I was told by sbt and some other compines that it would be better if I removed it. They say they seen plenty of engines go bad due to the system failing. I prefer it but I'm new to this boat. Just thought I would really find out by the people who drive them. What lines are you talking about replacing after oil filter. Just the plan lines that are there? What else should I watch and and service besides plugs n filters n carbs?....thanks for the help...
