Hey guys, need your input. Last summer purchased an `03 Chaparral 243 Sunesta, Volvo 5.0 gxib engine with approximately 400 hours on it. When I put her away for the winter, she was running strong, no problems. I was putting together a spring cleaning list for the boat and wonder if I should consider replacing the distributor cap, rotor and plug wires as part of preventative maintence or let it go for another year or so.
