Water Shot 15 Feet Out Of The Carb

[epoxy]

hi my name is greg i have a 1988 20.7 Beretta 4 cylinder aq131d Volvo Pena with a275 Volvo out drive i put new 'points ,cap , rotor,plugs,wires, fuel pump,fuel filter , new starter,ground wire on alt, over fill breather,new battery's ,lower unit oil,new zinc's . new tank of 94 octane gasoline , new speed o pick up . i put the boat in the water started great ran great all gauges working took off.all was great plain ed off well , went around the small bay a few times then the boat died like someone tured the key off .i started to crank the motor over and a 15 or 10 foot shoot of water came shooting out of the carb i thought i was seeing things ,i then removed the engine cover completely. hit the key again and another burst of salt water shot out of the carb then the motor wouldn't do anything just clicks as this motor is antifreeze cooled and the engine temp gauge was at 120-130 degrees and it was not anti freeze for sure that shot out . could ithave something to do with the exhaust manifold .as i do not know if the riser's or mainfold have ever been changed .what do i need to do now besides pull the 4 plugs then crank motor over to clear the cyclinders maybe put some oil spray in each cyclinder and crank it over so they will not rust oil change what eles do i need to do please help..............
also the tilt works when it wants to if i bang or push or pull on the black box above the tilt motor with the relays and switch behind the engine the lite will come on the dash for the tilt and the up wont work only the down play with the box more push it up or down it starts to work again but when i need it to work it fails me i need it to work all the time please help me i thought i did the pre season work but now i do not know anything help me everyone please greg god bless thank you

If you have salt water coming out of the carb, you have a big problem. There must be salt water in the cylinders. How it got there, I'm not sure yet, but I do know that if you don't get it out within hours of it happening, You loose an engine.
Get it out of the water, pull the spark plugs and get the water out of the cylinders. Start it if you can without any water going to the engine. If only for 15 to 20 seconds at a time.
Thinking that the antifreeze side might also be compromised, drain it, pull the raw water pump impeller and get it running, and oiled up...... NOW>

Re: Water Shot 15 Feet Out Of The Carb

Have you tried to turn the engine over? If not, pull the plugs and try.
My guess, it's locked up solid.
After that long in salt water, I call them junk.
But I'm not there to see what is going on

Re: Water Shot 15 Feet Out Of The Carb

Im a little confused to. In order for it to shoot as high as your saying you not only have a volume of water high enough to fill at least 1 cylinder but also enough to fill the intake manifold. On top of that you must have all 4 intake valves stuck open. If even 1 of the intake valves shut, if that cylinder has water in, which it would because the intake is obviously filled with water, the motor will simply lock up. You can't compress water.
The best thing you can do including what Don said is also to keep the plugs out and litterly HOSE the cylinders through the plugs and HOSE down the intake manifold with WD40 or some kind of oil.
I'm going to take a small guess here and say your motor is shot. If water is truely shooting out of the intake that hard then you have some catastrophic damage in there somewhere.

Re: Water Shot 15 Feet Out Of The Carb

are you sure if was coming out of the carb and from a hose?

Re: Water Shot 15 Feet Out Of The Carb

Send some pics of this, I would love to see that problem.

Re: Water Shot 15 Feet Out Of The Carb

How can it shoot out of the carb with a flame arrestor on it?

 

[epoxy]

Re: Water Shot 15 Feet Out Of The Carb

Not to pick but I HIGHLY DOUBT it came out the carb. If nothing else your flame arrestor would not allow it. What I do suspect is a blown hose or a intake manifold with a rotted water passage.

hi thank you for all the feed back i did not have the air cleaner on the carb as this was the first run of the season and as i said i truely thought i was seeing things myself i never seen this in my life.i pulled the engine hatch so i could see the motor clearly so i hit the key and clicked and turned just a little enough to shoot water straight out of the carb and all over me then the motor wouldn't do anythink put click today i pulled the spark plugs and 3&4 cyclinders had water in them i hit the key and the new starter just smoked so i put a crestin wrench on the front pulley as i don;t have a socket that would fit any how i was able to turn the motor over many times and water poured out of 3&4 ithen after i pulled the exhust manifold off sprayed the ex haust and spark plug holes down with wd40 and the carb and then turned the engine over and over with that cresing wrench i also took off the new starter that now just smokes i did notice the belt that works the over head cam is not on the pulleys all the way like a quater off put the tenision of the belt is tight i almost give up i do not know crab about this aq131d volvo penta or this 275 outdrive any help is welcome i checked the dip stick 7times it looks brand new not a sign of water no milk looks brand new what the h... is going on please AVISE ME GOD BLESS US AND ALL ARE BOATS SINCERLY CONFUSSED . HOW CAN WATER SHOOT OUT THE CARB AND NOT BE ANY IN THE OIL CRAZY

