Default Could be hydrolocked ?

I just posted another thread about my starter problem but just reading i think and i hope im wrong on this but maybe my motor is hydroloked, I was at the lake friday and i notice the boat wasnt the same , i saw no water out of the headers and the temp was like 230 or so, i slowed down and saw oil pressure like 15 or 20 when its like 50 or above usually. I shut it off and opened the hatch and alot of steam in there, my blower works but the tube that is supposed to go over the tramson was unhooked so i think thats why it was that bad, anyways, my oil filter was really hot , so here i am really scared about my wife telling me i told you so and getting pissed at me when i get home. I tried to start the engine to get home but it would turn with no problem and started a couple of times, run really bad like running out of gas and then shut off, kept trying but wouldnt start, motor still turning till the started just started spinning meaning the vendex wasnt coming out to engage,so i got towed back and that was it. I took the started and replaced it with another one, it turned the motore ok for a couple of times, never fired though but it started making noises like it needed shims, oh and when looking around the boat i pulled the plug wire that goes to the coil and it was broken so maybe thats why it woulnt start, dunno yet, but am i in big trouble or its just my starter? if i hydrolocked the motor it would of happened at the lake right? i need some help guys.
Thanks

If you hydrolock a motor it won't turn over let alone start.
Sounds like you ran it out of water.
replace the water pump impellar
check the spark plugs - you may have burnt the electrodes off.
replace all the plug wires.
but first do a compression test.
if it passes the comp test then also change the oil.
GOOD LUCK

To hydro lock a motor you would of had to fill a cylinder with enough water to prevent the piston from reaching top dead center. Water is not compressible. If the mas of water is greater than the volume in the cylinder at top dead center , when the piston approaches T.D.S. it will hit a wall of water. since water is not compressible then something must give. generally you bed a rod.

Was there any way you could of in-jested water into a cylinder??

Take off you oil filter and cut it open. look in the pleats for any coper or brass colored metal. If you find any, I feel for you. Also check to see if the oil has a metallic glitter to it.

If you lost oil pressure ten that is a very bad thing.

I wouldn't try and start the engine until you check the oil and filter for any metal.

thanks for the replies guys, i dont think i injested water into the cilinder what i think happend is that i must of picked up something in the lake while running like a bag maybe, because when i started up for those few seconds, plenty of water was coming out of the headers which tells me whateve it was fell off when i was still. If i take the spark plugs out and no water comes out then it should be ok right? is that the test on hydrolocking the engine?

If the motor was hydro locked it wouldnt even turn over once.

once the motor crancks over a few times you would of evacuated the cylenders of any water .

It still would not be a bad idea to check your plugs. They should all look about the same.

im kinda feeling a little better now, i tell you this oso people are the best, the best thing i did is join this site, alot of people with alot of knowledge, and everyone is always helping one another. And we all know as boat owners that 'trouble free' in a boat doesnt go together.

The oil pressure may have been low because it was soo hot.
If you are still running the stock plug wires change them for a set of Taylor spiralpro.

Dude Sorry to say but been there done that.

I blew 3 engines in one year.

you learn very fast how to trouble shoot what happened.

the key is to be sure not to let it happen again.

If it wasn't for OSO I would of been lost.

Good luck

Paul
