Mayfair extension box
 

Has anyone used the bravo Mayfair extension boxes? I know the Imco's are very popular but I can buy the dual Mayfair kit for almost half of the Imco kit...

I may be out of the loop on this, but was a "Mayfair" extension box ever manufactured for a Merc Bravo One outdrive? If so, I have never heard of them. Perhaps you are thinking of a Stellings extension box---yeah?

Ya, if you go on CP's website they offer them for bravos. It looks like you have to re drill the transom if I am reading their instructions correctly. It also looks like the exterior bolts are exposed rather than concealed like the imco's.
