Mine is a 2008 1802 WA...for the first time I'm keeping the boat in the water this year. The 1802 does not have scuppers so when it rains all of the water goes down into the bilge. My question is how long should I expect the battery to last with the bilge pump pumping water out? I find myself running up to the lake checking on the boat after heavy rains. I have a feeling I'm being overly paranoid. Any thoughts? I keep the battery turned off when not on the boat to preserve all battery power. The bilge is wired directly to the battery. Just don't want to show up and find the boat at the bottom of the lake.
