serial number od198941 I ran my boat other day without oil .I ran was across a small lake and back maybe a mile or so and didn't think anything about the oil until next day in 20 yrs that's a first. I hand mix my oil so question is it didn't seize up so should I pull the plugs and put some oil in them before I start it up until my premix oil gets to it .and that tank was bone dry to so wasn't no oil in it .
