Couldn’t help but laugh reading that?. Glad you found it?

Your part number is 60E-14610-00-94. Check part through YamahaSportsPlaza.com for example. I would try filling crevasses with JB-Weld if you cannot find part at your price.

I just ordered manifolds off of a fresh water 2005 fx ho has 60E stamped on it looks the same. I could jb weld but to be honest I never wanna pull the motor again lol I will also keep a eye on oil on second engine and check the manifolds on that one at the end of season I pressurized it and it passed oil looks good for now.

Hang on to old manifolds. At some point, you may find them of some value. Hope all goes well.

Yea will keep them for sure wonder if someone who welds aluminum could fix em.

I have a corrosion canal in the cylinder head patched with jb weld. It has three hours at 7k with no issues so far. Milky oil repair

Well this is a slap in the face new fresh water manifolds came installed and guess what I STILL HAVE A LEAK!!! air blows out the cylinders i saw no damage when re installing. Anyone have any suggestions i am really at a loss here dont know what to do i thought for sure this would fix it as old manifolds had chips missing coolant passages on head for manifolds look fine.

What do you mean by "air blows out of cylinders?"

What do you mean by "air blows out of cylinders?"

I hook compressed air into the water inlet and when the 1 line is on the big rubber boot Air comes out of whatever cylinders exhaust valve is open. The other engine does not do this so from what i can tell thats how water gets in my oil

 

[jws123]

Actually you know what I am going to go take some videos of whats going on i am sure it will help you guys help me Lol

 

[WREKS]

How about reversing the process. Push compressed air into the exhausts and see if it comes out a cooling passage.

 

[jws123]

Il try that I also just thought of a idea maybe i can use my EVAP smoker with air from a car to see where smoke comes out of to find leak.

My friend had water is his oil this was the problem

Exactly i replaced the manifolds due to this lol its still doing it.

 

[jws123]

Ok after getting pissed at it letting it sit for few weeks I just tore into it now exhaust is off I pressurized the head on the engine and it checks out so far so it tells me its still exhaust related going to try to figure out how to test exhaust while its off I needa get this baby on the water ahahaha.

@Brad_Ct has replaced some seals in the exhaust system that were problematic. Others have found small holes when closely inspecting the exhaust manifolds.

Welp all back together same issue still looked at and tested the exhaust 100x times cant be a exhaust issue I am at a loss i put air in system air comers out 1 cylinder for example depending upon position engine it can come out each cylinder only 1 at a time tho I assume i have a crack in the head or block somewhere just odd to me no compression loss. ALSO ON A SIDE NOTE the pressure control valve that sits on the block is it suppose to be open or closed? rn nothing flows past it wondering if i have backpressure issue but not sure how it works.

 

[WREKS]

If I remember right, the Schroeder valve can be removed from the plug end of a compression tester. Then an air supply can be teed in between the tester and the pressure gauge. That way the cylinders can be pressurized to check for leaks.

I am at a loss tearing engine down pulling head off it has to be a issue with a water jacket blowing air into the crankcase or something since i have no loss of compression I have been trying to just fine a replacement engine out of a ski or something but no luck so far,
