Not at the boat now. I do know it's Onan Ensign 6500 It's on a 1991 boat. I'll have to get the serial this weekend. Was there today and ran the genny for a while- it ran fine. But when going to start it back up after running it for a while- it didn't want to start. It had to sit for about 5 min before it would start up again. The mechanic told the broker " those have circuit boards and they are designed not to start up right away after running"." Let it sit for 10 min and it will start up."
That doesn't sound right to me
