Lake-X tried several lab finished props from several prop shops...York Propeller beat them all even Merc's own. Tommy at Warlock Perf Marine said that when it comes to lab finishing, they have tried several of the well known prop shops and no one that they have found yet does a better, more consistant job than York. We have compared York's prop to Merc's and you can definately see the difference. Also, York gets about $175 per prop vs Merc's $350+. Call Tommy at WPM and he can give you the scoop.
