# How to draw a propeller with TikZ?

I want to draw the propeller, which is mixing the water in the pool.In attached file you can see my drawing. How can I develop this drawing?

\documentclass[tikz,border=5]{standalone}
\begin{document}
\begin{tikzpicture}
\draw[line width = 10pt] (-0.75,0.5) -- (-0.75,-2.75) --
(3.0, -2.75) -- (3.0,0.5);
\draw[join=round, line width = 5pt, color = gray!25] (-0.75,0.42) --
(-0.75,-2.75) -- (3.0, -2.75) -- (3.0,0.42);
\draw[join=round, line width = 10pt] (-1.5,-2.75) -- (-0.85,-2.75) ;
\draw[join=round, line width = 5pt, color = gray!25] (-1.5,-2.75) -- (-0.7,-2.75) ;
\draw[join=round, line width = 10pt] (3.10,-2.75) -- (3.75,-2.75) ;
\draw[join=round, line width = 5pt, color = gray!25] (3.00,-2.75) -- (3.75,-2.75) ;
\fill[gray!40!white] (-0.57,-2.57) rectangle (2.83,0.0);
\draw[rounded corners=2pt,fill=black, ultra thick] (0.8,-0.5) -- (2,-0.4) -- (2,-0.6) -- cycle;
\draw[rounded corners=2pt,fill=black, ultra thick] (1.2,-0.5) -- (0,-0.4) -- (0,-0.6) -- cycle;
\draw[join = round, ultra thick] (1,-0.50) -- (1,2.5);
\draw[-latex,thin](-1.5,-1.50)node[above,scale=1.0]{\scriptsize{$25^{\circ}C$}} to[out=-80,in=150] (-1.5,-2.70);
\draw[-latex,thin](2.0,1.0)node[above,scale=1.0]{\scriptsize{$90^{\circ}C$}} to[out=-80,in=100] (2.0,0.00);
\draw[-stealth,thin](0.75,1.25) to[out=-80,in=-120] (1.25,1.25);
\end{tikzpicture}
\end{document}
• Some people take exception to questions of the form "Please draw this for me". You will get more help if you post some code showing what you have tried and give a minimal working example. – Andrew Mar 21 '16 at 12:13
• what does a propeller look like? – percusse Mar 21 '16 at 12:28
• @flav then OP will come and say oh is it possible to draw it from the side view? and then endless fun... ;) – percusse Mar 21 '16 at 12:33
