Once I "broke" the fan free, it worked fine for a while (but ultimately i did replace as the bearing became noisy). Got a replacement for about $30 (mine was a 3" diameter). Good luck and welcome to the forum--great folks here always willing to lend a hand and sometimes a little humor or sarcasm. Oh yeah. . .pix are kind of a big deal here too!
When a bilge pump gets hung up, its usually due to corrosion and time to replace so it works when you need it. Sometimes they will suck in some debris and plug up. Put a garden hose against the pump outlet and give it a little backflush. Sometimes that is all it takes.
