According to the doc string, it should read (mouse-wheel-mode 1):

,----[ C-h f mouse-wheel-mode RET ]
| mouse-wheel-mode is an interactive compiled Lisp function in `mwheel'.
| (mouse-wheel-mode &optional ARG)
| 
| Toggle mouse wheel support.
| With prefix argument ARG, turn on if positive, otherwise off.
| Returns non-nil if the new state is enabled.
`----

But apparently the only the mode is turned off if ARG is zero or
negative:

ELISP> (cons (mouse-wheel-mode 1) mouse-wheel-mode)
(t . t)

ELISP> (cons (mouse-wheel-mode t) mouse-wheel-mode)
(t . t)

ELISP> (cons (mouse-wheel-mode 0) mouse-wheel-mode)
(nil)

ELISP> (cons (mouse-wheel-mode -1) mouse-wheel-mode)
(nil)

ELISP> (cons (mouse-wheel-mode 'foo) mouse-wheel-mode)
(t . t)

Bye, Reiner.
