I am a novice boat owner and have a problem... I had my 1991 boat with Mercruiser Alpha One 3.0 I/O winterized last year and de-winterized last week by the same marina. When I went to put hte boat in the water, I realized that they didn't put the drain plug in, so the engine was partially submerged for a few minutes!<br /><br />The boat will not start now. I have two batteries and each time I try and start the boat it drains the battery. I bought a new battery and it dies when I try and start it a few times. <br /><br />The boat did start on Saturday and I idled it for about 1/2 hour. When I put the boat in reverse it died immediately, then never started again.<br /><br />I know the marina will ultimately be responsbile, but am I looking at a huge problem or likely something simple? Thanks!
