If you want anyone to read that, you better retype it in lower case so it's readable.
That hurts my eyes to even look at it.

Re: Over Heating And Water In The Oil

I'll go slow so you can understand.

Please post year, model of motor and out drive.

Year meaning, what year, you can read it off the transom last 2 numbers.

Out drive, what make of out drive.

You mentioned omc.

Does it have a half moon gear, or rams.

You posted, you took out the t-stat, and it runs good.

And it still overheats when you stop? How did the engine mounted water pump vanes look like?

At what temp. does it run. With no t-stat should not even register on the temp gauge. Maybe 120.

You posted you changed out the block.

Was it a marine block?

Car block and you transfered everything over to the new block?

You use new gaskets?

You used the same manifolds?

Manifolds ok?

You posted you welded a riser.

Where did you weld it?

What side was that riser?

You posted the riser don't leak.

You posted you took out the flappers?

Are there any pieces blocking your exhaust?

Did you ever change the impeller?

Was it all in one piece?

And if it was all broke up, did you find all the pieces.

Just a few questions, i await your reply.

Re: Over Heating And Water In The Oil

New out drive impeller.

Have you ever run the boat without water going to the drive?

Even for 5 minutes?

Be truthful, we are like your priest, and doctor.

You can lie to your wife, your mother, but we got to have the truth, and nothing but the truth.

You symptoms sound like ether a blockage in the exhaust, or the impeller shot.

Any heat exchanger could be blocked.

You could raise your riser with a adapter.

Or the engine mounted water pump is shot.

Re: Over Heating And Water In The Oil

i can thruthfully say i have never ran the boat w/o water hooked to it or even turned over the motor and the impellar is brand new housing gaskets and all i even siliconed the botls before putting them back in ans as far as the exhaust being stopped up it is throwing to much water from it to be clogged up as i said i can go across the water and it runs 140 to 160 i stop the boat and boom 190 plus:confused:

Ayuh,...

It could very well be the fact that you removed the T-Stat...

The T-Stat is very Necessary to direct the flow of the water...

Re: Over Heating And Water In The Oil

Thats what i was leaning toward. Well ineed to do a compression test i have not yet done this planning on that today if i get a chance to go to napa and get a tester.Iwander if removing the flappers have any thing to do w/water in the oil.Do you really need the flappers in the boat if you never leave it in the water for a long period of time.:confused:

Re: Over Heating And Water In The Oil

Were the old exhaust manifolds used?
Is that what was welded?

All that money in the engine i would have put new manifolds on...

Re: Over Heating And Water In The Oil

I don't know how low your boat sits in the back.

But when you come to a stop on the water leave it running for 2-3 minutes water can't enter the back.

I think ether the mating surfaces are not clean and true of the manifolds, heads or the combination of the 2.

And a vacuum test is better than a compression check or do both.

Post your result.

No way with no t-stat your can run with a normal motor, 140-160 and it go to 190, no way.

You do know certain conditions with the timing off, or valve springs to tight can make you run hot.
