Something no one has mentioned. (Do everything these guys have said as well to ensure the engines wont be ruined. Esp remove the spark plugs and leave them out until the motor spins). If you had a blow out it is likely the clean out hatch switches are no longer adjusted correctly.. removed spark plugs and leave them out, open clean out hatch and have someone physically hold down the kill switch and try turning the motor with the key... if it spins then it's the kill switches under the clean out hatch, if not... maybe starter? If you can reach the starter you may be Be able to use jumper cables to hit the starter directly with juice. Just enough to see if it will spin or not. That may help you narrow down the issue.
Do I have to remove all spark plugs ?

you also could have blown fuses,


did you open the engine hatch when it was flooding? how high was the water in the engine compartment? over the engine? half way up?

At this point you need a multimeter to check the electrical because it could be the hatch safety switches, fuses, starter and if your not able to do that then you need to get it to a mechanic,

Yes.... if there is water on tip of the piston and u try to start it you can bend a connecting rod and run you engine. With the spark plug out if there us water on top of the piston it will shoot out the spark plug hole.

I checked all the fused with the screw off cap in the engine hatch both sides, as well as the two near the battery

Yes i did, it was about 3/4 on an angle since the back was so heavy. Where would i connect my multimeter too, i can’t even find the starter.

Can you try cranking as is with the spark plugs off?? You may not need to find the starter if that works.

And... Stop trying to start it and possibly causing more damage. Pull the spark plugs first and foremost.

Don't look down the holes while trying to start.. Unless you want a face full of water. Place a towel over the engine.

Make sure to disconnect the lanyard before cranking without plugs.

I am honestly betting on a stuck started or a locked up pump. If the engine was full of water you would see it in the oil and if the engine hatched you would probably see it at the end of the spark plugs, so either bad electrical issues caused by the water or stuck pump etc I would get some spray silicon and spray every electrical plug and connector you can find, Open the ones you can spray the silicon in and then close it. soak everything with it.

Jeff, I'm totally hoping you are right, but the easiest way to know for sure that there is no water in the cylinders is to crank with the plugs off first. No harm in checking.

No you cannot unless you have shutoff valves. Did you try turning the engines over with no spark plugs in? We need you to calm down and work with us. We will help you through this.
