We run a 00 malibu escape v-drive. we are going to plumb in 2 500 lb sacs in the back, 1 in the rod locker and 1 in the front ice chest with roughly 1000lbs in the front. my thoughts are 2 jabsco reversible pumps on a through hull fitting one for the front one for the back. run the hoses to fill one bag and run over to the other bag and vent on the second bag or maybe not. if i do not vent I will have to watch the bags till they fill. any suggestions would be great we will do it this week thank you

JUST INSTALL A VENT THAT INSURES NO DAMAGE TO THE SACKS AND YOU NEVER HAVE TO WORRY ABOUT FORGETTING TO WATCH THEM.IF YOUR LIKE ME YOU TRYING TO GET OTHER STUFF TOGETHER ROPES,BINDING LUBE THE RIGHT MUSIC,JUST ONE LESS THING TO REMEMBER