Re: Water Shot 15 Feet Out Of The Carb

Dont dismantle that engine just yet. You may have just blown a cooling hose. Or manny

Re: Water Shot 15 Feet Out Of The Carb

Like Don said first, "You got problems."
First, water, alot of water, suddenly dumping into your motor. Second, I'd almost guarantee you that your timing belt has jumped, if you haven't sucked a valve. Because that water had to be force up thru your carb, and a cylinder on the way up with the exhaust valve closed, and intake open, seems most likely, same thing for how that water may have gotten ingested to begin with. Check your crank to cam timing marks.
Also, any chance you disconnected the battery cables while the motor was off, and hooked them up backwards? Cranking a motor backwards does all sorts of funky stuff, and you said yours is smoked.

Re: Water Shot 15 Feet Out Of The Carb

Blowing a cooling hose would not cause water to be in a cylinder. No and ifs or buts about that.

A cracked head could cause the problems you are seeing. The crack would be in between #3 and 4...also a leaking head gasket and or intake gasket as well. A rotted out exhaust manifold would also be a culprit.

It sure sounds like its time to start taking this engine apart...pull the exhaust first and inspect....then intake....then heads.

Re: Water Shot 15 Feet Out Of The Carb

belt that works the over head cam

Ok,

I'll display my ignorance ......It's an overhead cam engine?

Early four cylinder Volvos, are Volvos ^^^^^ Yup

when i pulled the exhaust manifold there was only water in #3&4 cyclinders no anti freeze period so i don't think its a crack head or casket as this motor has closed anti freeze cooling system . how do you check the timing marks excactly as i said the timing belt is a quater way off the front top pulley i know this not right is it possible this happened when the motor sucked in the water or is this the reason maybe it sucked the waterin or,,, a combination of a bad exchaust manifold with a timing belt that jumped sorry ..more confused.thank you for your help any advice is welcomed god bless...

Re: Water Shot 15 Feet Out Of The Carb

This just doesn't make any sense whatsoever now! I understand your confusion!
If your system is a CLOSED antifreeze cooling system....then how is raw water getting into the engine??????????

hi don i pulled the spark plugs and the exhuast manifold water came out of #3& 4 cyclinders only water no anti freeze check the anti freeze resivor full tried to turn the key and the brand new starter i just put on 3 days before all this just started all the starter did was smoke look like the smoke was coming off the ground wire were it goes into the starter it s self so i was able to get a cresing wrench on the crank pulley and turn the motor over 10 to15 times the first 3 to4 times water just poured out i turned and turned untill i couldnt see or hear any water i then sprayed 10wd40 into the carb spark plug holes and the exhaust ports the manifold is in poor poor condition the hose under neath just fell off and the previous owner just chaulk the hell out both ends as far as the water pump i bought a new inpellor and seal with a key way and gasket took the cover off and the inpellor looked brand new so i put the new gasket on and put the cover back as the boat on the trailer ran great and no sign off pump problem the temp gauge 120 130 so i did nt think this was the issue i do see the timing belt being 1/4 inch off the front top pulley is i don't know when thi happened before or after this any help please thank you greg

Hmm,

Well, if this is a overhead cam engine that has a belt and that belt has slipped/came off etc.......AND if theres no cracks in the head, block, manifold or riser, it may very well be a case of reversion........which would happen if the engine was turning when the camshaft became "out of time" It would only take a few revolutions....


In any case, first things first. Getting all the water out of the engine is paramount to preventing permanent damage.

Pull the risers and manifolds and post pictures here of the mating surfaces.

I would definitely check your timing belt. It is very easy and is exactly the same as the automotive Volvo B21 engine. Google that engine on the web and you will find many articles talking about timing belts on it. Fortunately, that engine is not an interference engine so your valves won't hit the cylinders if your timing belt breaks or slips.

I would change the timing belt while you are at it.
