Hello my name is ***** ***** am I speaking with?
The engine needs to be compression tested, is that something you can do?
I think the engine has low compression, it would fit the symptoms of black exhaust water. Can you do a compression test and get back to me with your results?
You are very welcome. Post back with your results and we can take it from there.
Got it. If you run the engine, does the engine actually heat up? Run the engine for a bit and then touch the tops of the cylinder heads and let me know if it's getting hot or not.
A 2003 BF50 should be a carbureted engine. Just to make sure, is your engine carbureted or EFI?
How does the engine otherwise run? Does it idle correctly, accelerate well, and make full power under load?
No more black water?
