When we purchased our IP 420 (2002) it had a panda genset with 260 hours. I think the longest it worked between repairs was 35 hours, average was about 13 hours. Extremely poor customer to functionally no customer service. Did a lot of research with genset repair technicians. Replaced with a Northern Lights and have been extremely happy. Has been totally reliable. Routine maintenance every 100 hours. It is nice to have something reliable when you want to charge the batteries or put the AC on at night. Only problem was sea grass clogs in the thru-hull raw water cooler. Solved this with Hinged Grocco Strainer on hull.
