Decided not to fish and just take the wife and kid out for a day of tubing and knee boarding. So i pulled out the extra battery thinking no leaks so no need for extra battery. Dropped the boat in, ran for about 10 minute to the ski zone. Shut the motor down and notices a very very strange "roll" as the boat came to a stop. boat seemed to be sitting a little lower. move the fuel tank out of the way and i have 8 iches of water the entire lenth of the boat. a 17' bait tank!!
