I have a 1995 Bayliner with a 120hp Force 2 stroke engine. I took it out two weeks ago with a full tank of oil/gas mix. I mixed a little more 30:1 mix than my usual 50:1 but it ran fine the day I filled it up. Now two weeks after sitting out in the hot sun it won't start. I thought it was the battery so I got a new one. After a few minutes of cranking the key the new batter seems to run out of juice. It just won't turn over. Any suggestions?<br /><br />Thank<br />Rommel
