Does the engine turn over? You wanna be sure it's not rusted up solid. Spray some penetrating oil or Marvel Mystery into each spark plug hole and rotate the crank over to spread it around or let it soak if she's locked up.

engine turns over, no problem.I do have the plugs out and looked inside the cylinders, don't see any rust

Any sign of water in one or more cylinders? If three pistons have carbon on top and one is clean maybe water is entering that one and steam cleaning the piston top. You could put the manifold back on and run it (after an oil change) and see if oil (oil/water) volume increases in crankcase. On Mercruisers diagnostic chart for water intrusion I think the first step is to determine if water is in crankcase only or crankcase and combustion chamber. You would answer this by running it as well.

Wonder if i can reuse that old manifold gasket, and put it back together, like you said
See if it will run
Maybe i will try that saturday morning

you can use that gasket just to see if it will run. It's only sealing air.

I wonder if when it started skipping if it was the first run of the season or middle of season. If it was not the first run it may not have froze.

Yea, start it up and see what happens.

I doubt bad bellows would cause water to get in engine. If it was the gimbal or shift below that would get water in boat but not engine. If it were the exhaust below....well....we all know you don't even need that one at all.

Maybe it simply overheated and blew a head gasket.

I would at least use a new manifold gasket because it's a combination intake/exhaust seal, I don't think they're very expensive. Take compression readings of the cylinders. I had a friend with a 3.0 that had no compression on the #4 cylinder and was getting water in the oil. We pulled the head and it turned out to just be a bad head gasket. He had the head reconditioned and we put it back together with a new head gasket and changed the oil and it ran fine.

If bad bellows /submerged while running water can get sucked in the rear main if water is deep enough I think. Should use a new gasket.....attached.......Bellows....first photo is Gimble housing(part that fills hole in transom.....second photo is bell housing with bellows still attached (end of bellows not attached goes on gimble housing) maybe can see flanges in photo? Third photo basically how they look assembled (no gimble ring) (steering) in photo.

couple cracked intakes......Note that these are both from v6 GMs

would love to use a new gasket, however too late to order one now. I want to try to see if I can get it to run this weekend

I will do a compression test also, and I can do a cylinder leak down test also if I need to

pray that it is just a head gasket. I have some go bad on auto engines, and had windys frosty in the engine oil

thanks for the input and pics, will look at the bellows, while I am in the engine compartment, I did look last night with a high powered flashlight, and saw no holes in the bellows, but you never know
thanks

Wow! these are from freezing?
hope my engine block did not do that internally

Retro Performance · « **Reply #51 on:** February 07, 2014, 06:33:51 AM »

Yes freeze damage.....

Have you looked under the distributor cap? Is it green under there?

I really havent had s chance to do a whole lot to the boat yet, just brought her home last Saturday. It rained Sunday, and i work a full time job, dont get home until after 6:00 pm, by that time it starts getting dark, and its been raining, snowing, ect here

So i plan on doing as many things i can tomorrow, one will be removing that dizzy cap among other things
I am looking forward to working on it

No i have not, probably has a cracked block lol

I am broke, for now..,
Thanks for the heads up on that setup

buckz6319 · « **Reply #56 on:** February 08, 2014, 04:35:26 PM »

update my test today
I just tried to pressure test the block, and i used about 15 psi, the block built pressure quick then....
I heard a "Pop! " then gurgling,
Sounds like i broke something, or blew out something,and lost air pressure

so...I went from an air test to a water pressure test...

I did a water test on the engine block, and have water pouring out below the bell housing, and below the starter, on the rear of the engine block
But not in the engine oil pan( i have the oil pan drain plug removed), it is dry, no water coming out there

So did i blow out a hose, or is it a busted block at the rear

Retro Performance · « **Reply #57 on:** February 08, 2014, 04:48:13 PM »

There is a "frost" plug on the rear of the block I think..........you would need to remove the flywheel to see it I think..........Where were you putting the 15 psi in? How did you block all possible escape points for the air?

Is the motor out of the boat or still in?

still in the boat. I think I now need to remove it, didn't want to, but have no choice
