Black Exhaust Smoke

[Greg_D]

While out for a short cruise and berth shift yesterday I noticed a LOT of black smoke coming from the exhaust. There's a lot of smoke stains on the hull round the exhaust outlet as well. The engine seemed very low on power and I was only able to get 2300 RPMs at full throttle. I'ms thinking the engine is acting like it is overloaded. Any ideas on where I should start looking?

Hi Greg,

I took your message, modified it a little bit and fed it into Grok AI.

Here is what it spit out; https://grok.com/share/bGVnYWN5_75711fd ... 010f676053

I don't always trust what AI comes back with, but this seems reasonable...

Wow, thanks. I never thought of doing that.
