I bought the Mk-GS-P1 for my Minn Kota Fortrex 80 trolling motor. Awesome product...installed it as per the instructions, went to the Pomomac river for a two day tourney and never had to clean grass off by hand one time. Bolts on the skeg so you never have to worry about something knocking it off. It saves your batteries due to the prop not being bogged down by weeds wrapped around it. You hardly know it's there unless you are looking for it.
Oh and they threw in a buff with my purchase...can't beat that!
