Can someone PLEASE expalin to me how to get my prop off of my engine??? It is a 70hp force.........I bought it from an individual used, the engine is a 75hp force, but the lower unit is from a 70hp force due to him nailing a stump with the original one. Anyways, i cant figure out how to take the prop off??? How do you keep it from spinning when taking it off, also how do you take the nut off connecting to it. it has some kind of special washer of some sort that appears to be holding it on??/ Any advice appriciated!!!
