Height for swim platform install

[jorgeinmiami]

I tried to install the ladder today but ran into a snag. It's a Sea Choice 3 step ladder

Although it came with the mounting hardware.

When I went to mock it up the ladder would not 1 clear the tabs as did not have enough of a angle and would go straight down. Seems like the angle of the transom and the mounting hardware did not let it work right.

Maybe a aluminum spacer behind the mount would be the trick. Looks like I need at least 3 inches for it to work.

Has anyone run into this problem?
