I have a 18.5' Alumacraft Navigator tiller boat and I'm concerned I may have a leak(s) in the hull since the pump blew out water for about 5 minutes when done fishing. Curious how I can get the bottom checked with such a big boat and no "lift" to pick it up? Limited to repair shop? I'm not even sure there are leaks with all the rain last week but I've fished in heavy rain before without this much water being pumped out. Any suggestions in the Madison area if I need to have it checked? Thanks !!
