Water In Cylinders

Just swapped 787 motor out of my 96 GTX. Bought a used motor, hooked everything up today and turned the water on and tried to fire the motor. The motor would not turn over. I pulled the plugs and water poured out of the front cylinder and the rear cylinder has water in it also. Also the whole exhaust filled up with water.

Not sure where to start on what is wrong ? Also what do I do with the motor now that it has water all through it ? I turned it over with the plugs out to get the majority of the water out.
 
You might have just screwed the pooch. Here's the process.

Engine on. Water on. Water off. Engine off.

If you don't you will flood the engine. Get the engine running immediately otherwise you will have a boat anchor as it will rust
 
Well the problem is, as you probably already know is you turned the water on before you started the motor. The proper procedure is start the motor, turn on the water, turn off the water stop the motor. I guess just keep turn over the motor with the starter and get all the water out that you can. If it's showing any signs of life try to get the motor running to burn off the water, maybe try to spray some fogging oil in the cylinders to try to displace the water.

I really don't know what else to tell you, maybe someone else has an idea.

Used engine

A rebuilt engine with a 1-2 year no fault warranty is like $800...

I hope you didn't pay more for a used engine.

The key now is get that engine running. NOW. not later. Not tomorrow. Not next week. NOW.

internals are bare metal and rust in hours.

Get it running and go ride it for at least a 1/2 hr.
 
Just to drive this home a bit, you MUST get the engine running and up to temperature to clear the residual water that is hiding in the engine. If you don't, you will be needing ANOTHER engine. The issue is, the engine is not designed to run on the hose for more than 2 minutes which isn't enough time to get the engine hot enough to get rid of the water. Once you get it started, you really need to get to the ramp and back it down and let it run. Even if it is midnight,,,,
 
How long was the water running? Just want to be sure it was flooded from the hose being turned on too long & not something else. I also hope this engine is not just sitting, it needs to be out on the water all weekend IMO :(
 
Since reading this I was thinking about what a guy could do if the engine isn't ready for run time.
If it was me I would try to fill the case with something to submerge the bearings & displace the moisture.

I just made a post in another thread about this. Is there anything out there that is hydroscopic & wouldn't be harmful otherwise? I would much rather fugure out how to clear out an engine full of diesel oil than have roasted bearings in the next dozen hours of run time.

The bad part is, water sinks to the bottom in every type of oil I know of.

What you say is pretty much what i'd do and have done in the past...

I have never filled the motor with water, but I have been pondering what I would do. The closest ramp is about 40 minutes away and is not open at night. Since the bearings are not on the very bottom of the case, the diesel may be good enough if you get most of the water out. WD40 was developed as a water-disperser so it may be the best. But I do not know. I would probably crank it until I got most everything out with the plugs out. Fill it with a ton of WD40 and crank it again. Also disconnect the pulse line as that seems to be a good lower end vent spot. Then get it started if possible. Pull back the carbon seal and run for a few minutes. Then fill it with diesel until I could get it to the lake. If I lived in the country, I would drop it in a kiddie pool, but I am in suburbia so that just would not fly at midnight.

There are also water soluble oils that they use in machine shops, but am not sure if that would protect from corrosion or not.
 
The original poster has not been back in this thread. I hope he was working on getting that water out and actually starting and running the engine last night. I know that we all wish that he'd done a little research on this forum to find the correct garden hose water procedure before he tried to start the engine.
 
I wish I would have done the research too, I've pulled the motor and even the counterbalance shaft if full of water. Looks like next winters project, guess it's just the boat for me this year.

Don't give up yet!!! Pull the jet pump and driveshaft so you can run it for 30 min on hose. That shoul dry out the bearings.

Tough way to learn a lesson.

When I bought mine new in 96 I sunk it the second day because I didnt put the plugs. Last time that ever happened.
 
I dropped my back end into a great big paddling pool about 3 ft deep 12 ft diameter (£30 from B&Q). Was able to run my ski for a long time (60 mins plus). Hope you get it sorted.

Hey rhombus... 60 min runnin in kiddie pool??? Really??? Was the water warm after you was done??? Kool... Sounds like idle is a tad too low...

Oh the water temp wasn't much difference as I had the hose running to refill the spillage, when I was running for a while. I got quite wet though :)

I'll bet your neighbors just love you. lol
 
Ah yes! He can't complain though as he races bikes and has on occasion had to do a similar thing! A bit of luck there:)
