as far as the burning out the impellers I have not had any issues, you can hear the sound the moment the bags are empty. As far as filling i have over filled but never popped a hose off. I didnt take any pictures of the thru hulls. I followed someone elses mod off the the forum. I mount exactly where he did. They are on the side where the the existing thru hull is. I believe one in front and one in the back.
this is what i followed!
