I have power pole blades 8 ft. The port side gets stuck in the down position when fully deployed. It does this in Open Water. It will eventually come up after 10 seconds to two minutes of holding down the switch it does this no matter which remote I am using. The pump runs is just seems like it's either bypassing or something stuck in the lines. I have checked all the lines and nothing is pinched. I have seen a couple of threads on this but never really seen an answer. Outside of installing some sort of rubber block. Any ideas?
