Had the motor out for the first time, it was running good ( sounded, started and idled) it would not hit higher rpm’s .. only 8mph.new plugs and there all getting spark.. also when coming in to the dock, put in neutral than back into gear.. it barely moves now and motor revs like it’s in neutral still. I manually pushed the shifter on the motor all the way still same thing.. when In gear it clicks in F with ease, but won’t spin in R. When In F gear the prop won’t turn counter clockwise but clicks when turning clockwise
