I went with Galvanized and love it! Launch is a one man job now no sweat.
They are great to deal with and even delivered my trailer on a Sunday!
Gerry from Kaygee links to them from his seamax site.
As for outboards I use a 9.9hp Honda and it is Perfect for my Seamax HD360.
Just my 2 cents (I am not affiliated with any of these companies. Just a happy customer.
Cheers.
