I replaced the
keel bolts on my 1989
Oceanis 390. I called the help number from the spareparts website and they told me what I needed, and took my details. Shipment was fast.
One thing about replacing Beneteau keelbolts - a lot of people have done it. You can do it in the
water if you do them one at a time. Also, and many others have had this experience, the heads can get so corroded that they literally go down a size. You are likely to find that once you get them out, the rest of the bolt looks very good. You'll need an impact driver, an impact driver extension (don't use a regular socket extension, they are too flexible), and a range of socket sizes. I didn't have to grind any of them down as some others did - in some cases I just used a hammer to drive the socket (carefully) over the corroded bolt
head. You'll need to put some anti-seize on the bolts as well as a good
sealant. I used butyl rubber wrapped around the bolt, and as the bolt went in, it squeezed out the butyl. Others use something like 4200. You'll need a torque wrench to set them in properly. Others recommend you go back to the bolts after a bit of sailing to torque them again. Then coat the top of the bolt with something to prevent rust - the bolts are mild steel.
Good luck.
