I don't have any picts but when I got the samco stuff they didn't offer the clamps that samco says work best with their hoses. The store @ the reg site has them now, though.
My 90 had the sprung steel clamps and I believe there was a service issue about loss of coolant from the "ideal" type screw clamps and that's why the factory decided to use the sprung steel clamps.
I notice with my 90, that having used "ideal" screw type clamps that I bought at the local marine supply store because of all s/s materials..not just the band or just the screw but both....that I'm loosing some coolant vapor upon completion of a "use cycle"....I smell it & can't see any leaks & if I use my p-tester on the cold system everything is tight...that kind of backs up what the factory was saying about the screw type clamps....I live with it
