Hi I have a 2007 Monterey 220ex with a Volvo Penta 5-7 Gi-G engine. The last two time I have had my boat out, it's at idle in gear engine dies and cranks but will not start. I keep trying to get it started, after about one hour it starts. I load it and go home .It sucks this boat only has 50 hrs on it. Can anyone help me with this problem. THANKS
