We moved the generator to the front yard since the back of the property slopes towards the river.
Still went underwater.
Is it a total loss or can I drain the crankcase, clean the bowl on the carbs and get it going?

We had one go under during Katrina and we brought it to a small engine repair shop (some dude's garage basically) and he flushed it out and got it working again.

It crapped out a couple years later though.

Would suggest you drain all fuel and oil. Open up electricals and spray with a product like LPS that displaces water. Dry our or replace air filter. Give the starter a couple of pulls with the spark plug removed. Dry plug off and replace. Put in fresh gas and oil and dry air filter. You should be good to go.

As long as you drain and flush every fluid from the motor it should run again. Odds are the lifespan has been drastically reduced, but if you're in need of power right now and have the fluids available....

Best of luck to you.

Edit...Follow tonydtigr's post. It's not that complicated, but if you don't have much mechanical experience I suppose it would be. Look on youtube for more explanations....

(Water Displacement - Product 40 also works for displasing water but not as good as LPS, just more prevelant.

You should be able to dry it out. remove the oil, replace the oil, turn it over with out the sparkplugs. then drain that oil and check for any substance that looks like chocolate milk. This would show signs of water still in crankcase. If the oil is clear, then put it back in and you are good to go as far as engine and lubrication and cooling.

Drain the oil and gas, pull the spark plug, pull the starter to pump out the cylinder, hose the inside with WD40 and pull the starter to help it flush out the worst of the moisture. Hose down any electrical parts with WD40 and wipe them off too. Refill the crankcase with cheap oil that meets spec, refill with fresh gas and a healthy dose of HEET or Seafoam, purge the carburetor, then get that engine cranked asap. Run until good and warmed up then drain the oil and refill with whatever oil you normally use then run again under heavy load for an hour or two. Time is your enemy now.

Drain oil,gas,takr plug out and pull rope and evacuate the cylinder. Put in new oil,gas, put plug back in.Take air filter out and squeeze out. Find starting fluid or carb cleaner and spray into carb opening. Set to choke. Pull and get running. If need be keep spraying in short bursts to keep motor running until it will run on its own fuel.

Good luck and I will be monitoring this thread should you or anyone else have any more questions.

Freshwater is certainly the best case scenario.

Flood all the electrical components with a water displacing lubricant (wd40, lps, etc). Follow the above posts for the engine.

Still a chance there is water in a "sealed" component like a CDI box or a capacitor/diode that may ultimately make a premature failure point. But if you're not running life support equipment I would take that chance.

Hope this helps.

IN addition to everything others have suggested I will add don't be afraid to use clean water to flush out dirt and mud us needed. I have a lot of experience restoring industrial and medical equipment from flooding. Clean water is not a problem, it will eventually dry and out with no damage, It is the dirt that gets into connections and between components that kills electronics.

This is the way I do it. What I tell people is that it is a good time to replace consumables (plug and filter)

Had a generator go under in Texas on a project. Paid like $75 a local shop who basically took it apart, cleaned it, put it back together, and gave it a 10 year warranty. That son of a bitch ran like a champion.

That's awesome! The longer it sits under, obviously the worse it will be.

Again, I wish the best to anyone caught in this horrible crisis.

Drain the crankcase and remove the spark plug. Roll it over so any water in the cylinder drains out. Spray some oil into the cylinder to prevent rusting. remove the bowl from underneath the carb and spray it all out with carb cleanser. I would also empty the gas tank and replace with clean fuel. Put oil back in the crankcase and fire it up. It would work if it is completely dried out and with fresh gas and oil. It will smoke for a moment because of the oil in the cylinder.
