTRAN from but this kit is available if you need it. https://www.catalinadirect.com/shop-by-boat/catalina-250/hull-deck/keel/c-250-keel-lifting-pennant-retrofit-assy/

Good luck.

Thanks for the info.

Here is a follow-up for future 250 owners

I've installed four Hex head 3/8-16 x 1 1/4 304 stainless bolts with locktite blue and will make this an annual maintenance item. I will be removing CB to checkout the bushing.

I ordered 5500lb vectran from West coast sailing. 5mm Samson Validator 12 Vectran Lin https://westcoastsailing.net/5mm-samson-validator-12-vectran-line/

My boat was already setup with the lifting tackle so following the diagram it literally uses bowlines to attach the vectran. The water is cooling fast so I'll get that lifting line inplace asap.

Watch for signs of hypothermia as you work in cold water, take frequent breaks to warm yourself back up. Allow yourself some time to warm up gradually during breaks. Wear a wetsuit.
As hypothermia begins to set in, you will notice that your hands and fingers will slow down, and you’ll fumble with parts and tools. That’s a sure sign.
Take care of yourself first, the boat can wait.

If your bushing is bad, take a look at my fix article that Russ made sticky. A bit time consuming but not necessarily hard. My bolts are probably original. When I bought the boat, one was backed part way out. I took them all out, cleaned them up and did the same as you are planning. Never had another problem. :- )

I reviewed the bushing repair before I got the boat and that made me feel comfortable that if a problem it could be fixed.

Been diving since 1980 and an Easter egg hunt in a quarry in PA made me decide to move south #128518;

Cold is realtive and our winter water in SC is warm realtive to your water in CT probably year round #128518; Thanks for your advice and caring #128077;

Seahunter, after I posted, I realized you were probably an experienced diver with lots of hours on the water. Here in CT we lose about 10-20 people to hypothermia each year for a variety of reasons, mainly inexperience or stupidity.
