What can happen if one doesn't flush a motor after it was used in saltwater? I've always heard to flush the motor. But honestly, I just realized that I never flushed my motor last time I took it out about a month ago. Is it doomed? My buddy also hasn't flushed his motor from last use on Sunday morning. Is it really a big deal? What about the people that leave their boats docked in saltwater, do they flush their motors? EDIT: I just realized that this should be moved to the Outboard Maintenance section. I'm sorry for my mistake.
