I have a 1999 Rinker 270 boat it has a 5.7 in it. The problem I am having is the motor quits on its own... like someone has turned the key off. I can be driving for an hour and it just quits dead... no miss or anything... starts right back up and might run for another 10 min. and do the same thing all over again. I am told it is electrical but what?:confused:
