salt in cylinders? on omc v8

[jamesjean03]

hi my neihbor gave me a bayliner trophy with an omc v8 in it i tried to start it and just click click she had the entire engine replaced NEW in the spring.she got divorced Never used the boat but once and left it in the water all season, Now the problem when i pulles the plugs,which by the way were all super loose 3 plugs where covered in a white goop like salt! there is Absolutly NO TRACE of water in the oil so i assume moister got in from the loose plugs. So the engine wont turn i tried a breaker bar on the balacer! so i assume the salt or wahtever it is is actinglike a glue in those cyliders! when i take a little of that salt looking substance between my fingers it just melts away, so at this point could i try to flush out those cylinders with hot water and then blow em dry with compressed air and immedietly fillem with marvelmystery oil or would that do even more damage? i mean the crank case oil is pure gold and the rockers and valve covers are in perfect condition! Any help would be great! thanks james babylon ny

Put some penetrating oil in the cylinders, let 'em sit and then break it loose. I suspect you have bad risers or manifolds, which leaked some water into the motor. Are the mannys and risers new? You may end up overhauling the motor, by honing the cylinders and putting in new rings..

Have you removed all the plugs then tried to turn it over? There may be one or more cylinders completely full of water. It will feel like its seized up with the water in there. With all the plugs out, you may be able to spin it over and pump out the water, then add some mmo and crank some more.

You can do anything you want to free up that engine, but if there is truly saltwater in a cylinder and it's been there more than a day, that motor is Junk.

Re: salt in cylinders? on omc v8

First off are you sure the battery is charged fully, and click click could be simply a loose or corroded connection, with the plugs in that motor will be tough to turn by hand especially if it's been sitting. Pull plugs and put penetrating oil in clinders, do not even try filling them with water and blowing it out with compressed air thats crazy, you mignt try inserting a small clear straw-like hose and see if you can suck any water out each cylinder, if you do get any water than your done pull the heads.

Re: salt in cylinders? on omc v8

thanks, i have althe plugs out and nothing i filled the cylenders with oiland illcheck it tommorow

Re: salt in cylinders? on omc v8

I would still take a small clear hose (fish aquarium) and insert it down into each cylinder one at a time and just slightly draw on it with my mouth till i see what starts comming up the tube, water is heavier than oil and if there is water sitting in the cylinder the oil you put in there is just sitting on top the water and doing absolutely nothing.

I once came across an old boat with a 350 OMC that had been sitting for years. The motor was locked up. We put some oil into the cylinders & kept trying to crank it over while helping it with a breaker bar. We finally got it to fire up & that was the best running engine there ever was. The boat was used for 2 years until it was sold. We may have got lucky, but it worked!

Hopefully you can get this boat running as well.

well thats the encouragement ineed thanks!

If you find no water in the cyl. breaking it loose shouldn't be too hard, one thing is be careful you don't snap the crank bolt or pull the threads, if you have enough room try screwing two long 3/8" bolts into the balancer, that way you can use a piece of pipe between them and lever the crank in both directions. I'm refering to the holes in the balancer that are there for use of a harmonic balancer puller.

Re: salt in cylinders? on omc v8

thats a great idea! I will try that also thankyou so much and i will keep you posted James

But I can guarantee you that motor wasn't full of saltwater when you found it.
If this engine has saltwater in it, it is junk.

Take the drive off first might be stopping the motor from turning.

My post was not complete, i should have first posted that pb blaster is the stuff to shoot in the cylinders.

Pull the valve covers, what do you see?

Rust, shoot the push rods shoot everything under the valve covers with pb blaster.

But if the spark plugs were in but not tight water, saltwater that is didn't get in there that way.

I would not try to turn it with the starter your just gonna burn it out.

If after shooting the cylinders letting it sit, and shooting it again you can't get it to turn than, it's time to pull the motor.

Drain the oil turn it over and pull the pan than you will see whats what.

Last post, i posted pull the drive it should be the first thing you do.

What year is this boat?

What sorta drive?

Now one last thing cause you must be getting bored with me, if truly saltwater sat in that motor more than week it's a anchor.

More likely 2-3 days if saltwater sat in there no saving the motor.

Sorry.

mmmmm,no update? Wonder if he got it to turn...

Re: salt in cylinders? on omc v8

Maybe other life commitments have taken first stage, and the boat was put on the back burner.

I myself just got to drain the power steering pump on the wifes car.

After tightening the new belts no more screeching like a bancee.
