Crinmar no longer sells the glue for hull fairing seal for the sail drive leg , they tell me it was Bostik A3 . This glue is still available in Europe but not in North America. Apparently you can not air ship it - not safe . So I did some leg work and contacted Bostik for a north american alternative and they were helpful suggesting a product called 1685MC. It is a product used to glue those foam mops to the handle , works for rubber , leather ect. They sent me the Technical Data Sheet and it looks like it will do the trick. Available at Krayden in the US, I will try this summer and report if it works as they indicate . ------------- Unplugged # 164 NOTL |

That rubber gasket does take a beating. Whatever glue I use, I supplement it with 8 little stainless screws near the edge, grind the heads flat and fair over. Fletch replaced his rubber gasket with a 2 piece fiberglass cover. I might try this after my current one fails. js |

LSM is still selling the glue in Denmark. Their prices are cheaper than Crinan. http://www.lsm-diesel.dk/ Enter the part number 523A0000 if your keeping your boat perhaps buy a spare head gasket and fuel filter and impellor. The glue is a water proof contact cement. I've tried a few without success.

"Fletch replaced his rubber gasket with a 2 piece fiberglass cover." I like that idea.  ------------- Hull 147 - Angel's Share |

This is the glue Bostik suggests to replace their own Contact A3 that used to come with the factory seal . Still no guarantee it will work but given you can't air ship the original glue from Europe anymore I guess we will have to give it a try. To be clear you can buy it in Europe , you just can't legally put it on a plane to get it here anymore I am told .

I like the screw idea but I am hesitant to put a screw hole in the cored hull below the water line - it is cored , right ? Or is it solid there? As for the fiberglass alternative , it does not meet class and the drive does move around. ------------- Unplugged # 164 NOTL |

The description is "Bostik adhesive 1685M is a Neoprene Rubber-Solvent
based adhesive that shows excellent bonding
characteristics when bonding polyurethane foam and
abrasive grit, rubber to metal, wood to itself, leather and
many other materials. It has been used to bond cellulose
sponge to metal in the manufacturing of mops. It
provides excellent adhesions of cured and uncured
Neoprene and butyl membranes to concrete, wood and
metal." They did state it would work with fiberglass and also states in is properties "General: Flexible film with good
resistance to hot or cold water
detergents.
Weathering: Excellent
Chemical Resistance: Excellent to cold and boiling
water, detergents and aliphatic
oils." All I guess I can do is give it a try . ------------- Unplugged # 164 NOTL |
