A factory produces a certain product, with the daily cost $C$ (in yuan) and daily production $x$ (in tons) satisfying the function $C=3+x$. The daily sales revenue $R$ (in yuan) and daily production $x$ satisfy the function $S= \begin{cases} 3x+ \frac {k}{x-8}+5, & 0 < x < 6 \\ 14, & x\geqslant 6 \end{cases}$. The daily profit is defined as $L=S-C$. When $x=2$, $L=3$.
(I) Find the value of $k$;
(II) Find the daily production quantity that maximizes the daily profit and compute the maximum profit.
