I had this converstaion with my brother in law and he thinks it might be that the motor is running rich for the first couple of minutes and that the particles are products of the incomplete compustion. That could be the case, I guess since I dont think the automatic choke flapper is working...

Hi! I just did a full rebuild of my 3.0LX this summer due to the motor ingesting water at the exhaust elbow last year. I had that elbow re-faced and aslo added some hi-temp sealant to it when I put it back together. The motor now runs like a top, but when I start it up after it sits for a...

I just went through this with my 3.0. It was seized at beginning of season. A couple of things. Look at oil to see if it is milky. If so it has ingested water, likely through the exhaust elbow. Also make sure ur connection are tight from the battery. Corrosion is hell. I jumpered...

You are correct about the exhaust elbow. It is what attaches to the manifold. Engine exhaust and water are directed vertically through separated channels up through the elbow and then down into the rubber coupler and ultimately out of the boat. I think that water and exhaust must mix at...

Well, I got t finished! Even though the cylinders were pretty smooth, the machinist recommended boring it .020 over and going with chromoly rings. Apparently they are more robust but require a perfect surface to seal on. Also another thing to note : while the pistons are standard 4"...

Well, I got it out of the boat with the help of my rust come-along and a 2x6 rafter and then took it to my father in laws for a dissasemmbly and inspection. It was kinda shocking how bad it looked inside. I am kinda ticked at the shop I just had it at. They charged me $600 to trouble shoot...

Thanks. I am currently pulling it to try to rebuild. My father in law was infuriated that a rebuilt 4 cylinder was almost $2k, so he said to bring it over and he would show me how to do it. I figure it will be a good learning experience.

Hi, I am going through the process of removing my 3.0LX from my 95 SeaRay 175. I have pulled the stern drive with drive shaft and have almost everything disconnected that needs to be. I am having considerable trouble removing the water inlet hose. In fact, I am unsure of where to remove it...

I have been researching options for either an overhaul or replacement longblock for my 1995 3.0LX. I have found longblocks ranging from $1600-2000 with warranty. However my father in law who is a mechanic and has offered to do the rebuild said that the could be done for way less if we just...

Unless u do the rebuild yourself, just buy a new longblock. I honk it would be cheaper and you an get a warranty too. Check out rebuilt.com, us engines, or Carolina machine.

Well, after several months of troubleshooting to no avail, I have come to the conclusion that my 1995 3.0LX motor suffered too much damage when it seized to run again. Apparently the exhause elbow had corroded and allowed water to leak back into the exhaust manifolds and then into the valves...

UPDATE: So I found out what is causing the problem but I dont yet know the extend of the problem. Apparently where the exhaust manifold meets the exhaust elbow had a rotted gasket which in turn corroded the manifold and allowed water to run back into the motor through the exhaust valves. So...

Had similar issues with my 1995 3.0. Same story (minus the outdrive issue). Engine was siezed and it would just click. Tried the battery straight to solenoid too. I ended up messing with trying to start it till it broke free, but now no compression. Sheesh. Try to get those plugs out and...

So I took it to a mechanic who is a friend of the family but is too damn slow at getting to it so I am gonna go to a legitimate (expensive) marine mechanic. The guy who has it now has said that he found water on the plugs after he ran the flush kit while trying to start it. And his...

Sheesh. That sounds really bad. I was hoping it was just a stuck exhaust valve that was causing the loss of compression. This sounds really expensive :-( Is there any reason why a regular automotive mechanic could not work on this? I can find one back in my hometown that is way cheaper than...
