Will the machete lll work on a trolling motor that has a machete ll on it? The machete lll is the tapered head design and the machete ll is the older design like the aluminum props. It is a 2002 model motorguide brute with a 3.5 inch hub. Need to replace the one I have .It is getting bad. The machete ll is hard to find and I like the tapered head design of the lll anyway. But not sure if it will work by looking at pics. Thanks for any help on this .
