I have a cheap pump I use to raise water from the [Censored]. I was unaware at the time but this [Censored] is part of a creek system and every few years they open the flood gates and it fills kilometres of creeks and dams. Anyway the water raised the level up about 6ft and left my pump fully submerged. All I did was unbolt all the bolt ons drown everything in INOX then let it all dry out. I put plenty down the plug hole and turned it over. After a few days of drying out I filled up the oil and fuel and it started second pull. I then ran it for a good hour to make sure it was plenty hot enough and dry out and moisture and change the oil again. Hasn't given a lick of trouble since. If you want the mower you could have a crack at it with nothing to lose. If it drips its lunch you can still use it as an organ donor.
