Ended up being the clutch dog and reverse gear were wore out... 550 for parts...I almost ended up getting a whole new lower unit, but a buddy was able to find the parts...The shop said they discontinued the parts Yada Yada Yada, but some shop in Hackensack was able to find them I guess...just want the dang boat back ha...
OK, to go back to original question, how much current do the 12 volt pumps used in those sort of systems use? I can go look up the information and figure it out, but I hoped someone here already knew the answer.
My family has LIfe 360 on our phones. It allows you to know exactly where that phone is at all times. My teenage kids were not to hip on the idea until my wife explained that you either have the app or you don't have a phone. It already saved a phone. My son dropped his phone in the middle of a bean field last summer. We were able to use the app to drive a wheeler to within 10ft. Well worth it.
My personal opinion on the backup pumps is that they are a stop gap to buy you enough time to minimize the amount of water that backs up during a torrential storm while you get your primary pumps on a generator.
Obviously the biggest factor is to figure out how much water can enter the drainage system during the heaviest downpours and that can help you decide what gpm you need to stay ahead of the water. If you get a bigger backup pump then you will burn through a battery faster.
If you don't get a lot of water in the system ever and if the sump pump only runs periodically during even heavy rains and wet weather then you can get more run time from a smaller system.
There really isn't a way to say exactly what you need to be 100%safe unless you know exactly what flows you have.
Sunday, pulled a group of 3 toms from about 500 yds across private into the public only to hang up at 60 yds. We worked them for 2 hrs and they never got in front of the blind. They finally got closer, but instead of going in front of the blind, they got behind the blind at about 5 yards inside the woodline and could hear them stepping on twigs. Man what a rush. Sadly, they walked back onto private and out of our lives LOL. Kinda wish I was hunting with a shotgun!
3 or 4 gobblers were rattling off behind us in the woods in the morning and shut up by 7. The 3 that we got to come in from private were to the other side and they didn't gobble til they were close enough to see/hear our setup. Those two hours were between 8 and 10. Will try again.
