The moment it happened.

5 gallons of Diesel was put into my gas tank which probably had 3 gallons of gas. Didn’t know it happened until engined died. What now? I have a boat mechanic friend and also have done some work myself. Hoping to be able to handle this between us. Drain everything, change filter and plugs, fill back up with gas and prey?
