Yes there is a difference, mostly in quality, solas is is prolly one of the best SS props you can get that is just a all around good prop, stong and durable, Michigan wheel props are not as strong or durable. Lots of good prop manufactuers out there. Just have to do a little homework, to figure out which is best for you application and your pocketbook. I fish Lake Conway 90% of my fishing time and I am running a OMC prop on my 150 johnson, i have found that the maker of the outboard has the best props for thier motors at about the same price. I am running a 24pitch raker prop made by OMC for Omc/bombardier outboards, it will chew those stumps and spit them out. And it still looks new and its been used on lake conway since 2002.
