Re: 3 blade troller prop-Worth it or no?
I swapped over to 3 blade TM props and couldn't be happier. I'm not sure if I picked up any performance or not as the old prop was pretty banged up, but I haven't had any issues with weeds, and the river I fish in is filled with nasty little stringer weeds that love to wrap around a TM. The 3 blade seems to hack them up nicely. I even put a MG 3 blade prop on my MK trolling motor. It took a bit of filling on the back edge of the prop (chucked it up in the drill press, watch your digits
) but it fits perfect now.
MG has 3 different 3 blade props; plastic, glass filled plastic, then aluminum. My MG 70# bow mount has a glass filled stock and I put an aluminum on the 70# MK transom mount. The plastic props have more deflection and can make weird noises at WOT when pitching around in the waves, where the aluminum prop doesn't make these type of noises,,, much. MG suggests different # motors for the different prop materials and the aluminum prop is actually designed for a higher thrust motor than I have it on. From comparing the props, there is less pitch in the plastic prop, more in the glass filled and most in the aluminum, the aluminum also has the least diameter, slight as it is. (I'm guessing you could overload the TM if using the wrong pitch prop on a small motor.) I'm not sure how much speed you would pick up from running the aluminum prop, but my little 14' jon boat hauls butt with the 70# TM WOT with the 3 blade aluminum....
