So my father in laws 2004ish 50 hp 4 stroke Yamaha got completely submerged in tidal water. Went through one tide cycle. Was NOT attempted to start after.
No owners manual.
So what do we need to do?
Drain carbs, change all oils, pull plugs & spray cylinders with WD-40, ...???
Anyone have any idea what the recommended oils are for crankcase & lower end?
Also, battery was submerged. Do I need to drain it & replace eloctrolyte?
