Help with TrackerTarga fuse box?

Question

I can hear "hum" when I flip the switch for aerators, but it doesn't fill. I am thinking fuse, but I can't find a diagram of my fuse box. My manual says to clean the impellar, where is it? I have a 2003 Tracker Targa 18 ft, walk thru with windshield. Any help appreciated, and thanks to all you GREAT folks who have helped me in the past. LOVE this site!!!!

Answer 1

Make sure you have opened the Thur hull to allow the water in>The impeller is where the hum is>Contact tracker for a fuse panel diagram>

Answer 2

hear the hum?  tells you the motor is spinning, therefore the fuse must be ok.

here's what happens.

being a gravity-fed pump, when you get a bubble in the intake, it can't draw water through.  It's called "air lock".

the solution is to crank the engine, throw it in reverse & rev it, just for a second or two.  gets the water flowing.

seems like it hardly ever happens with a brand new pump, so maybe the impeller gets worn down?   I dunno.

Best check it visually first, just to make sure nothing's caught in it.
