A friend of mine has an Evinrude 6 hp (I think), with a add on weed cutter. It is what looks like a piece of machine steel about 1/2 by 2 1/2" sharpened on both 2 1/2" sides. It is epoxied onto the lower unit and extends next to the propeller (where it is still round). It runs quite closely to the round part of the prop. Does any body know where I can buy something like this, or am I going to have to fab it myself?<br /><br />thanks<br /><br />DougV>
