5.0 Volvo Penta Motor will crank and immediately shut off
2005 Chaparral SSi 236 with 5.0 Volvo Penta. I've had no issues with the boat cranking until last week. Crunk right up and went 3 minutes down the lake and turned it off for about 5 min. Tried to start it again and it turns over and cranks up for just a split second. Charged battery to make sure it's getting full power. Had someone check the fuel pump/filter and it all looked good. Any suggestions? I had heard inboards were nothing but trouble and I'm hoping this will be something simple.
